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 design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

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 activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners explore how nanosized structures can create brilliant color.

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 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 engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

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

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

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.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

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

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

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