Suzi Serengeti and Rob Nelson have decided to visit the Cedar Creek Natural History Area in Minnesota to examine why grasslands exist in this area instead of other biomes. During the process they run into CCNHA researchers Ramesh and Erin. They quickly explain some of the reasons why grasslands are dominant in this area. Then they show us a few of the experiments that exist around the main facilities.

Hazen Audel (snake wrangler and biologist) and Rob Nelson (filmmaker / biologist) have teamed up with Ecogeeks to explore the world of deadly snakes. In this episode we travel to Washington State University to visit Dr. Ken Kardong. He explains that determining the deadliest is tricky. There really is no way to determine one deadly snake, but we show you what factors are involved in making predictions.
