Things to look out for second semester 2008 @ 2:46 AM
Semester 2 is really short, you have effectively 3 months of study and Bang! Exams are on the door step.

I think right now I will share with you that you should look at the Exams and what you have to study as a whole. Semester 1 work will not be tested. So very lucky of you.

Anyway, for the sec 1, please take note of:
1. Parts of the river and how they are formed
2. How people depend and pollute the river.
3. Weathers & climates, what is the difference, how to measure temperature, rainfall and wind.
4. Types of climate, where each climate is found.
5. Types of vegetations and how they survive in each climate.

For the Sec 2(NA), really easy stuff:
1. Water supply, how Singapore deals with water shortage.
2. Pollution, seperate them into air, water and land and whether they are local, regional and global.
3. Global warming and ozone depletion, what cause them, what effects and what we can do about it.
4. Tropical rainforest adaptation, revision of sec 1 work, this might or might not come out, depending on the time allowed.

For the sec 2 Exp:
1. Learn the human environment through the 4 parts: Population, transport & communication, agriculture and housing, know how each is connected and affect one another.
2. Mapwork will come back again to haunt you. MUAHAHAHAHA! *cough*

Chapter 2- Essentially about characteristics about Earth, like its orbit, rotation, etc.

Chapter 3- The difference between the physical and human environment and how the !kung bushmen and the city people adapt to their environment. Lastly, how the human environment changes to suit people's needs.

Chapter 4- I will not be testing on the different types of maps, longitudes & latitudes, but I will be testing on the international timezone and you must know the parts of the map.

Chapter 5- Learn your 4 and 6 grid reference, cross section drawing of landforms, how to find actual distance on the map using the scale, bearings and compass direction. I will not be testing on gradient and curve line distance. The grid box distance is exactly 1cm both in height and width, so use your ruler and measure the 6 grid reference, instead of estimating.

Chapter 6- Be able to tell what is foreground, midground and background based on the features found in the picture. Know what is a landscape, aerial and satellite photo and how each are different. Questions here is tougher than before, so read what the question is asking carefully, before answering.

Chapter 8- Read and remember all the facts, that is all.

Chapter 9- know how igneous, sedimentary and metamoorphic rocks are created, know how each rock looks like and an example of each type of rock.


For the sec 2 N(A),

Chapter 2-Know your population pyramids and whether it represents a developing country or developed country based on the children, working and elderly population group. Know the difference between population density and distrbution. Know what are the factors that lead to increase and decrease in birth and death rate.

Chapter 3- Know what is a rural and urban settlement and the 3 different types of settlement patterns.

Chapter 4- Understand what is shifting culitvation, the steps involved and the slash and burn method. Know the difference between subsistence and commerical farming, what is the difference between subsistence and commercial wet rice cultivation. Know the advantage and disadvantages of high tech farming.


Chapter 5- Know the types of communication (printed media and telecommunication) and transportation, what is globalisation, what is entrepreneurship, what is a transport hub and how the world has become smaller.

Chapter 6- High human population and advancement in technology has lead to increase in pollution, know an example on how pollution occur at local, regional and global level and how the 3Rs can be done at individual, national and international level.

Chapter 7- Know how we are running short on land, how we can increase land supply and the problems comes with it, what is price mechanism, what is opportunity cost. Learn also what is mixed landuse, how we can increase farming land and its problem and why conserving land for the environment is important.

For the sec 2 express,

Learn how the fruits, flowers, roots, leaves of the tropical rainforest and mangrove forest help the trees adapt to their environment.

For pollution, global warming and ozone depletion, learn about the causes, effects and preventions. For chapter 6, refer to the sec 2 N(A), it is the same.

That's all for now.

Where are the bees? @ 5:40 AM
Read up on this site: http://viewzone.com/lostbees.html


It is about the lost bees, Einstein said that if the bees disappear, man will disappear in a few years time. What's your take on it.


A new movie by M. Night Shyamalan is based on the missing bees and what could happen to man as a result, below is a trailer on the movie:

www.apple.com/trailers/fox/thehappening



Sec 2 N(A) project @ 4:13 AM
Ok here for all the sec 2 normal classes, here are the details again:


The project is on creating a mind map or a flowchart on a vanguard sheet or equivalent poster size (larger scale posters are allowed too, not smaller) on the four factors of the human environment: Population, Settlements, Agriculture and Transport & Communication. It will be based on chapter 1 to 5 of your textbook.

You will need to form into groups of 2 or 4. Those who are in groups of 2 will automatically get 10 points extra.

The dateline of your project will be on 19th March 2008, Wednesday.

The diagram below is a simple example of what is expected of you.



The project will be awarded upon the following criteria and is upon a total of 50 marks:
Completion of at least 6 components of each factors above in the diagram. (25 marks)
Additional information on each component and additional factors. (10 marks)
Additional linkages to each contributing components or factors with explanation. (15 marks)
Bonus marks of up to 15 marks will be given for additional pictures and charts with explanation and links to the chart. (15 marks)



Sec 1 guide books and other stuff for sec 1s. @ 4:13 AM
Please take note that the books should be in by next week. The bookstore keeper is currently trying to remove the GST for you all, so does who paid extra for the GSTwill get a refund if he manages to get the discount.

Sorry for not writing lately, been really busy and sick with flu too. Anyway, given how you all are not comfortable with map reading, I am going to go through it nearing the mid year exam.

For photograph interpretation, here are some ground rules:

1. Only landscape and aerial photos taken at an angle can be splitted into 3 parts: Foreround, midground and background. Be aware of your perception, things further from you are always smaller.

2. Describe what you can see and identify. Do not describe something you cannot see clearly or explain clearly, especially in satellite photos.

3. If you are not sure but you want to explain a weak point across, provide a good argument. For example, you see a man standing on the roadside, you can suggest that the man can be crossing the road or you can say he is waiting for a cab. A weak point is when you say he is waiting for someone. To put your point across, a good argument could be is he is not looking at the oncoming traffic, so he could be waiting for someone. That is how you can score more.

Thursday, February 21, 2008
Chapters to study @ 12:56 AM

More common test tips @ 5:28 AM
For the sec 2 (NA), as explained in class, I indicated that the mind map is important and it will reflect well on what is needed to be known. Focuse on describing population pyramids and that bigger the area, the bigger the population. For settlements, you should focus on the 3 types of settlement patterns and how each pattern is formed by certain key factors.

For the sec 2 express, please learn about air pollution, particular about haze in Singapore. Roots and fruits of a mangrove tree too is important. I cannot say much about the other questions, but be aware of those questions that are from chapter 6, read the question carefully, the answers are not so direct.

For my sec 1s, I have ask you all to do workbook 5.2, given the time constraint, I will share the answers with you now.

(a): A is legend, key or symbol, B is north arrow, C is scale.

(b): 1:50,000

(c): 5747

(d): Above 1050m

(e): 16º(±1º)

(f): 800m

(g): 575444

(h): Houses, a mountain

(i): A steep slope, there are closely spaced contour lines.

(j): 565462

Trignometrical stations for sec 1s @ 4:22 PM



Trigonometrical stations are key points that show the height of a hill or a mountain and is the highest point of the physical feature. On a topograohical map, the trig point will have the highest point value in metres. For more details and how it looks like, refer to your textbook page 34.




You can go this website at: http://en.wikipedia.org/wiki/Trig_point and to find out more why and how they are used refer to: http://en.wikipedia.org/wiki/Ordnance_Survey. At the bottom of the last website, you can find links to different organisations around the world that work on this surveying of our Earth.




Hint: I hear a test round the corner ask about the highest point.



Tips for the common test for sec 1s @ 4:32 AM
Hi all, sorry for the late entry, but here are the stuff for you all to learn.

For chapter 1, know what is a feature and a environment, know the difference betwen physical and human features.

For chapter 2, learn the Earth's movement and how they create the seasons and what happens to that annoying 1/4 day for each year.

Learn chapter 3 well, many of the questions will be coming from there, things about why is it important to protect our Earth, how the !kung bushmen and city people relationship with their environment.

For chapter 4, know about international time zones, your textbook is more than sufficient to explain what you need to learn. Latitudes and longitudes too are important, learn how to use them. The world map as shown on your notes is important too.

For chapter 5, please take not on the reading of 4 and 6 grid reference (REMEMBER: EASTING-the vertial lines are read FIRST, then NORTHING-the horizontal lines are read next, no commas or dots are needed)
Be able to determine your compass direction and bearings.
Know how to find the contour interval.
Know what is the highest height you can read on the map, look at the contour lines.

I will try to update more along the way before the test itself.

stuff to bring for exam @ 6:32 AM
Please bring your CALCULATOR & RULER tomorrow. Please inform your class mates too. I will try to come to school earlier, since so many of you are crying for help.

Saturday, September 29, 2007
Added notes on the exam @ 7:50 PM
Please remember that in the exam, that for every marks you are given, you must write down at least one point. For example, if the questions is worth 4 marks, you must write down 4 points for your answer. If you are not sure of your answer, write down more to be on the safe side.



Lastly, for the express stream, please take note that your paper is harder and so you must know your facts well. Stick to what I say about using the rubric for the natural vegetations and you will be fine. Here is a example of what you can do:

Take note that for the Normal classes the rubric is the same for you all for chapter 18, but you do not need to learn about the adaptations and distribution. However you do need to need to know the adaptation and dstribution of the tropical rainforest. You can find your information in chapter 19.


Friday, September 21, 2007
Exam, exam, exam @ 10:52 AM
Please take note that the exam questions will be based on chapter 14 to 21, N(A) classes will not need to learn chapter 20 and deciduous and coniferous forest in chapter 19.

What to take not of in the chapters:

Chapter 14:
Learn the Benefits and problems that the river brings and the same for the Aswan High Dam. PLEASE know the difference between the dam and the river!

Chapter 15:
Learn about calculating annual rainfall, mean temperature & temperature range. Find out about parts and placing of the rain gauge and stevenson screen.

Chapter 16:
Find out the distinct features of the climographs of the three climates, polar, temperate and tropical.

Chapter 17:
Learn about the types of positive and negative effect of the weather and climates.

Common test info @ 3:28 AM
For a start, it is chapter 14 to 18. I will keep it brief and I will answer questions for the next few nights till the common test.

Chapter 14:
Know briefly what are the advantages and disadvantages the Aswan High Dam brought to the Eygptians, you do not need to know about the salinity, I will not require you to know.

Chapter 15:
Know the difference between weather and climate.

Know how to calculate annual rainfall, mean temperature and temperature range for daily, weekly, monthly and annually.

Before you start screaming your head away at the formula, READ CAREFULLY the similarity for the temperature formula, the only difference would be that the MEAN DAILY TEMPERATURE IS (HIGHEST TEMP + lOWEST TEMP)/2.

Know a few things about the Stevenson screen and the rain gauge, it is all in your notes.

Chapter 16:
There are only 3 climates to learn: Tropical, Temperate and Polar. Know how to recognise the climograph for each climate.

For tropical, it NORMALLY has high rainfall, high temperature & low temperature range. Meaning it will have alot sunlight & high humidity.

For temperate, it NORMALLY has evenly distrubuted rainfall & high temperature range. Meaning it has the 4 seasons and temperature can range from hot (above 21ºC) to cold (below -10ºC)

For polar, it NORMALLY has low rainfall, low temperature and low temperature range. Meaning the area is normally covered in ice and snow, with little rainfall, sunlight and humidity. There is a possibility that there might be a short period of time in the centre of the year where the temperature will be higher than normal with similar amount of rainfall.

Chapter 17:
Know the positive effects (consistent weather and climate pattern) and negative effects (inconsistent weather and climate pattern).

Positive:
1. Wind and solar energy
2. Tourism
3. Farming

Negative:
1. Drought
2. Flooding
3. Heat wave
4. Cold wave
5. Extreme wind

Chapter 18:
For the normal stream, you do not need to know the latititude or the locations, but you need to recognise the vegetation from the picture and describe the climatic factors for the plants there like rainfall, temperature and sunlight. Remember that the higher the rainfall, the more plants. Sunlight and temperature go together.

For the express stream, you must be able to know which form of vegetation exist based on the climograph, look at the annual rainfall to decide if it is a forest (above 750mm), grassland (below 750mm) and desert (below 250mm). Then to decide which sub categories they belong to, look at the temperature. For example, high rainfall and high temperature means it is a tropical rainforest. Low mean temperature (below -10ºC) and higher rainfall & temperature in the middle of the year means it is a coniferous forest. I know this is hard, but do not worry I will not set hard questions in this chapter. To help you better undertsand this chapter, read up on this sites to better help you, it will also help you for chapter 16.

@ 5:56 PM
I like to inform you about my mistake on page 129 of the textbook. The map's legends are correct, the legends are correct to each region, as they are actually representing the TEMPERATURE RANGE, not the MEAN TEMPERATURE for each region. Nonetheless, do not worry about it, refer to my notes as it would give you a better description about climatic maps.

Sunday, July 8, 2007
@ 5:46 PM


For the last part of the chapter 15 which I will be covering this week, climographs and wind rose are the more difficult ones to learn.






For the weather map, you must be able to evaluate what does wind speed, wind direction, rainfall and temperature will tell you about the atmosphere in the area. The next thing is to figure correctly what would possible happen in the next few hours based on the information present.






For example, If there is sky is cloudy, strong winds are present and the temperature is cooler than normal, what would possibly happen in the next few hours? If you say it is going to rain, you are on the right track. If you say otherwise, well I guess you better get out more and look at the sky more often. ;P






Next thing is climatic map or commonly known as climate map, please note that the legends of the climatic map on page 129 of your textbook is wrong, please ignore the entire map, you will get more confused reading it. Climatic maps are used to tell what kind of climate exist in the world or in regions of the world, such as the one below. They normally tell you about the temperature or the amount of rainfall in each area.




As for climographs, they are the most common charts used to describe the climate of a region over a period of one year. They normally tell you about total rainfall and mean temperature for each month of the year. It is hard to get accurate reading from them when you start calculating, but I will normally give a generous buffer in the deviation, so don't fret unnecessarily.


I recommend using a ruler to measure correctly, when finding the annual rainfall and the annual mean temperature. Try doing it first and you will get what I mean. Here is an example of a climograph, notice that the rainfall reading are the bars and the temperature are connected dots.


This site has alot of information that will help you in your studies about climographs. (Hint: also alot on chapter 16, use your textbook as reference)
http://www.uwsp.edu/gEo/faculty/ritter/geog101/textbook/climate_systems/outline.html
Next up is the wind rose, unfortunately, I cannot explain in great detail here, as it will need some personal guidance, words just do not describe well how it works. Don't fret again, it is not hard. If you need some assistance to understand, this site will help you.
http://www.bom.gov.au/climate/averages/wind/wind_rose.shtml
That is all for now, there will be an open book test on this chapter worth 20 marks. Do well in this because it will help you alot in the following class test and common test.

Of tests, exams and chapter 15 @ 6:43 PM


Tentatively, there will be tests every week, only unless there are holidays or other events that clash during that week. Nontheless, with only 12 weeks in this term to teach you all 7 chapters for the normal classes and 8 (chapter 20 included) for the express, I recommend all to read up the following chapters before coming to class.




The exams will include chapter 14 to 21 (exlcuding 20 for normal classes), this time round it should be easier than the first semester's exam, so I am expecting much higher number of passes.




Next, in order to prepare you for chapter 15, here are a few major tips (which actually if you read your textbook, you do not need)




1. Max & min temperature


mean (mean = average) temperature: (max-min)/2 ....duh




2. temperature range


max temp- min temp




3. Rainfall


READ THE BOOK, VERY STRAIGHTFORWARD.




4. Wind Rose


The one with the longest arm shows which direction the wind is blowing most constantly. Take note that a wind rose is NOT a wind vane. Here are 2 pictures to show you the difference.







The one on the left is a wind vane and the one on the right is a wind rose.

The rest of the material I will present in class, it is a fun topic and I think you all will enjoy it.

Happy Holidays and notes on Rivers & People @ 6:07 PM
Happy holidays, hope everyone is enjoying their holidays. Anyway, remember to do review exercise. The things to take note about chapter 14 is that there are both positive and negative impacts that the river can have on people. The positive impacts that rivers have on people can also lead to people abusing the river for those uses and in the end polluting or damaging the ecological system in the river. I will not go into too much detail, as I can see alot of you understand this part of the chapter.

Please take note that the River Nile and Aswan high Dam case study is different from the rest of the chapter, as it builds upon your understanding from the earlier part of the chapter. The problems and benefits that the Aswan High Dam can be summarised as followed:

Benefits:
1. Hydroelectric energy.
2. Water level is same throughout the year.
3. Crops can be grown throughout the year.
4. Boats can travel up and down the year throughout the year.
5. Arid (dry and infertile) land now be irrigated (watered) to become arable land (land is good

Question: Why does point 3, 4 & 5 related to point 2.
Problems:
1. Less sediments are flowing down the river.
2. Farmland down river are less infertile.
3. Fish population are reduced.
4. Habitats are reduced, animals and plants species and populations are reduced.
5. People have to leave their homes and houses upriver.

Question: Why does point 2, 3 & 4 related to point 1.

Here are a couple more sites you can go and read up about.

http://geography.about.com/od/specificplacesofinterest/a/nile.htm
http://en.wikipedia.org/wiki/Aswan_High_Dam

here is a site on arid and arable land:
http://geography.about.com/od/physicalgeography/a/deserts.htm
http://en.wikipedia.org/wiki/Arable

Those of you who are going on holidays, take some photos of what you think is arid (dry) land and arable (fertile) land. A good tell tale sign if it is barren with little plants (arid) or is any farming (arable). We can share the photos when we come back to schoool.

Exam Tip 4 and final tip @ 6:58 AM





I anm quite tired of you all asking me what chapter to study, It should have been obvious from the chapters I covered, chapter 1 to 13 excluding 7. Focus less on chapter 1, it is not the most important. All classes please take note to collect you test papers and files back from the pigeon hole.






Anyway, let me continue with the rest of the tips for the following chapters, it will be very straightfoward.






Chapter 8:



Know your landforms, like what is a valley, plateau and plain. The difference between hill and moutain.



Know the 3 types of benefits landform can bring about. And how mountains can be a natural barrier and the dangers living on a mountain.






Chapter 9:



The 3 layers of the Earth: Crust, mantle and core.



Understand the crustal movement and what is convection current in the mantle and what it does to the crustal plates.



What is folding process and how fold mountains are created.



What is vulcanicity and volcanic eruption.



Parts of the volcano: magma chamber, pipe, vent, crater. Remember cone is not part of a volcano, it is the volcano.



The 3 types of volcano: active, dormant and extinct.






Chapter 10:



The benefits of living next to a volcano: fertile soil, mining minerals like gold , getting geothermal energy, tourism, cultural and traditional icons and lastly jobs and improve economy (state how they produce jobs and improve the economy)



The dangers: Vulcanic bombs, poisonous ashclouds and lava flow. You know the story behind it all.






Chapter 11:



The difference between weathering (breaking of rocks into smaller parts in situ) and erosion (wearing of rock surface and eroded parts are carried away)



3 types of mechanical weathering: Extreme temperature change (indicate exfoliation), freeze-thaw action and weathering by plants.



Chemical weathering by acid rain, how rainwater and carbon dioxide in the air mixes to form carbonic acid.



Erosion by wind, water and wave. (they all work the same way, all carry sediments like sand and abrade the surface of the rock)






Chapter 12:



Follow my notes. (remember very clearly how each of the 3 rock's crystals are sized, fine, mid and coarse)



Know the uses of granite.



Be able to recognise the 3 types of rocks.






Here are some pictures from UCDavis, University of California to help see better.






Chapter 13:



This is very straightfoward, you should be able to ace this.



Know the earth water distribution in percentage and why it is important to conserve water.



The water cycle: what happens at percipitation, transpiration, condensation, surface runoff and groundwater flow.



Each drainage basin is seperated by a watershed



Parts of the river:



Upper course: (in descending order)



River source (part of the drainage basin)



Tributaries(part of the drainage basin)



Waterfall (find out how they are formed, remember the hard rock comes before the soft rock)



valley



Middle course:



meander (can also be found in the middle-lower course too)



Lower course:



Floodplain



Delta (river mouth, formed by deposition of sediments)






Note that as the river flows down from the mountain, the water will flow slower as the gradient of the land become gentler towards the sea and there is less gravity pull on the water.

Exam Tip 3 @ 9:30 AM
For the next 3 chapters, chapters 4-6, you have to take note of the following:

Chapter 4:
Know the purpose and a general idea of what each map is.
Know your latitude (horizontal lines, running from 90N to 90S) and longitude (vertical lines, running from 180E to 180w)

For express students, you also need to know what is the international dateline is and how to read the different time zone. A simple method to rememeber is when the question ask you what time is country X is when Country Y is 9am.

1. count the difference in the number of hours between each country by looking at the timechart below (use your textbok page 34 for reference).

2. Minus the hours from 9am if the country X is to the left of country Y and add the hours to 9am if country X is right to country Y.

Chap 5:

Mapwork, something I have repeated countless times.

1. Know the parts of the maps like in page36 and 37 of your textbook.

2. Know how to use the scale, remember that the scale is always in cm, unless otherwise stated and convert the final value to Km.

3. 4 and 6 grid reference, read the easting value (values at the bottom part of the map running from left to right), then the northing value (values at the left side of the map running from bottom to top). 6 grid reference must always be taken with estimation the 3rd and 6th values can only be from 0 to 9. If the 3rd and 6th values is 0, then point will cut across the gridline.

4. Compass direction, if the question ask you to find the compass direction of A from B. READ FROM B!!! THAT MEANS THE POINT OF REFERENCE IS B, NOT A!!!!

5. Bearings, check my previous post.

6. Cross section of landforms, here are a few things for you all to take note:

a. Draw your cross section line first.
b. Draw your contour lines and add the contour values into the cross section box. Remember the bottom part of the box is '0' metres.
c. Draw straight lines down from each contour line to the the respective contour line in the contour box with a ruler.
d. Use freehand and join the points where the lines cross each other and the shape must start from the bottom and the highest point must be slightly higher than the highest contour line.

Chap 6:

There are 3 types of photograpghs: Landscape, aerial and satellite and there are mainly 2 types of human settlements, urban and rural.

Be able to recognise what is human features and physical features. The more buildings there are, the more urban it will be is a good rule of thumb.

Landscape photographs can be splitted in foreground, midground and background. Be able to describe each part with at least one detail. It is unlikely that you will find one with nothing to describe.


That is all for now.

Exam Tip 2 @ 7:56 AM
A conglomerate is a sedimentary rock that comprises of different types of rocks cemented together. Secondly a schist is form of metamorphic rock.

First of all, here are a few tips to remember for the first 3 chapters.

Earth rotates 24 hours a day and revolves 365 1/4 days per year and orbits at 66 1/2 degrees to the plane of orbit.

A good steward is an individual that helps protect the Earth from environmental damage.

Physical enviornment - an environment untouched by man.
Human environment - an environment created by man to suit his needs.
Physical feature - a feature created by nature.
Human feature - a feature created by man.

A rural settlement is a human environment with low human density, few human features and high physical features.

An urban settlement is a human environment whith high human density, high human features and low physical features.

The !kung bushmen adapts to their environment by taking only what they need.

The city people change their environment to suit to their needs.

The methods of adaptation by both city people and the bushmen, I will leave it to you to read the textbook.

I will update more on the following chapters in time to come.

Exam tips @ 8:39 AM
Let me address some of the problems at hand first that came on the tagboard, you can post as me as much as you want, but you cannot get into the blog, so a big 'HAHAHAHAHA' to you all posers.

Secondly, a few questions that came up on the blog.

Fieldwork-It is to go out to the site or area of concern to do research on the topic that is being investigated. For example, I want to find out how many bugs are there in a park, so I go to a park and start taking samples from random places around the park and count how many bugs there are.

Crustal movement- it is the movement of the crustal plates caused by the convection currents of heat moving in the mantle. when two currents meet, thecrustal plates will collide towards each other. When the currents move away from one another, the crustal plates will seperate.

In regards to the other chapters, I will update again tomorrow, I am very tired now, need to sleep.

Thursday, April 19, 2007

Chapter 4: The types and uses of maps, What is latitude, longitude, greenwich or prime meridian, equator, International Date Line & time zones (for express students only), How to read longitiude and latitude.

Chapter 5 (the killer): 4-grid reference, 6-grid reference, Easting, Northing, scales, compass direction, measuring distances, bearings, Drawing cross sections of landforms (with all the required parts)

Chapter 6: the 3 types of photographs, their advantages and disadvantages, how to see the foreground, midground and background of landscape photographs, recognising human and physical features, rural or urban environment.

Chapter 8: Explaining the 5 types of landforms, describe the positive and negative effects of landforms.

Chapter 9: Where is the core, mantle and crust? How is crustal movement caused by convection current in the mantle? What is folding and fold mountains? what happens when plates move away and towards each other? What is vulcanicity? What is the relationship betwen magma, lava & cinder? How is vulcanic eruption caused by? The parts of a volcano. How is a cone volcano created? What is active, dormant and extinct volcano?

Global Dimming @ 10:06 PM
Well, here are the links of what I was talking about global dimming. It is the new twist to how the world might end. I would like you all to think how does the lack of sunlight will kill the world and what we can do to save the world. The answer is very easy, but strange and sad thing (like you teacher, =P) is that most of the world can't seem to accept the answer as a solution. Think about the answer if you can and post it up.

http://en.wikipedia.org/wiki/Global_dimming

http://www.bbc.co.uk/sn/tvradio/programmes/horizon/dimming_prog_summary.shtml

A very controversial program about global dimming:

http://www.informationclearinghouse.info/article15809.htm

Here is a famous blog on global environmental issues and their take on global dimming.
http://www.globalissues.org/EnvIssues/GlobalWarming/globaldimming.asp

Another good video:
http://www.pbs.org/wgbh/nova/sun/dimming.html

Anyway, don't dread too much, Scientist has put the dateline when we really suffer the effects of it and the possible point of no return at about 10 years from now, so you will be about 23 years old. At least, if the world ends, you be an adult. So put a smile on your face, Mother Earth has awhile to live and yes, it is not tested.

Fine grained and coarse grained igneous rocks @ 7:02 PM
To sec 1C, 1E, 1F and 1H, I apologise for making a mistake. granite is coarse grained and pumice is fine grained. Pumice is fine grained as it cools faster, so the crystals become small and do not have the effect of the heat to expland the crystals slowly.

If you need more help to clarify this matter, please look for me. Thank you.

Mapwork @ 7:11 AM
As promised, I will show you all again the step by step procedures of the common map work techniques for you all.

First we will start with compass direction.
Let's look at how a question will be phrased, "what is the compass direction of the city from the farm. take note of the "from" word in the question, it indicates the location you should take your reading from.

Follow the following steps to get the answer.









1. Draw a north line on the farm.

2. Draw a connectiong line between the farm and the city.

3. base on the north arrow, find out where the connecting line is located at.

The connecting line lies in the Northwest region, so the city is Northwest of the farm.


Bearings

Let's use the same qustion as above, but we will now find the bearings. So the question will go like "What is the bearing of the city from the farm?"

Repeat the first 2 steps like in finding compass direction, then draw a clockwise circle starting from the north arrow to the connecting line, just like in the picture below.


1. Draw a north line on the farm.



2. Draw a connectiong line between the farm and the city.


3. Draw a clockwise circle starting from the north arrow to the connecting line.


4. Use a protractor to find the angle starting from the north arrow, the diagram below will give a good idea wha the bearings should be.



Based on the diagram above, we can see that the angle should be between 270 degrees and 359 degrees. Remember that bearings only range from 0 degrees to 359 degrees. 360 degrees is the same as 0 degrees.



Gradient



Many students have come to ask me about this. The gradient is simply height over distance or height/distance. the questions can vary in regards to gradient, but the formula does not.



here is an example of how a question can go about. Look at the part of the map above (looks familiar? ;P) Find the graident of the slope along northing line 29. Do the following steps to get your answer.


1. Locate northing line 29.


2. Find the highest and lowest contour line on the northing line 29.


3. find the difference betweem the highest and lowest contour line, which in this case is 100-20=80m. Remember contour lines are always measured in metres.


4. Next, use a ruler to find the distance of the northing line 29 from the side of the map to the lowest contour line, that will be your distance.


5. Multiply the distance with the scale which is 1: 50,000 on this map (look at the bottom part of the map), remember to convert to metres (divide by 100). All scales are in centimetres, unless specified otherwise.

6. Finally, divide the height by the distance and reduce the answer to a ratio of 1: distance. For example in this case, let's assume the distance is 1000m. So the gradient is 80/1000 which is then reduced to 1:125. That means for every 125m that you walk on the hill, you go up by 1m.

I will cover the rest on mapwork if need be, but I think the rest you all are able to handle so far.

Map work retest @ 8:25 AM
Please take note that the retest will be done next week in the afternoon after school. I will come to your class and inform you when the test will be.

You can check this site to help you understand better.

Look at the basics of map reading 1 and 2, they provide good material.

Earth day badge design and poster @ 8:02 AM
As in regards to a post here, the badge is 5.5cm in diameter. In your group, design a badge on a piece of paper and write a summary of about 100 words explaining your design under the design itself. The top group will win a prize and a grand prize among the other top groups in the level.

I also understand some of you have problem understanding what to do for the competition. Essentially, you have to design your badge or poster with regards to Earth Day. The theme of your design can vary from the 3 Rs, reducing pollution, protecting our ecosystem, conserving our resources or anything that helps the Earth.

If you are in doubt, post again, but state your questions clearly, I cannot understand brief statements.

Been sick the past week, but here is the headlines @ 11:06 PM
A big sorry to everyone, I have been sick the past week and I haven't really been updating my post as of yet. Anyway, like to point out a few important things for all of you.

Firstly, in the new set of worksheet I handed out, please skip page 3 all together, it is too hard.

Secondly, on page 2, draw a line across the slope on the top right hand corner of the map and label both ends with 'B' an 'C', this is for question 3 on the same page.

Thirdly, I will be covering mainly chapter 5 for the remedial and again I stress it is mainly for those that had failed in the previous common test.

Now some of you might be also wondering why your grades in your report card with that of your common test, it is because I had to add in your class test results and that lead to the change in the final results.

Finally, I would like to extend a warm welcome to my blogging committee, but I am still missing out on 1F and 1G bloggers, could someone in either class please volunteer, as I have some activities for you all to do.

Updates on lessons @ 7:42 PM
I will be finishing chapter 5 next week and I will be giving out a class quiz for you all to do. Additionally, I like you all to do review exercise page 49 to 55 in your workbook for your 1 week holiday. This should prepare you for the class test that will be held in the third week of March, 2007. The class test will cover chapter 4 and 5.

Blogging Committee @ 7:37 PM
I am going to start a mini blogging committee with a representative from each class, among them a leader and assistant leader will be selected too. I will like to hear from the rest of you how we can make this blog more interactive for everyone to be involved.

I would like some students from each class to contribute some things they have learn in class or on their own. This will be posted up on the blog with their photos (or not if you are not comfortable).

I guess the task to help me out with the blog would be of great interest to the committee, but I would like to add that any material that is to be posted on the blog have to be emailed to me for approval.

Again, suggestions and more suggestions please. Like I said many times before, I set the paper, you sit the paper. May the study force be with you.

International Dateline, Prime Meridian and Greenwich Meridian @ 6:39 AM
I think I need to clarify some matters on the International Dateline, Prime Meridian and Greenwich Meridian. First of all, the 0° longitude is not the international dateline, it is known as the prime meridian or Greenwich meridian. The 180° longitude line halfway across the world is the international dateline.

Please note that only the express stream will be tested on this material.

The key confusion alot of you seems to have is how people loses and gain one day. A easy way to understand this part is that you must first accept that at the 180° longitude, people west of this line is a full day earlier than those on the east.

If you are going westwards from the prime meridian to the international dateline, you minus an hour for every 15° you travel westwards on the planet and add an hour for every 15° you travel eastwards on the planet.

Check up on this sites if you want find out more about the international dateline,

Remedials, study groups and extra stuff @ 6:22 AM
It seems alot of you are very interested in learning alot more and really want to make a new design for this site, I am all for it. If you want to do so, please leave your name, class and class index on the comment page. I will get back to you and I might start a blogging committee for the sec 1.

I got a comment on the study groups too that some of you want to go solo on your quest, it is fine by me, like I said: I set the paper, you sit the paper. If you think you do better going on your own, I am fine with it too. As for remedials and study group, I will be starting one up by next week. Places will be limited and those that have failed the common test will have 'special priviledge' of having the first priority. Lessons as usual will be upstairs in the IT Resource Room 1 probably about at 2.30pm (I have to eat my lunch first) and go on for an hour. lessons will be informal and the focus will be on areas that you are weak on. Note that study groups can join in too, but do not be surprise if I take some of you to help teach you schoolmates.

Lastly, if you do start your study group, stick with it and try out other chapters on your own if the interest compels you to do so. So go forth and venture into the dark!

Ownership @ 7:44 PM
I had several students last week looking for remedial and more homework, I am very happy to see that some of you are beginning to take ownership of your studies. I shared some suggestions with them that I would to share with the rest of you too. First of all, I like to point out I am not going to enforce or insist that you must do so, but I am strongly recommending it.

Get into groups of 4 to 5 and buy external assesment books to do. That way you can split the cost of the book and you can come together to discuss your answers too. The benefits of doing this is 2 folds, firstly you can improve on your answering techniques on different types of questions and compare your answering with the answers at the back, secondly you become more confident in Geography and learn to take ownership of your studies.

Don't worry about trying questions that is outside of the chapters that I have not covered, it is fine, by taking the effort to move ahead of your teacher is exactly what I want, afterall it is all teacher's hope that their students become better than their teacher.

Here are some examples of books that you can try, don't worry I am not the companies sales representatives.

Longman Geography: Revsion Guide Sec 1
Penman's: Student's Companion Series, Geography Sec 1

I will try to look up for more other assessment books.

Topographical Features @ 7:40 PM
Check this link on more detailed descriptions on topographical features, this will helpp you greatly in understanding page 48-50 of your textbook, under chapter 5.
http://reynolds.asu.edu/topo_gallery/topo_gallery.htm

Just look at the simple features on this link, it is not necessary to look up on the complex features.

How to study geography @ 6:10 AM
There are many ways in studying, but my personal opinion is that understanding is the key to get the most of your studies. The 2 main methods I normally use and encourage in Geography is to:

1. Mindmap-
Break down your chapters into topics, sub-topics and details. Add on more links when you learn more. In fact, all the chapters in your textbook are connected one or another.

2. The 5 Ws-
What happened
Who was involved
When did it happen
Where did it happen
Why did it happen

The 5 Ws are the key in understanding any event or subject, by answering those questions will help you with better understanding of any topic.

Take note that tips are not to help you directly getting better results in your tests or exams, because another factor has to be taken into account, which is answering correctly.

Common test 1-2007 review @ 5:23 PM
So far there has been a mix of passes and failures, but mainly passes. Strangely, I have only one full marker with many many others breathing down his neck. I like to address a few things that I have came across when I was marking the paper that I want to bring up to everyone.
1. Things, objects, details & features-using the terms correctly
I give some of you the benefit of the doubt on the use of your english for this paper and I have closed one eye on your language, since the objective of the paper is to gauge your understanding of Geography and not your english. Nonetheless, make it a concentious effort to use the right wording. Things and objects are all reference to the word feature. Details are not. Details are descriptions of the feature, so if you are using the word details, you have to use the word feature along with it. For example, 'The details of the features are...' So be careful in your writing.

2. Rural & urban-the difference
There are still some people struggling with the term rural and urban. PLEASE REMEMBER: A rural settlement is a place with few buildings like a village or a 'kampung'. A urban settlement is a place with alot of buildings like a city or town. Do not describe the activity there as a form of settlement, unless I specify in the question.

3. Read your questions and answers carefully
The age old problem with students, I still have students not answering to the questions. READ the question carefully before answering. Lastly, READ your answers before submitting, I have a few cases of students writing the right answer for the wrong question.

Please take note that aside from this issues that I have highlighted, I also do note that many girls have a problem answering correctly to the point, although you may have gotten some marks for your answer, it was mainly based on the strength of youe english to pull your results up, but it will not be helpful for the next class test on chapter 4 and 5 which will be on purely understanding.
