The Traveling Psychology Fair is designed to bridge the gap between secondary and college psychology education, encourage enthusiasm for the study of psychology, enhance teaching resources for high school psychology instructors, and promote a deeper understanding of psychological principles for psychology majors. Consisting of 24 outreach activities, grouped into 12 categories, the Traveling Psychology Fair enlivens the teaching and learning of introductory psychology concepts by engaging undergraduate psychology majors in the facilitation of interactive, learner-centered activities for high school psychology students. This paper provides complete descriptions of these outreach activities. Each entry summarizes the purpose, materials, costs, time requirements, procedures, tips for engaging students, and suggested readings/websites.
