The Cleaning Station

A referenced PowerPoint is not included, but this lesson can still make an impact with emerging environmentalists. After introducing them to the facts about overfishing, they experiment with a fishing simulation using colored beads and...

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

When your environmental or earth science class is studying air pollution, you will want to take the time to go over this resource. Pupils peruse the history of air pollution regulations and examine outstanding diagrams of what...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

Young scientists create their very own aquifers in this science lesson on ground water. After learning about how some people get their drinking water from underground wells, young learners use sand, modeling clay, and aquarium rocks to...

Today very few animals exist with both an endoskeleton and exoskeleton. Yet, in the Devonian period, a large number of fish species lived with both. Scientists debate if they were for protection or mineral storage, because none of them...

Many species find breathing a convenient way to survive. The PBS Eons series explains how fish learned to breathe air. It details what scientists know about evolutionary history as well as many species that developed this skill...

A fish is not just a fish. So many fish in remote places have unique characteristics. Take a trip with an ichthyologist to the Congo River to discover the species of one of the most diverse fish populations in the world. The online...

Have you ever wondered how to paralyze a fish? The cone snail produces venom that works, but what happens at a molecular level? A calcium channel blocker prevents muscle movement, enabling the slow-moving snail to catch faster, larger...
