    1 - Getting Started ~3 mins

    The dough the class will change today, shown plainly and closeLook 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.

    2 - Four Ways to Change ~4 mins

    Four dough pieces showing what squashing, bending, tearing, stretching leave behindWatch 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.

    3 - Changing Trays ~12 mins

    The tray of materials each child will handle, so they know what to expectGo 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.

    4 - What Stayed the Same? ~5 mins

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

    5 - Who Changes Materials? ~4 mins

    Real objects made by squashing, bending, folding and tearing materialsLook at this little pot. Someone squashed and bent clay to make it. Look at this card. Someone folded and tore paper to make it. We changed materials with our hands too.

    Which change did the pot need: squash, bend, tear or stretch?
