36 Task Card Activities

In this unit your students will observe, analyze and graph all kinds of motion: the acceleration of marbles down an incline; the herky-jerky motion of classmates doing the heel-toe shuffle; collisions of marbles with equal and unequal masses; paper clips orbiting on string; floor tappers in free fall; jet straws, catapults and much more. Thanks to Newton, all these varied motions can be understood in terms of the same basic laws. His ideas about mass, inertia, balanced and unbalanced forces, acceleration, action and reaction, all make good sense. Students grasp the abstract because they have experienced the concrete.
