Changing Materials - Reversible and Irreversible changes
We decided to learn about changes in the kitchen. Sometimes when you mix materials together they make a new product. If you can get the original materials back it is a reversible change. However, if you can't get your two original materials back, that is an irreversible change.
We used vinegar and bicarbonate of soda to create an experiment. When we mixed both materials together we produced a new material. That new material was air bubbles.
