This "Tour of Basic Genetics" is an excellent interactive video to utilize in an introductory unit on Genetics. Your students could work through this on their own, or you could integrate parts of this within your instruction.
This interactive tour invites students to take a journey from the basics of DNA and inheritance to modern applications of the human genome. Students can view each step of the tour - Timeline, Code, Manipulation, Genome, Applications, Chronicle - or you could utilize only the Applications step for excellent interactive real-life applications.
