In this easy to implement lesson, the author shows how to teach students the rules of base pairing as well as chromosome structure. By using a variety of instructional techniques and student pairings, high schoolers learn the relationships among five important genetic terms--allele, chromosome, gene, genome, and locus. In my experience, I have found that high school learners struggle with the exact relationships among these terms. This hands-on lesson allows students to walk away with a rich understanding of the meaning of each of these terms. The author also does an excellent job showing the specific NGSS connections to the classroom activity.
