Simple science experiments are very popular in our Nursery and the children have learned to make predictions before they carry them out then observe what happens to see if they were right. As part of a focus on floating and sinking, the children experimented by putting raisins in lemonade to see if they would sink or float and, as you can see, they were very engaged in observing the changes they saw. They saw the raisins float as the bubbles of carbon dioxide stuck to them causing them to rise to the surface and were amazed when the some of the bubbles popped, causing the raisins to sink. This happened several times before all the gas was used up and, finding it hard to believe what they had seen, the children wanted to try out this experiment over and over again.
We thought that we would share some of the their comments.
Jackson: there’s bubbles. I put in the lemonade. The raisins are dancing.
Tom: bubbles move up and down.
Arthur: the raisins are going up and down.
Alexa: the bubbles stick to the raisins and make them dance. Bubbles give us hiccups when we drink them.
Nancy: we’re making the raisins float and sink. Look they’re dancing. The bubbles make them go up and down.
Jack: They are floating. Bubbles go up and down and make the raisins jump.
Sophia: I was putting raisins in lemonade. They were dancing about.
Emilia: look at the bubbles. They are dancing, lots of dancing.
