Today we investigated ways in which objects can change shape. We explored a variety of materials and investigated different ways in which we could manipulate them into a different shape.

We discovered that there are four main ways to change the shape of an object: squashing, bending, twisting and stretching.

We also discussed why it is useful for some objects to be able to change shape. For example a sock must be able to be stretched and bend so it can fit comfortably over a foot.
