This might have been the kids favorite part of the experiment.

  • One bottle went into the fridge.
  • The other went onto the counter near the oven at room temperature.

Science Discussion:  We talked about how the yeast would act as bacteria would, if the balloon blew up, then the yeast was growing.

Step 3

When we got home, the balloon on the counter had blown up, but the one in the fridge hadn’t blown up at all.
