What We As Students Can Do To Save Our World

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

Investigate the different types of pollution that storm drain runoff carries into oceans, lakes, rivers, and streams with this class demonstration. Using an aquarium and an assortment of everyday items that contaminants like motor oil,...

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson and a PowerPoint presentation...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

How safe is the drinking water you have access to? Colors, smells, and other factors may lead you to finding out if your water is safe. Watch a video that explains the ways water becomes filtered and ways to know when water is contaminated.

Students advocate for clean water.  In this water pollution lesson, students play the Peace Corps Challenge Game, discuss the effects of polluted water and write a letter to the mayor of Wanzuzu highlighting the situation of the...
