AP Biology Labs
 Cells
This is more of a holiday activity with a biology twist. A fun exercise that measures how much water is in cells and gives students a present to give to Mom! You could make this inquiry-style by choosing different varieties of apples, hypothesizing water content based on sugar, taste, and crispness. They can even do the water potential of each type of apple using protocol from osmosis/diffusion lab.(Each student could bring in 2 apples, one to test and one to make into an applehead doll).

Some photos to show you how to dry the apple heads and how to build the dolls

The apple heads drying on the radiator in my classroom. I just used a copy paper box turned upside down.

A completed doll. The rubberband is usually hidden by a ribbon. I buy squares of cloth at the local craft store.

A peak underneath to show you how the body is made from a water bottle. We cut the bottom of the water bottle and stick the excess cloth up inside.
