Dancing Raisins

Some students in class told me about an experiment Room 11 did called Dancing Raisins, I was very intrigued so I looked on their blog and decided to do the experiment with Room 2. Those students who had not heard of the experiment were told we were going to put raisins in a jar of lemonade and in a jar of fanta, they had to go away and write a hypothesis. After they had written a hypothesis we did the experiment and discussed why the raisins danced! The students went away and wrote what they saw and explained why it happened.

Hypothesis:
I think the raising will dance or turn fizzy.
What I saw:
The carbon dioxide made the raisins go up and down.
Why it happened:
Because the carbon dioxide pushed the raisins up and down. It was so cool.

Hypothesis:
I think the raisins will go fizzy and mushy or dance.
What I saw:
They were going fizzy. There skin was going flat but they didn't look like raisins they looked like grapes.
Why it happened:
because the carbon dioxide pushed the raisins up and back down.

Hypothesis:
I think that the raisins will dissolve.
What I saw:
The raisins went up and down.
Why it happened:
Because the bubbles had carbon dioxide which made them go up and down.
