Do Salt Water Fish Drink?

What does the ground around your home have to do with water pollution? Young ecologists learn about their local watershed and create their own cause-and-effect models of the hydrosphere.

There must be a catch! A comprehensive lesson looks at ocean fishing concerns through a set of five hands-on activities. Learners become aware of the risks of seafood contamination and factors that have affected the ocean environment.

The ocean may seem a world away, but you can actually find it in a science classroom! Learners in the lower grade levels explore the concepts of water pollution, apex predators, the worth of animals, and commercial fishing methods. High...

Your teenagers may have heard of fracking, but do they really know what it is? And could they debate the benefits and risks? Educate your environmental science class with a lesson about hydraulic fracturing, non-renewable energy sources,...

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions about...

Immerse your chemistry class in solutions! They melt and compare the mixtures that make up margarine, separate black ink into its component colors, distill ocean saltwater, and practice chromatography with plant pigments. There are eight...

Because salmon live both in salt and freshwater, they have physical (different urine concentrations) and behavioral (drinking more or less water) adaptations to maintain osmolality. In this osmoregulation video, the instructor reviews...

Students investigate the water cycle by viewing an online video.  In this drinking water lesson, students create solar stills at their campus in order to purify water that is tainted.  Students view a video on their computers about...

There is plenty of talk these days about our carbon footprints, but what about our water footprints? Do we think much about the amount of water we use in a given day or how safe it really is? Raise awareness with this resource. A...
