Chemical changes are when a new atomically bond is created or one is broken. Physical changes are when nothing really changes, but they item changes form. Melting ice is a physical change. The ice is still water, just not frozen. Breaking glass is a physical change. The glass isn’t changing, its just in smaller pieces. Filtering a mixture is a physical change. If you filter sand from water it’s still water and sand, just not together anymore.   Burning paper is a chemical change. When you burn the paper it is no longer paper, now it’s ash and carbon dioxide.
