You may have dreamed about driving a train when you were little. Shawn visits an Amtrak station and learns what the career of a train engineer is really like. Like looking at slides under a microscope? Gracey will visit a lab where she talks to a histologist and see what he’s looking for as he examines those slides. Then Shawn will go to a resort and learn about the team that designs and builds those inviting and extravagant pools where guests spend hours playing and relaxing.
