The science-oriented unit is about soldering copper pipes. This is connected to the CAVE project since it is about solder, lead’s effects on the environment, but also to the common student, since all of them have running water and some of them may have experience with soldering or one of their parents soldering. The RET grant funded soldering kits and propane blowtorches. The students first learned how to solder a joint using a soldering iron in order to introduce them to the technique and allow them to become more comfortable and mature when working with something that is extremely hot. After that, the students soldered four pieces of 3 copper pipe (one for each person in the group) with a blowtorch. The competition was for the students to create solder joints by using the least amount of solder, while also keeping the joints watertight. This correlated with CAVE’s work with industry in which research is done to make the cheapest product that is still safe and functionally dependable. The student groups were ranked according to their product. First, students’ pipes were attached to a faucet and if they leaked, they were ranked behind all others that did not leak. All of the pipes that did not leak were then ranked according to the amount of solder used. Students had to integrate some math into this set of labs as well as getting a good understanding of how business and research work together by experiencing the challenge of production.
