Physical or Chemical Change

                   (Heating ZnO)

 Hypothesis- Explosion = Chemical change

Equipment - Sample of ZnO (Zinc oxide)

• Heat source - Hot plate
• Scales
• Heatproof container - Evaporating dish
• Tongs
• Heatproof mat

Method -   

1. Get sample ff Zn0 in an evaporating dish
2. Weigh the ZnO + container - Record weight
3. Heat container + ZnO on a hot plate
4. Observe any changes - use the phone for before and after photos (Video?)
5. Take of hot  + put on a heatproof mat
6. Let cool - observe - Photos
7. Re weigh

Results -

The result is the zinc oxide was change colour to light yellow and it has different smells

Conclusion - 

First, we have to get zinc oxide and turn on the  Heat were we going to put the zinc oxide so that where we can see what it changes if its smell different or like changes colour,  First we have to measure the weight of the zinc oxide then after that we have to put it in the hate so we can see what the changes are.
