Consists of a set of laboratory-based modules that offer a step-by-step introduction to physics and the physical sciences. Through an in-depth study of a few fundamental topics, students develop critical scientific reasoning skills. All the modules have been explicitly designed to provide practice in relating scientific concepts, representations and models to existing phenomena. Volume I introduces basic physical ideas and includes topics which represent the essential background for the study of all physical sciences. The second volume extends several subjects treated in the first and introduces additional important topics. Both books contain narrative, experiments and exercises and supplementary problems.
