In Room 28, we have been learning about how matter can change. Last Friday, we conducted an experiment to find out which solids dissolve in cold water. We know that if a solid can dissolve in water, it is called soluble, and if it can't, it is called insoluble.
 |
| The solids we tested were sugar, sand, salt, pepper, coffee, oats and rice. |
 |
| We predicted which solids would dissolve before testing them. We did pretty well! |
 |
| If there was still solid material in the bottom of the glass after stirring it, we knew it was insoluble in cold water. |
 |
We worked in small groups and everyone had a turn at doing different jobs.
|
 |
| We wrote about our experiment too! We felt like real scientists today. |
Earlier in the week we also made cordial by dissolving flavoured sugar and jelly by dissolving jelly crystals. I wonder ...what else dissolves in water?
