This is a great way to show kids how germs are in our food and “see” the need to refrigerate our food to limit bacterial growth.
- 2-3 glass soda bottles
To do the bacteria experiments:
We dropped one teaspoon of yeast into each bottle, then we filled each halfway full of warm water and put a balloon on top. One bottle went into the fridge, and one went onto the counter near the oven.
We talked about how the yeast would act as bacteria would, if the balloon blew up, then the yeast was growing.
