- Water freezes when it gets cold enough
- Ice is solid water
- Water expands when it freezes
- Objects can get stuck in ice
- Ice can be melted to turn back into water
For continued development, the child could try freezing different objects in water and observing how they react. They could also experiment with different temperatures and see how it affects the freezing process. Additionally, they could explore the concept of buoyancy by freezing objects of different weights and observing how they float or sink in the ice.
