- Observation: The child observed the texture and color of the sand.
- Properties of matter: The child learned that sand is a solid and can be molded into different shapes.
- Gravity: The child learned that sand falls down when lifted or thrown up.
- Volume: The child learned that the amount of sand affects the size of the hole or shape created.
- Water displacement: If the child dug a hole close to the water, they may have noticed that the water fills the hole and displaces the sand.
For continued development, encourage the child to experiment with different types of sand, such as wet sand or kinetic sand, and observe how they behave differently. They can also explore the effects of adding water to the sand and how it changes the texture and moldability. Additionally, they can experiment with different tools, such as shovels or spoons, to see how they affect the sand and the shapes they can create.
