Why It Works

The learning connection

Hands-on experiments make abstract concepts tangible and relatable. By actively engaging, students retain knowledge better and develop critical thinking skills.

Extend the Lesson

Try it with your learner

1. Fill the large container with water until it's half full. 2. Mark the water level on the container with a marker. 3. Carefully place the small object into the water and observe the new water level. 4. Use the measuring cup to measure the amount of water displaced. 5. Remove the object and measure the original water level again. 6. What did you notice about the water levels before and after placing the object?
