In science today, year 5 explored what irreversible change would happen when an acid (vinegar) and alkali (bicarbonate of soda) were mixed together.


We had a method to follow, we were asked what caused the bag would inflate, and what would happen if we changed the size of the bag.

We had lots of fun watching the bags expand, in the hope they would cause the bags to explode. Unfortunately, the bags were too strong.
