This second volume, a compilation of reprints of experimental notes in physics, was prepared by the American Association of Physics Teachers (AAPT) Committee on Apparatus and by the AAPT Executive Office in response to requests received by the Association for a completely new edition. The goal of the Committee was to provide a selection of interesting experiments to the physics teacher. Experiments were selected with several aims in mind. Among these were the desire to bring new, or not well known, experiments to the attention of the physics teacher; to introduce different, useful, laboratory techniques; and to encourage modification of existing laboratory experiments by supplying a source of ideas. This volume contains a selection of 45 laboratory experiments from these areas: mechanics, heat and sound; molecular physics; electricity and magnetism; electronic and electromagnetic waves; atomic and solid state physics; nuclear and high energy physics. Experiments useful for both low level beginning courses and advanced level courses have been included. Information concerning other publications and projects of the AAPT is detailed. (BT)
