The children love simple science experiments and are learning to make predictions about what will happen then observe closely to see if they were correct. Here a small group carried out their experiment independently, putting raisins in lemonade to see if they would sink or float and were very excited to observe the changes they saw. As the bubbles of carbon dioxide stuck to the raisins they floated in the lemonade and the children were amazed when the some of the bubbles popped, causing the raisins to sink. They tested this little experiment several times before all the gas was used up and wanted to try out this experiment over and over again. What great little scientists they are!
