This laboratory manual is designed for an introductory biology course with a broad survey of basic laboratory techniques. The experiments and procedures are simple,safe,easy to perform,and especially appropriate for large classes. Few experiments require a second class-meeting to complete the procedure. Each exercise includes many photographs,traditional topics,and experiments that help students learn about life. Procedures within each exercise are numerous and discrete so that an exercise can be tailored to the needs of the students,the style of the instructor,and the facilities available. New to this edition is a Web Site. What we've done is this: Each lab in the manual will have icons indicating what types of activities students will find on the web site. There will be icons for: Essential Study Partner modules,Animations,Activities,Readings,Math Help,BioCourse. Com,and a special password protected section for Instructors that will house the Lab Resource Guide,alternative recipes for lab solutions,and more.
