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.
