This morning our little scientists have been carrying out more experiments and making predictions about the outcomes. We are learning about forces and describing their effects.
We started by filling three glasses- one with still water, one with fizzy water and one with super fizzy limeade. We then made predictions about about what would happen if we put a raisin in each of the glasses.
We then dropped the raisins in the glasses to test our predictions and were amazed by the results.
Through a previous bubble experiment, we have learned that bubbles have air called carbon dioxide in them. It is these bubbles that are attaching on to the raisins and making them float but when the bubbles pop the raisins fall back to the bottom as they are denser and heavier than water. This makes the raisins look like they are dancing. We then continued to add more raisins and discovered that the smaller ones were lifted up by the bubbles more easily.
”The bigger ones are heavier and they just make the bubbles pop.”
If you have some sparkling water and raisins in the house, please try this at home and share your findings with us @cartmillcentre
