Epigenetic changes, caused by environmental factors, can be passed down several generations, meaning choosing to smoke can affect the life expectancy of your children and their children. Scholars explore epigenetics, learning that the phenotype of an organism can be changed without changing the DNA. The narrator discusses the three ways epigenetic works: DNA methylation, Histone acetylation, and microRNA.

Instructional Ideas

  • Have scholars further research examples of epigenetics and generational changes and present findings to the class
Classroom Considerations

  • Resource requires a computer, Internet access, and a way to project the video
  • Video assumes scholars understand phenotypes and genotypes
  • Video 10 in a series of 31

  • Fascinating topic to keep high school scholars engaged
  • Lots of interesting discussion points include nature vs. nurture, differentiation of cell types, and epigenetic changes affecting future generations

  • None
