Drugged out Daphnia Students will investigate the effects of nicotine, caffeine, aspirin, alcohol, and sleeping pills on the heart rates of Daphnia. (Objective 1. learning cycle, inquiry/experiment/investigation)
Fertilizer Frenzy Students will design and conduct an experiment testing the effect of fertilizers/soaps on algal growth. (Objective 1, 2, 4. learning cycle, inquiry/experiment/investigation.)
Evaluate Ecosystems Students will conduct an environmental inventory on one ecosystem. They will collect data, and write an environmental impact statement on that area. (Objective 2. inquiry/experiment/investigation.)
Multiplying Microbes Students learn techniques of culturing bacteria, and then they investigate environmental conditions that affect bacterial growth. (Objective 1. inquiry/experiment/investigation, learning cycle)
Endangered Species Students will graph data in order to compare the number of extinct species and a rise in human population. At first the students will not know what the data represents. They should be encouraged to infer the relationship. (Objective 4. skill-builder)
Influence of the world's ocean currents on the carbon cycle Students will demonstrate how salinity and water temperature affect the ocean's currents which in turn affect the amount of carbon dioxide available in the oceanic and atmospheric systems. (Objective 1,3. model/simulation activity)
Global Carbon Cycle This activity could be used to introduce the carbon cycle. It is an inquiry designed to model the flow of a carbon atom as it travels through the carbon cycle. Students also make connections about how human activities affect the carbon cycle. Duration: One class period. (Objective 3, inquiry activity)
