Science Week in Room 3.

We did an experiment called dancing raisins. We put raisins into cups of water and predicted what will happen. They sank, then we recorded our results. Then we dropped raisins into some 7 up, they floated to the top and they sank  repeatedly.  We learned that the bubbles  were making the raisins lighter thus floating back up to the top, when the bubbles burst they sank again.
