- Ice is solid water.
- Water expands when it freezes.
- Ice can be melted by heat.
- Ice can be broken into smaller pieces.

For continued development, children can experiment with different materials to freeze inside the ice, such as small toys, food coloring, or glitter. They can also try different liquids to freeze, such as juice or soda, and compare how they freeze differently than water. Additionally, children can explore the effects of different temperatures on freezing and melting times.
