REQUIRED TEXTBOOKS AND COURSE MATERIALS

Required Textbook: Reecy and Urry. Biology Lab Manula. Pearson Collections

DESCRIPTION

An introductory laboratory course focusing on scientific inquiry and investigation of cell and molecular biology principles, use of laboratory equipment, and metric system measurements and conversions.
Pre- and post-lab activities: Labs are an opportunity to gain hands-on experience with the theories, organisms and processes that we discuss in lecture. To prepare you for each lab, you will complete a short pre-lab quiz that will evaluate class reading of the lab's goals and tasks.
Post-lab assignments will assess your understanding of key observations and concepts covered in the lab activity and connect them to lecture content. Pre-lab activities will be completed individually on Collab, while post-lab activities will usually be completed as a group and handed in at the end of each lab activity.
