In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

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 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.
