With the Leaning Tower demonstration for physical science and physics, explore center of gravity principles and learn why a tower with a low center of gravity can be tilted farther than one with a high center of gravity.
Show the connection between center of gravity and stability. With this quick and effective hands-on experiment, students explore center of gravity principles and learn why a tower with a low center of gravity can be tilted farther than one with a high center of gravity. The four different cylinders can be rearranged quickly to adjust the center of mass of the tower. Students can calculate the position of the center of mass for each new arrangement and then measure the angle at which the tower falls. Through experimentation and observation, students will recognize the condition that causes the tower to fall—when its center of gravity extends beyond its base. Instructions provided.
