Positives

• The explanations of the two biogeochemical cycles are thorough, accurate, and explained with diagrams, examples, and supporting vocabulary.
• This video helps students connect individual phenomena to a larger concept of the cycling of all matter and energy.

Additional Prerequisites

• Students should be familiar with terms related to the hydrologic cycle, including precipitation, condensation, evaporation, and reservoir.
• Students should also be familiar with terms related to the carbon cycle, including carbon, carbon dioxide, respiration, decomposition, fossil fuels, and photosynthesis.

Differentiation

• Use this video as a learning tool or review of the hydrologic and carbon cycles rather than an introduction to these concepts since it is so information-dense.
• Consider providing students with graphic organizers to diagram the stages of the two cycles.
• Pause the video often to check for students' understanding since the narrator covers many topics quickly, and consider watching the hydrologic cycle and carbon cycle portions separately rather than in one sitting.
• Before watching this video, consider setting up demonstrations and models around the classroom related to the two cycles and have students explore and connect the different phenomena to different concepts in the biogeochemical cycles.

• The video is an excellent summative tool to review the hydrologic and carbon cycles after exploring some of their respective phenomena, such as evaporation, precipitation, photosynthesis, cellular respiration, decomposition, and climate change.
