Here's another science experiment we're in the process of completing. We're demonstrating how your muscles get stronger as you use them. Norah opens and closes the clothes pin as many times as she can with her right hand for one minute and I record the number. Then she does the same thing with her left hand and I record that number, too. As you can see, after only four tests, her numbers have gone up. We are well past the chapter on the muscular system, but I think we'll keep doing this experiment anyway and see how high Norah's numbers go. Norah seems to enjoy it and it makes for a nice break in our school work. I am sure the same test could be done with something more physical, like hopping or jumping rope or push ups.
