Dancing Raisins

We conducted another experiment using the scientific method to question, hypothesize, test, record and draw conclusions. We put raisins in seltzer to see what would happen. Some of us hypothesized nothing, some said they would sink, still others said they would float. None of us were prepared for what happened! The raisins sunk to the bottom, but while we were recording this result, things began to change. The raisins became covered with bubbles and floated to the top, then would sink again. We observed closely, and then had a great discussion about the scientific reason. The student-to-student discussions were phenomenal!
