1. Was it difficult to use the same technique throughout the whole experiment?
2.How did you hands and fingers feel BEFORE, DURING, and AFTER the experiment?
3. Is there a pattern to your data table or graph? Do the numbers increase, decrease, or stay the same?
4. What could these patterns in your table or graph indicate?
5.Are your results reliable? Is there anything you could have done to make your results more reliable? Explain. What errors or inconsistencies might have affected your results?
6. Why did your hand strength change over the course of this experiment?
7. How do you think your muscle cells get oxygen, nutrients, and water to make the energy they need to function?
8. What do you think you could have done to prevent your muscles from tiring?
9. What should you do if you experience muscle fatigue in the future?
1. It was hard because after doing the same thing, it got my hand to get tired, so it was harder to do. I also think that doing the same thing over and over ten times, was what made my hand hurt and be so tired.
2.Before the experiment, my hands felt perfectly normal and not tired or sore. During the experiment my hands got more and more tired as the experiment went on. After the first round, my hands felt pretty good. After the eighth round, my hands were very tired.
3. I don't think there is a pattern because the order in my graph starts out high then it drops and then it gets a little bit higher. But it might because it would be a pattern going up, down, up, and then a tinier bit higher. The numbers I think most of the time my graph decreases, but it is all over the place. At the beginning it drops down and then it gets tiny bit lower. Then it drops again. It comes up, and then finishes straight. Sort of straight.
4. I think it indicates that if you do something hard or tired over and over again, you will get tired the more you do it. Also, it is very likely that your scores or results will drop because you will get tired.
5. I think that my results are not very reliable. I think that I could have tried a little harder during the last couple rounds to make my results more reliable. The thing that isn't reliable about my results, is that it starts out slowly dropping, but then it raises.
6. I think that my hand strength changed because the more that I kept pinching, the more tired I got in my hand, and I think that that effected my strength in my hand.
7. I think that when you breath, eat, and drink, cells take the food and oxygen and deliver that to the muscles.
8. I think that if I took a 2 minute break, I think that my hand muscles would of relaxed and gotten more energy, so that when I started to pinch the clothespin, my hand would have more energy.
9. I will try to relax and take a break, so that I don't cause any serious damage in my muscles. I can also just stop doing whatever I am doing that is causing the muscle fatigue.
