A laboratory manual for one-term introductory courses in Human Biology and Biology with a human emphasis. This laboratory manual provides 33 stimulating laboratory exercises for two- or three-hour laboratory sessions in either human biology, or introductory biology courses for non-majors in which the human organism is emphasized. The level of rigor, easy-to-read text, clear procedures, and abundant illustrations make this manual especially suited for students who have had little, if any, prior science laboratory experience. All major areas of biology are covered, and the manual is compatible with any modern textbook that emphasizes the human organism.
