• Learn about water as a power source, gears, and friction with the easy to understand reference material included.
• Instead of just reading about energy or forces, the Capsela motorized building system allows you to handle interlocking parts, create motors, and see for yourself how energy changes with the help of visible gears and wheels.
• Each kit contains an easy-to-follow activity booklet introducing physical concepts such as energy changes, electric circuits, motion energy, friction and traction, buoyancy, and electric circuitry.
