The Muscular System Week Three



                        With uncles that body build the kids were right into this lesson.  One of the first things we did  was weigh everyone we then multiplied the kids weight by 0.40 to show them how much muscle they had. They were impressed to learn their muscle made up 40% of their weight.

  We got out a timer and set it for five minutes, Natalie and Presley held their arms straight out away from their body, after 2 minutes both of them said they were getting sore. We talked while they were holding their arms out how the cells in the muscles were taking turns doing the work, but then they became tired. As a result, it starts to hurt your arms. The nerves don't get tired, but the muscles do! We talked about doing this everyday and that eventually the muscles would get stronger, and get larger.




Let's Face It!
We tried to make as many facial expressions as we could to move our muscles in our face. 
This is Natalie's "mad" although she kept laughing.

                                                   Friday's Experiment! Growing Muscle

This week as we discussed the more you use a muscle, the bigger it grows and the better it works.  We did an experiment, where we predicted how many times they could open and close a clothespin with their right hand for one minute.  We set the timer and began counting. It's a lot harder than it sounds! They are to do this everyday for a week and make a graph for the results and will likely see as the week goes on the will be able to do it more times in a minute than earlier in the week.
