Ball seesaw

The Ball Seesaw STEM kit is a compelling educational apparatus that introduces the principles of gravity and motion to children. By constructing and observing the seesaw in action, they will understand how gravity acts on objects to create movement. The kit demonstrates how the force of gravity pulls the marbles down a slope, and as they reach the end, their weight acts as a lever on the seesaw mechanism, causing it to tip and deliver the marble to the next level. This repetitive motion provides a clear example of how gravitational potential energy is converted into kinetic energy.

In addition to the concepts of gravity and energy transfer, the children will also learn about the principles of balance and equilibrium. They will see that for the seesaw to function correctly, each side must be balanced in terms of weight distribution. When a marble moves and changes the weight on one side of the seesaw, the centre of mass changes, causing the seesaw to tip and restore balance as the marble rolls off. This engaging kit not only teaches young learners about fundamental physics concepts through a fun and interactive method, but it also encourages them to think about how different forces interact to create the motion we observe in many everyday objects and tools.
