My wish/shopping list came from Paul Robinson's Conceptual Physics: A High School Program by Paul Hewitt 1/e Lab Manual. I had tagged each lab I hoped to do, then assembled a spreadsheet list of the apparatus I would need.
And as was the case with my mechanics apparatus and materials, I began developing other labs for my students to conduct with those materials.
This is one such case. When i was in high school, Boolean logic was part of the math curriculum. Truth tables were given as homework. It was all in the textbook. Now that computer programming is huge and the world runs on integrated circuits, it seems Boole has been left behind.
In any case, my students enjoyed this activity in the 1990s and beyond. In my circuits unit, there was a series (!) of labs that groups completed in succession. Sometimes the disparity in completion times was significant. For the fast groups, "Logic Gates" allowed them to enrich their circuit skills while other groups caught up on the required lab assignments.
