Reptiles are cold-blooded, meaning that most species of reptiles are unable to generate their own heat. This requires them to regulate the amount of heat they absorb. One method that reptiles use for thermoregulation, which is the regulation of their body temperature, is to move into the shade or water when their body temperature is high, or to bask in the sun when they are too cold and need warming up. Yet other reptiles have a different strategy; they change the coloration of their skin pigment! Contrary to popular belief, most lizards that are able to change the color of their skin, do so primarily for the purposes of regulating their body temperature, and not camouflage! In this science fair project, you will observe how the tint of a lizard?s skin helps in thermoregulation.

Note: This experiment involves causing the body temperature of the anoles to change. As reptiles require the proper temperature to digest their food, do not conduct this experiment after the anole has eaten. Conduct the experiment either before the anole has eaten or two hours after its meal. The ideal temperature for anoles is between 75 and 90 degrees fahrenheit. Observe the color of the anole?s skin when the temperature is in this range. Record your observation. You may wish to take a photo of the anole under these temperature conditions. Lower the temperature to 70 degrees by turning .....
