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 model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

This is a classic exercise for visualizing the scale of the Solar System.

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

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

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