Build your own electrical water wheel and learn about the power of water in motion. Build the science kit and then play with the toy. For ages 8 plus. Connex is a series of educational science kits that provide useful knowledge about simple physics. Smartly designed, each Connex kit allows kids to snap the pieces together with ease and breeze. Simply snap all key components and modules together to start and pull apart once finished. Encourages kids to experiment on their own for additional learning. Best of all, each kit can snap to another to integrate functions and double (triple, quadruple) the fun.
