Contains problematic assumptions
1) This activity does not clearly identify that it focuses on red/green color vision deficiencies (proton or deutan) which are more likely to be passed on genetically. However, while less common, there are also individuals with blue/yellow color vision deficiencies (tritan) -- which are more evenly distributed among males and females. See https://www.color-blindness.com/ for more information, tests, simulations, etc.
2) The lesson contains some rather insensitive assumptions to be shared in a middle school classroom. Would you like to be a student who has a color vision deficiency and have to experience a lesson where you and all of your classmates as told that a student who has a color vision deficiency has a reduced "probability of surviving and reproducing in a specific environment?" While making scientific thinking, it's also important to treat students with compassion and optimism. Having a color vision deficiency does result in a lesser thinking abilities or skills. Researchers in England are even developing more accurate assessments so that individuals with red/green color vision deficiencies are not automatically disqualified from certain jobs.
3) Would recommend lesson writers receive more training to better understand issues around accessibility.
