In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners explore how watermills have helped harness energy from water through the ages.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

In this geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

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, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.
