Year 4 have been learning about Solids, Liquids and Gases in Science.

As part of this topic, the children have been experimenting and making raisins dance!

The children discovered that the fizz in lemonade (carbon dioxide) formed bubbles around the edge of the raisins. The bubbles stuck to the raisins and they got bigger. Eventually, the bubbles were big enough to make the raisins float, so they floated to the top of the lemonade. When the raisins got to the surface, some of the bubbles popped and the raisins sank. The raisins kept moving up and down until most of the carbon dioxide was gone from the lemonade and the lemonade was then flat. 

It was great fun to watch!
