Positives

• Engaging visuals accompany the narration, so students will easily follow along with the series of events depicted.
• The unusual title can be a starting point to gain student interest in the lesson.
  

Additional Prerequisites

• The video speed can be adjusted for learners at different levels.
  
• There is an ad before the video begins.
• The vocabulary is rigorous, so teachers may wish to provide a definition list or graphic organizer.
  

Differentiation

• English teachers can print the transcript and then have students highlight vocabulary words before defining them.
• More advanced students can use this video to connect to lessons about the causes of historic changes in climate, the effect of molecules such as carbon dioxide and methane on the heat balance of the Earth, and the importance of photosynthesis in the carbon cycle.
  
• Science teachers can have students work in small groups to create hard-copy timelines of the events shown on the screen, then make connections to photosynthesis, redox reactions, the chemical formula for ozone, anoxic bacteria still alive today, or other lesson topics.
