Describes procedure for making X-ray photographs on Polaroid 3000 black and white roll film. (SL)

Described is the laboratory program for a second-year chemistry class at a Wisconsin high school. The laboratory stresses student-designed labs. Examples of topics considered are included. (RH)

Presented are the materials and a procedure for demonstrating the levitation of a magnet above a superconducting material. The demonstration can be projected with an overhead projector for a large group of students. Kits to simplify the demonstration can be purchased from the Institute for Chemical Education of the University of Wisconsin-Madison.…

Presents a set of laboratory experiments that can assist students in the detection of carbon dioxide. Offers a variation of the supported drop method of carbon dioxide detection that provides readily visible positive results. Includes background information on carbon dioxide. (ML)

Describes a relatively simple method of extraction and purification of bacterial DNA. This technique permits advanced secondary-level science students to obtain adequate amounts of DNA from very small pellets of bacteria and to observe some of its polymer properties. (ML)

The philosophy, structure, and organization of a chemical engineering (ChE) process laboratory are discussed. The laboratory emphasizes the oral and communication skills of students who are part of groups that resemble an industrial process research and development group. An annotated list of students' experimental projects is included. (JN)
