Physical Properties of Matter!
By Theo Holleman
Rocks are be different. They can have holes, no holes, small, big. Very rock is different even by these simple things. Outside throw a rock at some water. You changed the how dense it is. Then throw a rock on the ground. Did it break? If it did you changed the size of the rock.
Trees can even be changed in matter! Change the how dense it is, the size, how many leaves it has!
