Today we have been investigating how the shapes of solid objects made from some materials can be changed.
We looked at 4 different ways to change the shape of the object. These were:
Squashing 
Stretching 
Twisting
Before we did this, we looked at the items to make a prediction. Then we had a go at gently twisting, stretching, bending and squashing each item.
We recorded our results in a table.
What property do you think makes tea towels good for their purpose?
Why would you need to be able to squash a sponge?
When you stretch playdough, what happens to it?
