Lemke et al: Physical Geography Laboratory Manual is a comprehensive introductory manual for students without a previous science background. An abundant set of 21 exercises assures that every professor will find a complete set of preferred labs for a semester-long course. Lemke/Ritter/Heywood wrote this lab manual in order to provide equal coverage of the four spheres of the environment—the atmosphere, biosphere, hydrosphere, and lithosphere. The lab manual was written independent of any specific textbook and will work with available physical geography texts.
