I love blogging about our successes.... you know bragging for educational purposes.... but this post is not a brag... read on.....
We made, or at least tried to make a model of the arm. The point of the model was to show how the muscles re-act when the arm is extended or bent at the elbow.
We rolled up our tubes of newspaper (3 of them).....
Then proceeded to punch (push, pull, tug and more) holes into the ends of the tubes of newspaper...
Then there was a whole bunch if finagling .... we were supposed to attach one tube to two others with a giant paper clip (I used 22 gauge wire).. then, attach two balloons, slightly inflated, to the top of the single tube. Then, stretch the balloons just past the hinge, add a hand and voila!
No Voila.......
The darn balloons, inflated or not (we tried both ways) would not for the life of me stretch across the newspaper tube without bending it in half. We tried a few different ways and got frustrated so I just held on to the balloons and showed the boys what was SUPPOSED to happen and they did get the jist of it all, but phew! how hard was that?
I guess we could redo the whole thing and use stronger tubes of some sort...but do we really want to?
