In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

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

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

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.

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 collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

In this activity, learners make a device called a phenakistoscope, which displays a continuously looping animation consisting of images drawn onto a spinning disc.

This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

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 outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
