Interactive tutorials are blue. Student Learning Guides (SLGs) are red. 

Unit 3 sequencing notes from Mr. W.

  • It makes much more sense to learn about cellular respiration before photosynthesis, which is why Topics 3.4 and 3.6 precedes Topics 3.5
  • Topic 3.7, Fitness and Molecular Diversity, fits much better in Unit 7, Evolution.
