What happens when we drink a lot of water? What does our body do to all the "nasties" in our blood? The Energy Heroes explored the urinary system. We saw our inner organs and realized that our kidneys, that do all the “dirty” work, are in the shape of beans. We talked about the importance of drinking water and saw what happens if we don't get enough. And since the sun was shining and the weather was sweet, we decided to take our experiments to our beautiful yard. The children worked together to build a model of our urinary system and the results were astonishing!
