Using a hands-on model empowers children to visualize and comprehend complex systems. Embodied cognition principles come into play as they physically manipulate the heart model, reinforcing how blood flow works through their interactions.
1. Gather a plastic bottle, a balloon, scissors, and food coloring. 2. Cut the bottom off the plastic bottle to create a heart shape. 3. Inflate the balloon and stretch its opening over the bottle's opening. 4. Pour a few drops of food coloring into the bottle to represent blood. 5. Push down on the balloon and observe how the 'blood' pumps out of the bottle. 6. Discuss what happens to the blood when the balloon is released.
