Carolina Investigations® for AP® Environmental Science: Biogeochemical Cycles

7 Items Exclusive This product is exclusive to Carolina Biological Supply.
$5.95 - $218.25 View Details

Students study the biogeochemical cycles at work in a miniature aquatic ecosystem. They set up a gallon aquarium, then—each week—measure water loss, temperature, and levels of pH, nitrite/nitrate, phosphate, and hydrogen sulfide. They also observe and record changes in biodiversity each week. After 2 weeks, students design and implement an experiment to manipulate a parameter of the ecosystem and, in the following weeks, observe the effects on the system.
