Re: Questions about the E-Learning

I have found out a really simple answer to the question "Why and how did the density of water change when salt was added to it?". Really, the answer is simple, believe it or not. Salt actually just raises the density of water because the salt is adding mass to the same amount of volume. The video that Ms Leong put up actually summarises the entire meaning on the fact that salt adds mass to the same amount of volume of water.

HCI science class for term one

We learnt alot of new things in their from the day that our science class had started.We learnt how to measure things that i thought was impossible to measure such as the diameter of a wire. I never expected that science had alot to do with math. Even though I think that my term one effort for science wasnt enough, I really would want to strive hard for the following terms and years to do well for science.
