      For Teachers

      Lizards can be excellent classroom pets, and there are many classroom activities in which you can use lizards to teach science, math, reading, writing, and more! The following activities were developed for use in fifth grade classes in Texas, as part of Trinity University’s Science Teaching Institute, to address Texas science teaching standards. We encourage you to adapt these materials in any way you find to be useful in your own classroom.
      If you are a teacher near San Antonio, Texas, and would like to invite members of Dr. Michele Johnson’s laboratory to visit your classroom, please contact us at

      This website is maintained by Dr. Michele Johnson, a lizard biologist at Trinity University in San Antonio, Texas, and the members of the Johnson Laboratory. We are scientists who study how and why lizards behave the way they do. You can learn more about the Johnson Lab at
      Michele Johnson has a Ph.D. in ecology and evolution, and the members of the Johnson Lab (called the Lizard Lab on this website) are college students. We hope this website will show how exciting it is to learn new things about lizards, and how anyone can be a scientist by looking carefully at the world around you.
