1. Take a long scale. Place the scale on your arm in such a way that the elbow is in the middle of the scale. Ask your friend to tie the scale to your arm. Try bending your arm now. Is it possible ? If not, why is it so?

2.Think of a earthworm (kenchua) and snail(ghongha) kept on a glass plate. Imagine how these animals reach from one place to another. What is the difference between man and the movement of these animals? Do they have bones in their body?

a) moving hand front to back

b) moving head up and down

c) moving wrist up and down

d) moving arm up and down

e) moving entire leg up and down
