Kids can build and operate their own working contraptions like a robot, car, spaceship or tank---with nearly 70 parts, such as propellers, wheels and wings, and different materials, like wood and rubber. But to make the creation work, they must obey the laws of physics, which are explained in an accessible way. Engage in free play or challenges. Grade 2+
