Produced by in-print for children. Help children learn to distinguish between physical and chemical changes. This set of 12 picture cards shows everyday objects before and after a physical or chemical change, such as an egg raw and then cooked or a glass whole and then broken. Children sort the cards under two headers that tell more about physical and chemical changes.
