We investigated the best way to clean copper coins and it was with ketchup. It was a messy experiment but we had lots of fun.
Our challenge was to make a bridge strong enough to hold dinosaurs but we could only use paper and masking tape. It was tricky but we did it!
We also explored "Lively Liquids". We put half a raisin into a glass of fizzy lemonade and watch the raisin rise (the bubbles made it go up). Then we put vegetable oil and water in a bottle, added food colouring and an Alka Selzer. Lots of tiny bubbles attached themselves to the coloured water and went up and down as the bubbles popped.
