Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, students create samples of polluted water by mixing water with vegetable oil, dirt,...

In this physical and chemical change activity, students solve 13 clues in a crossword puzzle focusing on rates of chemical reactions and changes in the state of matter.

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class...

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Pupils investigate the biological and chemical characteristics of water to determine where purple loosestrife occurs. They create data sheets to record water quality tests in several locations and work in groups to conduct the water...
