Introduce the gravity theme to your students. Ask if they have heard of gravity, and write down what they already know. Read an age appropriate nonfiction book that illustrates the effects of gravity.
Explain gravity in simple terms. Tell students that gravity is what keeps their feet on the ground. Ask them to imagine what the world would look like without gravity.
Perform outdoor gravity experiments throughout the week. Bring objects of different weights, and have students drop them from different heights. These objects could include handkerchiefs or scarves, large and small balls, air filled balloons or balloons filled with rice.
Ask students to predict which objects will reach the ground first and why. Write down their responses. Encourage students to choose their own object pairs to experiment with.
Provide gravity-related toys in different areas of your classroom. This could include a car ramp, bouncy balls, bean bags or juggling scarves.
Review what students learned. As a class, come up with a cohesive definition of gravity and how it affects life every day.
