Follow the Drop
Young surveyors look for patterns in water flow around campus. Using a map of the school (that you will need to create), they mark the direction of the path of water. They also perform calculations for the volume that becomes runoff. The...

Science Buddies: Using Daphnia to Monitor Water Toxicity
In a bioassay, a living organism serves as a detector for toxins-the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay...
