SCIENCE - STATES OF MATTER
This half term, year 4 are learning about states of matter. After discovering what the properties were for each different state, I set year 4 a challenge. I gave them an empty bottle of water, a balloon filled with baking powder, some white vinegar and a funnel. The children poured the correct amount of white vinegar into the bottle and then attached the balloon to the top. After a countdown, the children tipped the contents of the balloon into the vinegar. All of a sudden, the vinegar began to fizz and the balloon began to inflate. The challenge was for the children to tell me what happened using their knowledge of states of matter. Ask your child to see if they can remember what happened and why!
