Hypothisis - Explosion - Chemical change
Equipment - Sample of ZnO (Zinc Oxide)
Heat source- plate
Scales
Heat proof
Method - 1. Get sample of ` in a evaporating dish.
2. Weight the ZnO and container - record weight
3. heat container ZnO on hot plate
4. Observe any changes - use phone for before and after photos (video)
5. Take off heat and put on heat prood mat
6. Let cool - observe - photos
7. Re weigh
Results: the weight of the ZnO didn't change at all.
Conclusion:The color did change at all but when took off heat it changed so our Hypothisis was wrong.
