In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.

In this activity, learners build magnetic towers to explore the forces and properties of magnets.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this activity, learners make a flip book that shows the progression of two solar events on reversible sides of the flip book.
