Physical Change:
- Boiling water
- Breaking a pencil
- Water evaporating
- Denting a car door in an accident
- Tearing paper
- Ice melting
- dissolving
Chemical Change:
- Something rusting
- photosynthesis
- metabolism/digestion
- Nuclear power [atoms are arranged differently]
- Smashing paper with two metal balls, burns paper
- Electricity in water, breaks H2O into H2 and O2

physical change is when there is only physical change occurring--and it can typically be undone easily,
whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.
