Here is another great scientific experiment for our little scientists. Little scientist Diego called this experiment dancing raisins. He learnt that the fizz in fizzy drink is called carbon dioxide. Carbon dioxide is a gas that creates bubbles.
Tools: tweezers, magnifying glass, beaker
Extras: clear fizzy drink, raisins
Key science concept: the fizz in fizzy drink is called carbon dioxide. Carbon dioxide is a gas that creates bubbles.
What to do:
Check the video to follow the instructions from little scientist.
Can you see the raisins Moving in the beaker?
Tiny bubbles from fizzy drink collect on the raisins and cause the raisins to float to the top. When the bubbles pop, the raisins sink again.
For his experiments Little Scientist used the Primary Science Lab kit available from www.sciencemuseumshop.co.uk.
