This week in Y3B we learned about types of materials; solids, liquids and gases.
Gases are a little more difficult to understand, as we usually cannot see them. We can only see places where gases are used and contained. For example, the air we breathe contains a gas called oxygen and the air we breathe out contains carbon dioxidegas. In order to show and see gas, we mixed vinegar with baking soda and gassy magic occurred. You can tell we had a BLAST by the priceless expressions on our faces.
