1. Pick three students. Ask each student what happens when they

a) rolled out atta to make a roti

b) stretch a rubber band

c) Fold a piece of paper

2. Explain reversible and irreversible changes:

a) Measure the length of a piece of paper, fold it and then measure again. The shape of the paper changes. Unfold the piece of paper. It is now its original length.

b) Make a hole in a piece of paper. Ask the students to fill in the hole and make the paper as it was before. Is it possible?
