Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

What sort of shoes do frogs wear? Open toad sandals. If your scholars want experience collecting field samples, this is the lesson plan for you. After learning the proper way to collect field samples, pupils catch amphibians to test for...

Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

What's in your water? And, why is water quality so important? Enhance your class's level of water appreciation through a lesson that demonstrates the necessity of water quality. Environmental enthusiasts explore the EPA's Clean Water...

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

In this worksheet for making standard solutions, learners read about making a standard solution and perform the three background calculations necessary to make one. Students then make a solution by weighing a given substance, adding it...

In this pollution worksheet, students read about how air pollution is created and the harmful products from car exhausts. Then, they complete nine short answer questions.
