In this activity, learners explore how the hull shape impacts a ship's performance and stability.

Learners take on the role of environmental engineers as they design water filters.

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 team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

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 simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

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).

In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
