introductory-level biology text. Laboratory exercises begin with a list of safety issues that students need to be aware of. These items identify caustic chemicals, equipment that needs special care or handling, and health or safety hazards a careless student may encounter. We suggest that students use the laboratory manual as a workbook and record data and answers to questions in the spaces provided. The laboratory gives students the opportunity to "get involved in biology." They go beyond reading and studying and actually enter into the process of doing science.
