In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners become detectives and use chemistry to investigate fingerprints.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

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

In this engineering activity, learners design and build a mechanical arm to lift a small item.
