Evolution is a big idea that may be connected throughout a biology course. I also include a unit specifically focusing on evolution with my biology students, and have found CrashCourse videos to be a powerful supplement to my instruction.
This set of resources includes student worksheet for seven CrashCourse episodes that have strong connections to evolution. CrashCourse videos are excellent resources by Hank Green. They are entertaining and engaging for the high school classroom. An answer key is included for each, as well as transcripts of the programs. These videos can be used in-class or as homework.
This set includes:
Crash Course Biology #14 Natural Selection
Crash Course Biology #15 Speciation
Crash Course Biology #16 Animal Development
Crash Course Biology #17 Evolutionary Development
Crash Course Biology #18 Population Genetics
Crash Course Biology #19 Taxonomy
Crash Course Biology #20 Evolution
(If preferred, these may also be purchased through my store as individual episode worksheets.)
