Clipboards and pencils..Introduction (5 minutes):
Discuss the concept of water absorption and its importance.
Explain that they will be testing how different materials absorb water.
Preparation (5 minutes):
Provide each student with various materials, a small bowl of water, and an eye dropper or small cup.
Explain how to use the observation sheet to record their findings.
Experiment (20 minutes):
Allow students to test each material by placing a small amount of water on it and observing what happens.
Guide them in recording their observations on the absorption observation sheets.
Sharing and Discussion (10 minutes):
Allow students to share their findings with the class.
Discuss which materials absorbed the most and least water and why.
Reinforce the practical applications of absorption (e.g., using a sponge to clean spills).
Reflection (5 minutes):
Ask students to share one new thing they learned about water absorption.
Reinforce the importance of understanding material properties in daily life.
