This short video on DNA is an overview of the details of what DNA is, and what can be done with it. The video goes from explaining the correlation of DNA and genetic material, to comparing it with other living things, to Genetically Modified Organisms. While GMOs are a very controversial subject, this video simply gives the positives of what may be accomplished, and the negatives of the unknown.
This video would be a great opening to a segment on DNA, or more specifically on GMOs. This video is about as unbiased as possible, giving the potential positives and negatives of GMOs. A great activity would be to divide your class into pro and anti GMO, ignoring personal feelings of your students. Have your students gather information in support of or against research into GMOs, and debate whether it should be continued, and if so, how. While this may not help lead to students changing sides, it will lead to more knowledgable students.
