Lake Study for Macintosh is a new version of a program previously published by JCE: Software for Windows computers (1). Both the Windows and Macintosh programs are based on an Apple II program by the same name (2, 3). Lake Study is a two-part computer simulation designed to involve nonscientists with the scientific method. It allows them to collect data, formulate hypotheses, and test the hypotheses with controlled experiments in the laboratory.
Students are assigned the task of discovering the cause of breathing difficulties that are killing young fish in a lake in the first part of the simulation. They may collect water samples from the lake, analyze them, and then compare their results with library references on toxicity of the pollutants. Students may also look at the fish themselves, and consult simulated colleagues. Having done this, they can develop a hypothesis about the problem. In the second part of the experiment, students can do controlled experiments to determine which of the two hypotheses is more likely. The fact that different students reach different initial classroom discussion about the facts that support each hypothesis and their logical interpretation.

Software in Series C of JCE: Software requires an Apple Macintosh computer with a hard drive and a SuperDrive floppy disk drive. System software version 6.0.7 or later is required. If you are running System 7 or MultiFinder, at least 2 MB of RAM is required. In addition both Lake Study requires a Macintosh II or better, System 7 or higher, and at least 4 MB of RAM. A 256 color monitor is not required, but strongly recommended. Installation of Lake Study requires approximately 1,600 KB of free hard disk space.
