Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:** My hypothesis is that the flexor muscle is stronger because you can pull more with your flexor than pushing with your extensor.


 * 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.
