Children put STEM into action with our hands-on challenge kit! This engaging kit includes 5 challenge cards to prompt kids as they plan, create and test a toy basketball court. Children build the court complete with a shooting arm to launch the tethered basketball into the hoop…exploring gravity, force and motion as they go. Kit includes a wooden basketball court with a tethered basketball, a movable fulcrum wedge, 5 plastic catapult arms, 5 challenge cards and an activity card. Court measures 12" in length.
