Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
