Navigation in Scorpions

Biology Cornerstone courses offer students an in-depth hands on experience in lab research. They are designed to be a highly interactive course in which students take the lead on designing, conducting and analyzing their own research project. My course, “Navigation in Scorpions”, is centered on the navigational capabilities and sensory biology of scorpions. We build on the wealth of knowledge known from bee and ant navigation, add in our expertise of the sensory biology of scorpions and ask the students to come up with a research question, hypothesis and experimental design exploring key aspects of scorpion navigation and biology. 

We have had some great research projects, including one analyzing the ability to sense air movement from an artificial moth, sensing local changes in the magnetic field, whether or not scorpions preferred a substrate with extracts of ground up crickets over substrate with solvent only, and if they exhibited a preference for a certain substrate texture. We encourage you to click on the links below to view manuscripts each student group produced for their final exam and which we converted into a publication style format.
