This is a cookie sitting on a plate which is a physical property, if it is cut in half it is still a physical property.
Here is another physical property, this cheese has holes in it but it i a physical property because it is still cheesse and havent't change states
Physical property is a substance that doesn't change from its orginal form
The pile of blueberries being eaten is a chemical change because it is being chewed and swallowed, Later it would no longer be blueberries after being digested
The reason for physical and chemical is to see how the things work between the two properties, physical never changes its state but chemical does changes its state to form a new substance
This is a pile of blueberries and they are being eaten by a little kid it broken down that is a chemical change, it has been broken down and digested
