Science


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.
