Spin dryer

The Dryer STEM kit offers children a hands-on opportunity to understand the principles of centrifugal force and its applications in everyday devices. As the children construct the spinning cylinder of the dryer, they will discover how rotational motion can be used to separate materials based on density. The kit illustrates how the centrifugal force acts on the droplets of water in the material, pushing them outward towards the walls of the spinning cylinder, effectively extracting moisture without the use of heat.

This process also provides a practical demonstration of kinetic energy produced by the motor, which is then transferred to the cylinder causing it to spin. As the speed of rotation increases, so does the centrifugal force, and the children can observe the relationship between rotational velocity and the force exerted on the objects within the cylinder. Through building and operating the dryer, learners will not only comprehend the mechanics of motion but also grasp the fundamental physics concepts that enable many modern appliances to function efficiently.
