Part two of the first year in the Portland Project, a three-year high school integrated science curriculum, is contained in this student guide. This volume, one of four parts in the year course, involves activities relating to what is considered the most powerful unifying concept in science: energy. The macroscopic aspects of heat as embodied in…

This manual is intended as a reference. Teachers who use it should select the materials best suited to their work. The first part of the manual is devoted to the sense of sight, for that is of fundamental importance in understanding why certain practices are recommended. The next section presents the principles of light control and of lighting for…

The purpose of this study was to design a beginning course in geology which not only accents the sociological implications inherent in the study of geology, but also presents the learner with the opportunity to solve geological problems by using laboratory techniques. A curriculum rationale was designed in which those environmental problems with…

The first trial version of a unit of the Australian Science Education Project materials for grades seven through ten in Australian secondary schools is intended for students in the concrete operations stage of intellectual development. It provides activities to give students a broad introduction to the concept of energy, which is treated as a…

This booklet is one in a series of instructional aids designed for use by elementary and secondary school science teachers. First, the original natural scene of the eastern portion of the United States is described, from the Atlantic Coast to the Mississippi River, as it probably was before European man invaded in great numbers. How local…
