Today I brought vinegar, baking soda and a card with instructions so that my class could see me make a foaming monster. We mixed the vinegar with some dishwashing liquid and then added the baking soda. Our monster started to foam!
We were having fun doing a density experiment with oil, food colouring, water and maple syrup. We found out that the oil is the lightest. The syrup is the heaviest (most dense) and the water was in the middle.
