1.  Definitely.  At times, I wanted to put the fingers of the other hand on the clothespin, use a third finger, switch hands,  and use my whole hand to get two pieces of thin wood to touch.

2.Before the experiment, my hand felt perfectly normal, untouched.  They weren't ready for what laid ahead.  During the experiment, my hands were hurting so bad they almost fell off!  The pain was like a pang, each one lasting about 2 seconds. At some points, they actually began feeling numb. After the activity, my hands were aching, but got better by the second.

3.  My data did change overtime.  At the beginning, I wasn't tired, so the number was high in trial one.  After that, my fingers were tired, so my results went down.  As my fingers got more energy, the data I collected in the next two trials were high, but got low again.  As you can see, my diverse data made a very spiky graph!

4.  An error that most likely occurred was that a third finger "slipped" next to my index finger, which might have made my results slightly higher.  Also, the amount of time in between each 30 seconds that Mr. Solarz reset the timer may have varied, which might have resulted in higher results in a round who started in a longer break.

5.  My hand strength changed over the course of the experiment because during the 30-ish second break, it got stronger.  When I started clicking again, my fingers were strong and fast for the first couple seconds, but got weak again.  The cycle starts again when the 1-minute period starts again.

6.  Our muscles cells get oxygen when we breathe oxygen.  Our lungs give the oxygen to blood, which transmits it into the muscles.  We get water when we drink it, dirty or clean.  Water can come in the form of food, like watermelon and cucumber.

7. I think I should have taken often breaks, for the muscles to relax.  The breaks would also have given me time to breath in and out, so that my muscle cells got oxygen.

8. I should probably stop doing what I'm doing, relax and take deep breaths, and drink water.  After a few minutes, I can resume physical activity.

1.  Our model needed 3 bones, like any arm.  They were the ulna, the radius, and the humerus.  The humerus is long, although it wasn't in our joint.  The ulna and radius are shorter and thinner.  They stay right next to each other, as seen in our joint.  Our model needed two muscles, the biceps and the triceps.  A normal arm also have these two.  The biceps are on top of the arm while the triceps are on the bottom.

2.   Our muscles were similar to real muscles because they work the same way.  When the biceps contract, they pull the arm up, therefor letting the triceps relax.  They are different, though, because although our tendons fade into the bone, the model's tendons abruptly  ended when it touched the bone.

3.  If the ligaments were overstretched or torn, the whole model would fall apart.  The bones would be attached by only the tendons, which would cause the bones to slide right next to each other.

4.  Ligaments are long, stretchy strands of tissue that hold bones together at every joint.  Cartilage is a spongy material that is in between bones to prevent the two bones from rubbing together.  Tendons are the spot where muscle connects to bone.  The muscle fades into the bone, going from muscle to solid bone. 

5.  The thing that made this activity fun was the challenge.  It was just awesome that we got to get in touch with our "creative selves" and create something that made sense.

6.  This activity was challenging because of the joint.  Making a working joint was the hardest part of the model because not only did it have to be done well, but the bones kept on sliding somewhere they shouldn't be.
