Properties of Solids, Liquids and Gas
Posted on: 14/09/2021As part of our Potions topic, year 4 have been investigating the different properties of solids, liquids and gases. We wanted to find out whether it was possible to inflate a balloon without blowing it up. We used bicarbonate of soda and vinegar to create a chemical reaction which formed the gas carbon dioxide. When the bottle was full with gas, it had nowhere else to go so inflated the balloon. The children really enjoyed the experiment!
