In Motion
and Design, student teams create
vehicles from K'NEX building pieces and use them to explore
effects of force, friction, and wind resistance on distance
and speed.

In various experiments, students use
washers as weights to quantify the force applied through a string to
pull their vehicles, and they use wood blocks to quantify a vehicle's
load. In addition to weights, the teams use propellers and rubber
bands to propel their vehicles, so they observe the forward reaction
caused by forcing air backward.
After exploring basic concepts of motion, the
teams design vehicles to meet specifications and then they test the
vehicles. Students practice developing their designs within the
confines of cost and availability of materials. They also get
practice in mechanical drafting, through both following and
developing two- and three-view drawings of vehicles.
