Great work Max! I like how you have included an example of a physical change that is irreversible (cutting the paper into pieces and being unable to return it to a whole piece of paper). Most physical changes are reversible e.g. ice melting into liquid can be reversed by cooling/freezing back into ice. But, there are some examples of physical changes that are irreversible, like the one you have pointed out here. Ka pai! Great thinking.
