INTRODUCTION
Author’s Foreword One of the greatest challenges facing instructors in any discipline is to remember what it was like before we understood the subject at hand. What were the mental obstacles we encountered on our way to understanding? What was it that we saw, heard, read, or touched that helped us make connections? What do we wish someone had said or explained? Learning styles vary, and the experiences of our lives are unique. As teachers, we struggle to explain and connect the old to the new. The sections in this instructor’s guide titled “Student Misconceptions and Concerns” and “Teaching Tips” are intended to give teachers, old and new, something to think about as they prepare and teach their course. Although these sections were written with a beginning instructor in mind, there should be something here for everyone to use. The field of biology is broad and fluid, offering new challenges in many diverse fields. For those of us with years of experience, a new twist or an opportunity to explain something in a different way can enliven our classes and refresh our efforts in the classroom. It is my hope that you will find much here to consider, to make biology more meaningful and relevant to your students. If you would like to share your insights and tips, for possible inclusion in future editions, your generous advice is most welcome and appreciated. We have so much to learn from each other.

Introduction: Biology Today
Why This Chapter Matters 1. We are living in the golden age of biology. Biological discoveries revolutionize medicine, change agriculture, and impact human culture. 2. Life is united not by a single trait, but by a common set of characteristics. Appreciating what it means to be living is as complex as life itself. 3. Life exists at many levels of biological organization. Understanding how these levels interrelate provides insight into the mechanisms of living systems. 4. The diversity of life is nested into groups that are united and interrelated by their shared evolutionary histories. 5. Science is a way of knowing and exploring our natural world. Most scientists use a combination of two main forms of inquiry: discovery science and hypothesis-driven science. 6. Understanding how science is done reveals the power and limits of this form of knowledge.
Chapter Objectives Biology and Society: Biology All Around Us 1. Describe three examples of how biology is woven into the fabric of society.
The Scope of Life 2. Describe seven properties or processes we associate with life. 3. List and give an example of each level of biological organization, starting with an ecosystem and ending with atoms. 4. Describe the two main dynamic processes in an ecosystem. 5. Compare the structure of prokaryotic and eukaryotic cells. 6. Distinguish between the three domains and four eukaryotic kingdoms of life.
Evolution: Biology’s Unifying Theme 7. Describe the two main points that Darwin made in his book On the Origin of Species by Means of Natural Selection. 8. Describe the two observations that led Darwin to his inescapable conclusion. State this conclusion. 9. Compare artificial and natural selection, noting similarities and differences.
The Process of Science 10. Compare discovery science and hypothesis-driven science. Provide examples of each regarding the study of trans fats in the human diet. 11. Distinguish between a hypothesis and a theory. Explain why natural selection qualifies as a scientific theory. 12. Distinguish science from other styles of inquiry. ..

13. Describe examples of the interdependence of technology and science.
Evolution Connection: Evolution in Our Everyday Lives 14. Explain how changes in the effectiveness of antibiotics illustrate natural selection.
Lecture Outline I. Biology and Society: Biology All Around Us 1. We are living in a golden age of biology 2. Scientists are studying a myriad of questions that are relevant to our lives a. How can errors in cell growth lead to cancer? b. How do plants trap solar energy? c. How do living creatures form ecological networks and how to human activities disrupt them? d. How did the great diversity of life on Earth evolve from the first microbes and how does such evolution have an impact on human health? e. How do mutations in genes lead to disease? f. How can DNA—the molecular basis of heredity—be used in forensic investigations?
II. The Scope of Life A. The Properties of Life 1. Biology is the scientific study of life 2. The study of biology encompasses a. a wide scale of size and b. a huge variety of life, both past and present. B. Life at Its Many Levels 1. Biologists explore life at levels ranging from the biosphere to the molecules that make up cells C. Ecosystems 1. Each organism interacts continuously with its environment a. Organisms interact continuously with the living and nonliving factors in the environment. b. All the living organisms in a specific area, along with all of the non-living factors with which they interact, form an ecosystem. 2. The dynamics of any ecosystem depend on two main processes: a. recycling of chemical nutrients and b. flow of energy. 3. Within ecosystems a. nutrients are recycled but b. energy flows through. D. Cells and Their DNA 1. The cell is the level at which the properties of life emerge 2. Cells are the lowest level of structure that can perform all activities required for life 3. All organisms are composed of cells 4. Cells are the subunits that make up multicellular organisms such as humans and trees 2
