The perfect way to teach about the phyics of Motion and Systems in Action. This kit includes all the basic components for your students to build their own wiggler kits. These kits are motorized contraptions that move in unusual ways! You can use markers for the legs and they will leave a mark to trace their paths. OR you get your students outside into the forest to search for some perfect fallen sticks to make their own legs. You can also purchase wooden doweling (see side panel) from Kidder should you want to go that route. They are made from simple materials and set in motion by a vibrating offset motor causing them to bounce, spin, bump and move in interesting ways.
