Will get my son to revise his weaker topics in the Ace assessment titles I bought last mth. Oh yes, I got sick of printing past year papers...bought CA2 and SA2 from a shop in Toa Payoh.
Material chapter is quite dry but certain terms are impt and cannot be mixed up.
actually the experiments on Materials chapter is quite interesting and doable. Do the experiments there with your child. Typically, they will involve inverting an empty cup over a basin of water. Do that with an empty mineral water bottle (small), so you can see the water level in the bottle.
You can put a straw in there to suck up the air and watch the water level rises, or you can drill a hole at the top of the water bottle and water level rises as air escapes, as you push the bottle into the water.
I find that if you do some of the experiments in the chapter, it will be a lot less dry. Have fun in the process.
The key words in this chapter is "Air occupies space". Always see that in the answer keys.
