Diary of... a Year 9 SCIENCE class January 29th 2007

Hi,
this is my first entry so please don't start with critisism.

OK, let's start:
today we started talking about Richard Feynman (if you wanna know more please see phoenix's entry -Andy's-). Then we talked about acids, salts and pH. I find very interesting to talk about these chemical themes. Our first task was to find out the definitions of these three words (acid, salt & pH) and write them down.
Afterwards, we had to draw a pH scale and doing it in some way different than normal ones for Andy said they were quite "boring". But, before finishing the scales, we tested some substances (like alcohol or vinegar) for their acidity or basity (Do you use this word?) with some universal indicator papers.
Finally, our hw was to do questions 1 & 2 of pg. 65. I'm not going to explain how to do them because you only have to repeat what we talked an read in class. Come on! It's too easy.
Well, see you next lesson.
