CHANGES IN MATTER: PHYSICAL CHANGES

There are different physical changes in matter: mixtures, change of size, change of shape and change of state. In class we did some of them.

First, we pick up a piece of paper and apply force: the shape changes. 

Then, we place different pieces of paper together: it is a mixture.

In my thermometer we could see how the blue liquid inside got bigger: change of size.

And in our water cycle bag we could see changes of state.
