Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


 * Question:** Which muscles are stronger, flexor or extensor muscles?


 * Hypothesis:**My hypothesis is that that the extensor muscles will be stronger, because its going to be easy.


 * Procedure:**
 * 1) Get into groups
 * 2) Have one person stand up straight with his / her back against a wall.
 * 3) Have that person hold the weights in his / her dominant hand
 * 4) In a "curling" motion, have the student raise and lower the weights until his / her arms get tired.
 * 5) Repeat steps 2-4 for each member of the group.
 * 6) Record the data for each member of the group.
 * 7) Have the first person stand as straight as possible near a wall.
 * 8) Have the student hold the weights with his / her dominant arm bent near the ear.
 * 9) In a motion that mimics throwing, have the student extend the weights above his / her head until the dominant arm gets tired.
 * 10) Repeat steps 7-9 for each member of the group.
 * 11) Record the data for each member of the group.

 * Conclusion: My hypothesis was wrong because I thought my extensor muscle would be stronger but it wasn't my flexor muscle was stronger. In the whole class though the male did better in both with the flexor and extensor muscle. The male got 29.82352941 for there average flexor and the female got 27.76923077 for there average so the male did better. Then for the extensor the male got 25.17647059 for there average and the female got 20.30769231 so the male did way better.**
