Educator Guide: Lava Lamp Star and Glowing Bat Toes

Biologists didn't design their experiments looking for glow-in-the-dark feet, but sometimes scientific failures yield surprising discoveries. If glowing toes sound batty to you, learn how scientists illuminate the secrets of a flighty mammal while answering questions about the scientific process.

For astronomers, watching convective cells of gas move on the surface of a distant star was kind of like looking at a lava lamp. Begin a unit on energy transfer by having students discuss lava lamps and the process of convection at work in them. Then have students read about the first observation of convection on a distant star and its potential scientific importance. Finally, students will brainstorm and diagram other examples of devices or natural processes that involve convection.
