The Bell Solar Energy Experiment Kit developed by Purdue alumnus, William E. Taylor, was one of the kits designed for classroom use by students who had demonstrated high scientific aptitudes. Program materials were distributed to high schools by the local Bell System telephone companies. The pamphlets, books and manuals that came with the kits were written by Bell Telephone employees who had Ph.Ds.  The pamphlet in this kit was written by D.M. Chaplin.
