Description
This hands-on activity explores the concepts of density and buoyancy by testing whether everyday objects sink or float in water. Children will make predictions, observe outcomes, and document their findings, fostering scientific inquiry and critical thinking.
Details
1. Fill a clear container halfway with room-temperature water.
2. Gather 5–10 small objects (e.g., cork, coin, feather, plastic spoon, toy car).
3. Ask the child to predict whether each object will sink or float and explain why.
4. One by one, gently place each object in the water and observe what happens.
5. Discuss the results, comparing predictions to outcomes.
6. Provide paper and crayons for the child to draw or write about which objects sank or floated.
Materials
Clear container, water, small objects (cork, coin, feather, etc.), paper, crayons
