This lesson helps students prepare for these Next Generation Science Standards Performance Expectations: Demonstrate, explain, and predict how a stronger push or pull can create a bigger change in an object's motion.Demonstrate, explain, and predict how pushes and pulls can start, stop, or change the direction of an object's motion.Categorize actions as either pushes or pulls.This lesson can be expanded with a second lesson exploring how objects can push each other, and how weight influences motion. They throw balls, play with toy cars, and sweep the floor, but how much do they think about these actions? In this fun, hands-on lesson, you will use a game (rolling balls) to explore how pushing and pulling affects an object's motion. Your kindergarten students are used to moving objects.
