Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

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.

The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.
