Exoskelton of Insect

Aha! When I pull the tendon, the leg moves!

What you can learn from this activity:

Learn exoskelton and muscle system of insect by in-depth observations of human and invertebrate bodys. Moreover, Fully understand how it works by making a exoskelton specimen using a crab leg.

By giving children a question why legs and arms move though they have never thought about it, they start having an interest on it. Then, start thinking why naturally. This will give a chance to creat a habit to think themselves to take any actions.
