Year 3 became scientists for the day. They even wore white coats and goggles! They made coral reefs in small cups and made miniature volcanoes by mixing vinegar, baking soda, food colouring and a little washing up liquid. Later they got some dry ice and put it into coloured water. Guess what happened? It made bubbles and then smoke came out! When they put dry ice and water into a bottle and shook it, they even created a real rocket and it shot up into the air!
