Working muscles - A Clothespin Activity

I was unable to get the graph for this activity/blog.

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. Describe how your data changed over time.
   
4. What errors or inconsistencies might have affected your results?
5. Why did your hand strength change over the course of this experiment?
6. How do you think your muscle cells get oxygen, nutrients, and water to make the energy they need to function?
7. What do you think you could have done to prevent your muscles from tiring?
8. What should you do if you experience muscle fatigue in the future?

1. It was difficult to use the same technique the whole time.
2. Before the activity they felt fine during the activity it felt worse at times  and after they felt fine again.
3. My data changed from good to bad and then back to good.
4. Well me and my partner did the activity wrong so you could have lost track of the pinches over counted them or even under counted them because you were counting at a slow pace.
5. Because my hands got tired they became weaker at the time.
6. Through the blood stream is how muscle cells get nutrients oxygen etc.
7. I have no idea.
8. Rest maybe,  it depends what you are doing.
