How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Eggshells and seashells have a lot in common. Learners use the similarities to conduct an experiment that models the effect of ocean acidification on marine animals. Using varying levels of acidic liquids, pupils make observations on the...

Examine how pollution makes its way into an ocean with help from a model watershed. Scholars use household items to recreate a mini-watershed, equipped with pollutants, that when mixed with rain drain into a model's body of...

Studying the oceans? Focus on Hawaii's ocean with a resource packed with activity-based worksheets. Everything from products that come from the ocean to the abundance of plants and animals that call the ocean their home, Hawaii's ocean...

Our oceans are composed of many complex relationships. Young oceanographers explore relationships between organisms, understand the world ocean's currents, and discover the effects of water pollution and how it behaves. There are...

Estuaries attract people—and that can mean trouble. Learners use video and article resources to learn about the struggles of specific estuaries. They follow their discussion with an analysis of an estuary by identifying possible threats.

A lab experiment, in a series of experiments, that investigates fisheries. In this lab, students test the effects of fertilizers and other pollutants on a model ecosystem. Students also examine 2 years of ocean color (chlorophyll...

Investigate the damage that ocean acidification does to the shells of sea creatures.

This large PDF file integrates math, science, and language into several lessons about characteristics of the oceans. Topics include ocean currents, tides, density, marine life, and pollution.

Students learn about oil spills and their environmental and economic effects. They experience the steps of the engineering design process as they brainstorm potential methods for oil spill clean-up, and then design, build, and re-design...

Read how freshwater moving across the surface of the Earth can become polluted and bad for the environment. Create a model that shows how water can become polluted as it flows downhill.
