Dancing Raisins

When the soda water was shaken
we could see lots of bubbles.

Look at the raisins floating. It looked like they were dancing.
When they got to the top the bubbles popped and the raisins
sunk again.

Wow - can you see all the bubbles?
We think they are gas bubbles.

R13 investigators are amazing. Their questions and predictions are very interesting and show they are really thinking about the experiments.
