In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

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.

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

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

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.

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 archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.

In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.

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

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
