Do Salt Water Fish Drink?

Whether you're a salty sea dog or a total land lubber, the lakes and oceans of our world have a tremendous impact upon everyday life. Module six in a seven-part series of lesson plans centered on fresh and saltwater literacy tackles some...

In this Hudson River worksheet, learners read about fish communities in the river and complete related graph and comprehension activities.

How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use a potato...

Students discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers science...

Why do sharks swim in salt water? Because pepper water makes them sneeze! An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from...

The key to curing cancer could be swimming around in your aquarium! Young biologists meet the zebra fish and learn about its contributions to medicine in the 149th installment in a series of science videos. The content includes how fish...

Most of the water on Earth is found in our oceans; however, humans cannot survive on salt water. Instead, we need freshwater. So, what is freshwater and where does it come from? This is the focus of a video that discusses the differences...

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 how force works to propel rockets into outer space. In this physics lesson, students use a drinking straw, fishing line, a balloon, and tape to explore how force works in outer space. Students repeat the experiment...
