Coral Bleaching

Positives

• The animation starts from a satellite image of the Earth and zooms all the way in to see the inner workings of an individual coral and its symbiotic algae cells.
  

Additional Prerequisites

Differentiation

• It may be helpful for students to pause the animation at various points to discuss specific parts of the corals or algae, as well as different steps in the process.
• The teacher could ask advanced students to use the video as a basis for a presentation of their own to explain the coral bleaching process to their classmates.
  
• After watching this video, students could graph and analyze ocean temperature data for coral reef sites around the world.
  
• This would be an excellent animation to accompany lessons about photosynthesis, cellular respiration, organelles, cells, symbiotic relationships, heat energy, ocean ecosystems, and chemical reactions.
  
• Other recommended resources include Resistance to Coral Bleaching and Interactive Exploration of Coral Bleaching.
