We discussed what we were going to do and then drew up our prediction. We then put on protective goggles and gloves.   We discovered that when  you mix  bicarbonate of soda  and vinegar “the egg melts” and “fizzes.” Did we predict correctly?    Some of us thought it would hatch or disappear and some of us thought it would change colour.  We then drew up our experiment results. Some good predictions! We then found some  toy dinosaurs inside.
