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 small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners are invited to imagine the park of their dreams!

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this activity, learners explore how boats are engineered to achieve speed.

In this activity, learners construct paper airplanes that twist and turn.

Using simple, inexpensive items, learners build and test submarine models.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.

In this engineering activity, young learners investigate multi-level buildings.

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this activity, learners explore density and buoyancy as they design and construct rafts.

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

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