Why Lesson Planet?
What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision. Learners tape masses to fishing line and drop from different heights to determine the force required to break the line. They demonstrate the conservation of momentum with water rockets. These activities are top-notch and the lesson plans are thoroughly written for your convenience.
