Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this multi-part activity learners examine non-point water pollution.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

In this online activity, learners find out whether they are smart enough to survive as a plant.

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 on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

Build and test a scale model of a rainforest canopy walkway.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

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

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.
