So much Fun! My students were a little skeptical when I started talking about this challenge.
Turns out- they loved it! (I think their skepticism was in not understanding what we were building!)
And then they learned so much. That’s a win-win for me (and for them). So, as always, let me share a few things- especially four things to absolutely avoid when you try this.
I am almost always guilty of trying things and I have no idea what’s going to happen. Now, I don’t mean things like jumping out of an airplane (although I have done that)- just the small things in the STEM Lab. I invent the challenges and we try them.
- Pre-teach. Pre-teach. Pre-teach.
- Stuff the plastic hands first.
- Tying knots is hard.
- Allow enough time!
I gave them these instructions:
- Hold your hand out in front of you with your palm facing outward.
- Use the other hand and lightly place a fingertip on the first tendon- below your pointer finger.
- Now, curl your pointer finger. (They should be able to feel and see the movement of the tendon.)
- Now, keep your hand in front of you and place your fingertips on the muscle in your forearm.
- Curl all of your fingers into a fist. (They should be able to feel the muscle movement and see the tendons move in their hand.)
In the photo above look at the hand that is all blue. On the fingers of that hand, the straws represent the finger areas and the tendons that lead from the hand to the bones of those fingers.
Stuff the Hands First
