The Natural Science & Engineering students have been studying how heat energy added or removed from a system affects states of matter. We applied these ideas to learn how to solder. Each student created a ring of wire that included learning how to use wire strippers, create an in-line splice, and soldering that splice together with 99.3% Sn/0.7% Cu rosin core solder. They will use these skills next week when they build an LED flashlight which we will use to model the photoelectric effect.
