Curated OER
Newton's Second Law of Motion with Balance Toys
Students discuss acceleration and deceleration and participate in brief demonstrations of the Second Law of Motion. They apply the law to a metal balance toy and a plastic balance toy by applying the same force then with different forces.
Curated OER
Fast Cars and Roll-Over
Students creat a ramp using cardboard and tape. They follow directions to perform an experiment to determine the degree of tilt needed to cause an empty milk carton to tip over. Students discuss their results in terms of center of gravity.
Curated OER
