In Brief: Part 1: Students watch a short video on the greenhouse effect, and answer some questions. Part 2: Students design a small model to demonstrate the greenhouse effect. Lab groups vary the gases that they test. Part 3: Students setup and take data on the greenhouse models; comparing the different groups’ setups. Part 4: Students alter their setup in attempt to reduce the greenhouse effect. Part 5: Students analyze the data, and answer conclusion questions. A. NEXT GENERATION SCIENCE...
