Various objects (e.g., plastic toys, coins, corks, stones).
Large clear container filled with water.
Floating and sinking observation sheets.
Clipboards and pencils..Introduction (5 minutes):
Discuss the concept of buoyancy and what makes objects float or sink.
Explain that they will be testing different objects to see which ones float or sink.
Preparation (5 minutes):
Provide each student with various objects and a large clear container filled with water.
Explain how to use the observation sheet to record their findings.
Experiment (20 minutes):
Allow students to test each object by placing it in the water and observing what happens.
Guide them in recording their observations on the floating and sinking observation sheets.
Sharing and Discussion (10 minutes):
Allow students to share their findings with the class.
Discuss which objects floated and sank and why.
Reinforce the practical applications of buoyancy (e.g., why boats float).
Reflection (5 minutes):
Ask students to share one new thing they learned about buoyancy.
Reinforce the importance of understanding object properties in daily life.
