Biogeochemical Skits 1. Within your group, define the key terms associated with your cycle. 2. Design a skit that shows all parts of the cycle. BE CREATIVE! 3. Your skit must include information on a. how the element is released into the atmosphere, bodies of water, in the soil b. how it is used by living things c. how the amount of the element in the cycle never changes (except the energy cycle!) d. How human activity affects the cycle e. How your cycle contributes to sustaining life on earth 4. Make skit props 5. Decide what parts people will need to play to act out the cycle 6. Perform your skit Water Cycle water water cycle evaporation condensation precipitation transpiration run-off seepage root uptake Nitrogen Cycle nitrogen nitrogen cycle proteins nitrogen-fixing bacteria decomposition run-off atmospheric nitrogen denitrification excretion Phosphorus Cycle phosphorus cycle phosphates decomposition weathering run-off nucleic acid Carbon Cycle carbon cycle carbon photosynthesis respiration combustion fossil fuels atmospheric CO2 decomposition erosion deposition Sulfur Cycle sulfur cycle sulfur volcanic emission atmospheric deposition sedimentation Energy Cycle energy cycle solar energy geothermal energy tidal energy energy degradation
