We carried out an experiment called Potato Power! We discovered that our bodies are made up mostly of water and this water is contained in millions of tiny cells in our bodies. Plants are very similar to us in that they are made up of cells full of water too. The cells in plants and animals can dry up so they must be able to take in more water to survive. This experiment showed us how living cells dry up. We used potatoes as the cells in potatoes hold a lot of water. Here are our results. The salt drew the water out of the cells of the potato.
