I show this 45 minute documentary during my Nature and Nurture unit for psychology but it could also be used in various science courses, like biology. The video covers epi-genetics and how we inherit certain genes from our parents that could be linked to a famine they experienced in their life time. It is a great video for discussions. After watching this video, I have had 2 students go and major in genetics in college.
Video guide is 6 short answer questions that are easy to answer if they are watching the video.
