In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures. First,...

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color. First, learners use relatively simple materials to...

In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction. First, learners use relatively simple materials to construct...

In this activity, learners string a line across the room and build cable cars that can move from on end to the other. Learners construct their cable cars out of wood sticks, motors, and electrical...

In this activity, learners explore sound by constructing their very own bagpipe instrument. Learners use PVC pipe, a ziploc bag, rubber tubing, rubber bands, a plastic bottle, and a rubber glove to...

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum. This activity guide includes step-by-step instructions...

In this activity, learners build a carousel toy that spins when pushed down. Use this activity to demonstrate principles of motion including momentum, angular motion, linear motion, and cyclic...
