This week on the Conduct Science Podcast, join Mitch and Tom as they discuss earth! Not the whole planet but the dirt, soil, and rocks that are all around us! This marks the end of the somewhat silly avatar cycle for the boys and they round it out in true tangent fashion. They kick it off with some topical news and factoids before diving into what earth really is. Mitch tells us all about the spheres of earth where they both walk us through the rock cycle. Tom squeezes in his long-awaited section on volcanoes and Mitch digs up some dirt tech. Also, specially featured is Mitch’s world record attempt at the longest wind-up to a pun within a single podcast.
