Hello William, Holly and Mr. Aiston's class,Your photos of your science experiments have shown me how interesting your lesson was. I liked your conclusion. It's true, an irreversible change can't be undone. It's sort of like the way we age, we get older but we can't get younger. Aging is irreversible too. Well done!@RossMannellTeacher (retired), N.S.W., Australia
