This bulletin responds to frequent requests for practical information relating to equipment and supplies for teaching science in small high schools. Laboratories for science courses have been for several decades necessary parts of every high school teaching the sciences. This bulletin is a brief survey of the necessary equipment to teach the high-school sciences according to generally accepted standards. It seems safe to say that four subjects now dominate, and that the majority of high schools with four years of sciences are now giving general science in the first year, biology in the second, and physics and chemistry in either order in the third and fourth. For the purpose of this publication, laboratory and equipment for these four universal subjects are included. The lists of furniture, equipment, apparatus, and supplies are modest and contain much less than is usually supplied in large city high schools, but they are sufficiently inclusive to cover the requirements of all the States which have fixed definite standards of laboratories and equipment for accrediting science courses.
