Week 1: Introduction to the Science of Biology
Imagine you are beginning your daily late afternoon jog on a wooded path near your home. As you begin your long strides, you breathe in the crisp air, feeling your leg muscles stretch and your heart pound. You look around and notice that leaves on the trees are beginning to change color. A squirrel scampers through the grass to your right. A startled deer on the left raises its head, staring briefly at you before turning to run with its white tail bobbing behind. This may be a daily routine, but it is an exhilarating experience. It feels great to be alive and experience nature.
You may not take much time to think about the life in your body or the life around you, but it is there, and it is amazingly complex. Biology is the science that studies life, and it would have a lot to say about the scene described above. This week, you begin to explore biology and the process of science. You learn what the scientific method is and how scientists use it to learn more about the nature of life. You also begin to learn about the building blocks of life.
Note that this course contains three different graded assessment items in addition to Discussions and Assignments. Each week, you complete a 10-question Self-Assessment Quiz and a 20-question Weekly Exam. In Week 6, you complete a 60-question Final Exam that covers content for the entire course.

This chapter provides a basic description of scientific inquiry and identifies influences on this process, such as societal values and public opinion. The author emphasizes that science is a systematic process for gaining knowledge about patterns in all of nature and that science is not a process applied to gain knowledge in all areas, such as philosophy or the supernatural. (Science is technically an offshoot of philosophy, originally called Natural philosophy.)

This resource defines six criteria to use to distinguish science from non-science: consistency, observability, natural, predictability, testability, and tentativeness. Readers are challenged to distinguish between scientific and non-scientific statements.
Document: Osmosis Lab Instructions (Word document)
This document contains instructions for the Osmosis Lab you complete for your Assignment this week. Note: The Cell Structure and Function Virtual Lab may assist you in understanding the Osmosis Lab. You must also start this Osmosis (at-home) Lab by Day 3.

Assignment: Biochemistry and Cell Biology
Imagine you are making plans to take care of your home as you prepare to leave for a long vacation. You realize there are two things in your home that require special attention: your pets and your houseplants. These need special attention because they are alive. Have you thought closely about what distinguishes a living organism from a non-living thing?
“Biochemistry is the study of the structure, composition, and chemical reactions of substances in living systems” (American Chemical Society, 2012). This week, you begin to explore biochemistry as you learn about the fundamental unit of all living things—the cell. You discover what all cells require for life, learn about the cell’s structure and how it functions, and pay special attention to a critical cell component, the cell membrane.
For this Assignment, you complete the Cell Structure and Function Virtual Lab and complete a hands-on lab about cell function, the Osmosis Lab. You also complete and submit a lab report based on the Osmosis Lab.

To prepare for this week’s Assignment:
Review Chapter 2, “Science Fiction, Bad Science, and Pseudoscience” to learn about the cell and the basic requirements of all living things.
Review Chapter 3: “Is It Possible to Supplement Your Way to Better Performance and Health” Section 3.3 Transport across Membranes (pp. 61-64) to learn about cell membrane structure and how molecules pass in and out of the cell.
