We describe a field-based lizard project we did with high school students as a part of our summer Herpetological Research Experiences. We describe data collection on lizards captured, identified, and marked as a part of our mark-recapture study. We also describe other lizard projects that are ongoing in the United States and provide resources for teachers to help them start their own field-based science projects. Our work with lizards focuses on fieldwork but also includes classroom components with captive-bred and wild-captured animals. Information on organizations that focus on lizards is provided, including several citizen science opportunities.
