It's on Fire!
To compare physical and chemical change, we used a sheet of paper. For physical change, we wadded the paper up and unfolded it and asked the question, "Is it still paper?" Then we ripped it and asked the same question. A physical change occurs when an object changes physically, but it still remains the same object. For the chemical change, we burned the burned the paper. Don't worry, we had water on standby! We then discussed how once the paper had been burned, we could not turn it back into paper again. It was changed chemically.
