Do Cranberries Float?

Observe a cranberry (even cut them open) and then make a hypothesis about whether or not a cranberry will float in water. Plop a cranberry in a cup of bowl of water and see if you are right! For an extension, research how cranberries are grown and harvested.

Colorful Changes

Remember back when the kitchen chemistry class was looking at acids and bases, and we made homemade pH indicator with cabbage? You can do the same with cranberries. Try making cranberry juice, and see what happens when you add baking soda compared to what happens when you add lemon juice. The chemicals involved in the color change are called anthocyanins, and they are responsible for some of the health benefits of cranberries, as well as the gorgeous red color.

Can you think of any other experiments you can do involving cranberries?
