Physical and chemical changes
yo dog you will see!
A physical change is when there is not a new substance.For example when you you chop wood it is still wood or when you drop a glass cup and it shatters into pieces it is glass.Basically a physical change is like when you break something but it is still it's self.Another example is ice melting when it melts it is still ice but in a liquid form.
A chemical change is when new substance is formed from like chemicals.For example metal rusting it changes.Another example burning wood it changes into ashes.Egg frying is another example.
Amazing chemical reactions!
