In this activity, learners investigate variations in human traits. This allows learners' natural curiosity about their identity to draw them into the study of heredity. Learners can investigate traits such as earlobe attachment, tongue rolling, hair and eye color, and hair texture. Through these traits, learners get an introduction to different inheritance patterns such as simple and incomplete dominance. Activity is usually done over multiple days to give learners time to survey people about their traits. [Activity is publicly available through a web crawler capture on]
