Look at this soft ball of dough. Can we change how it looks without cutting it or adding anything new? Hands up if you have an idea.

Watch this. I squash the dough. Press, press, flat! That is a change.

What looks different now? Is it still the same kind of dough?

Soon you will try more changes with your hands: bend, tear and stretch. Join me for a quick mime of each one.

Go to your tray. Change each material with your hands.

Try all four ways: squash, bend, tear, stretch.

See if you can find one thing that will not change.

Hands busy, no talking about it yet. We will talk in a minute.

Choose one thing you changed. Hold it up. Tell your partner the change you made: squash, bend, tear or stretch.
