The two styrofoam cups are connected by a material to be tested for heat conductivity. The lab included aluminum rods, iron rebar, a wood stick, brass rods, copper cylinders, steel bolts, a length of lead pounded from a fishing line weight, a hunk of basalt, and any other materials we could access. Boiling water goes in the one cup, the other cup is filled with just enough room temperature tap water to cover the material in the bottom. Lynn and Marsela watch for the maximum temperature rise of the tap water. The hot water melts the glue, so a glue gun is used to repair the styrofoam cups on the fly. This is faster and safer than solvent based glues. Annnie and Clyde work on repairing their cups. In the 8:00 section I was unable to get a class discussion going.
