The mechanics by which unique individuals are built from the instructions encoded in DNA is too advanced for elementary-age children. However, students can easily understand that organisms have observable traits and that each individual has a unique combination of traits, ideas that are included in the "Next Generation Science Standards" ("NGSS") (NGSS Lead States 2013) for elementary-age students. Children are deeply curious about themselves and their traits. Elementary science teacher Ms. Anderson used a collection of fun and free activities, available in English- and Spanish-language versions, to help her students explore observable traits. In this article, she describes the activities and her experiences teaching them.
