Year 4 had fun yesterday experimenting with the properties of gases. First, we explored what happens when a sponge is submerged in water and the gas bubbles we could create by squeezing the air out.
Then we explored how gas is movable and can push objects.
After that, we put raisins in lemonade and observed how the gas bubbles made them float to the surface, where the bubbles would pop and the raisins would sink back down again. We learned that gas is lighter than water!
Finally, we did a magic trick involving a cup, some paper towel and a bucket of water. How did the paper towel stay dry?! Ask your child to find out more!
Year 4 were brilliant scientists today. Well done!
