Welcome to the Change Lab! Cut a sheet of paper, and you have smaller pieces. But every piece is still paper.
That's a physical change: the form changes, but the material stays the same. Cutting, ripping, bending, and crushing are all physical changes.
A lump of clay weighs the same after you reshape it, because nothing was added or taken away.
