Flexor+and+Extensor+Muscles


 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:** I think that the extensor muscle is stronger, because you are all was reaching for things and picking up things.

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.
 * Procedure:**


 * Data:** [[file:flexorextensor205.xls]]

|| 20 || || 25 ||  || 7 ||  || 17 || My hypothesis was incorrect. I was incorrect because the average of the Flexor muscle was 28.93 and the Extensor muscles average was 23.1. As you can see with the data I just showed you the Flexor muscles was higher then the Extensor muscles average.
 * **Group Member** || **Flexor Muscle (curl)** || **Extensor Muscle** **(extend)** ||
 * girl 1 || 26
 * girl 2 || 25
 * girl 3 || 27
 * girl 4 || 26
 * Conclusion:**
