Physical changes are the changes you make without altering the chemical composition. You have a stick that you carve into a baseball bat shape. You changed the shape, but you did not change any chemical properties. You cut a paper into two strips. Chemical changes involve changes in the composition or you might even form something new. Any metal rusting is a chemical change. Burning wood is a chemical change. Anything that forms a precipitate or has a temperature change.
