Science - States of Matter - 6th Class

6th Class have been busy learning about solids, liquids and gases in Science.

We learned that states of matter can change from one state to another and, if mixed, can even create a different state.

This experiment proved that when you mix a solid (baking powder) and a liquid (vinegar) it can create a gas (carbon dioxide). The carbon dioxide filled the balloon. This experiment also proved that gases take up space!
