This video from Nature offers a description of desirable traits in beef and dairy cattle.

In this video segment from Nature, learn about six different breeds of cattle.

Students will read and evaluate different perspectives related to the Green Revolution and analyze how different perspectives can shape the public´s perception of agriculture and biotechnology.  Students read different articles written about the Green Revolution and answer questions to encourage them to interpret the meaning behind each article.  I use small and large group discussions after students read the articles to also stimuate discussion in my classroom about perceptions of the public.  You can extend this activity by having students conduct surveys or additional reseach about more recent topics related to biotechnology and find other articles that showcase different sides of an issue.  

This class provides a historical survey of the ways that people have interacted with their closest animal relatives, for example: hunting, domestication of livestock, exploitation of animal labor, scientific study of animals, display of exotic and performing animals, and pet keeping. Themes include changing ideas about animal agency and intelligence, our moral obligations to animals, and the limits imposed on the use of animals.
