SEMESTER ONE
Unit 1: The Science of Biology
Students explore biology as one of the sciences and confront the concepts of scientific methods. After exploring scientific processes as they apply to biology; students examine what "life" means as they investigate the characteristics that all living things share. Students then look at the importance of energy; what kinds of energy are significant when considering living things; and the relationship of structures of living things to their functions.

Unit 2: The Chemistry of Life
Students explore the chemical basis for life by examining the most important groups of organic compounds: carbohydrates; proteins; lipids; and nucleic acids. Students then examine water and how it is important for living things. In each case; students focus on the relationship of the molecular structure of compounds to its function in living things.

Unit 3: Cell Biology
Students now are able to begin looking at the structure and function of living things. They begin with an exploration of the cell. They confront the structure of the cell; its membranes and organelles. In particular; they look at the processes by which cells gather and make energy available; focusing on the activities of the mitochondrion and the chloroplast. Students then proceed to look at cellular reproduction and study the processes of meiosis and mitosis.

Unit 4: Mendelian Genetics
Students learn about the work of Gregor Mendel as a way of studying modern genetics. They perform genetic crosses and begin to see how traits are inherited. As they examine Mendelian genetics more closely; they see the relationship between inheritance and chromosomes and between genes and alleles. This unit prepares students to go deeper into genetics at the molecular level.

Unit 5: Molecular Genetics
The chemical basis for genetics is one of the cornerstones of modern biology. In this unit; students understand the relationship between DNA; RNA; and proteins—and what this has to do with genes and inheritance. After establishing a firm basis in molecular genetics; students are able to understand modern applications of genetics; including biotechnology and genetic engineering.

Unit 7: Honors Project 1: Research Paper
An independent research paper gives honors students the opportunity to explore biology topics in depth. Students select one of five topics to research and then develop a paper reporting on their topic.
Planning Your Research Paper
Finding and Using Information for Your Paper
Organizing Notes and Developing an Outline
Writing Your Paper
Creating a Works-Cited Page
Revising and Proofreading the Research Paper
Unit 8: Honors Project 2: Extended Lab: Rate of Photosynthesis
This honors project extends the Rate of Photosynthesis Lab so that students test the effects of an additional variable—light—as well as heat. Students model communication and collaboration of the scientific community by collecting and sharing data in an online shared spreadsheet. They benefit from multiple sets of data and repeated trials rather than a single set of their own data. Students download and graph the data then discuss outliers; experimental error; and other factors related to experimental design.
SEMESTER TWO
Unit 1: Gene Expression
In this unit; students explore the process by which the DNA-RNA relationship builds proteins. Then students learn how the process of proteins synthesis is controlled; a process called gene expression. Students then are able to understand modern applications of genetics; including biotechnology and genetic engineering.
Introduction
Proteins Express DNA
How Proteins Work
Gene Expression

Unit 2: Evolution
Evolution is the central organizing principle of biology. Students learn about the concept of evolution and the underlying principles of natural selection. Once they have mastered the fundamental principles; they see how modern evolution is a science that includes gene changes over time as the underlying mechanism for evolution.

Unit 3: Survey of Living Things 1
Students learn about the structure and function of living things by examining three representative organisms: a flatworm; a fern; and a human. In doing so; students examine processes such as digestion and respiration—comparing and contrasting how living things obtain food; break down food; eliminate waste; and obtain and use oxygen.

Unit 4: Survey of Living Things 2
Students continue their examination of living things; focusing on three representative organisms. They explore the nervous and muscular systems and see how these systems aid in responding to the organism's environment. Students then examine various aspects of reproduction among living things and finish with a study of defense.

Unit 5: Ecology and the Environment
As students have moved through this curriculum; they have learned about living things; their structure; and functions. In this unit; they confront organisms in relation to their environments. Students study living things and the ecosystems in which they live; examining both the biotic and abiotic components of the world in which organisms exist.

Unit 7: Honors Project 1: Virtual Lab: Antibiotic Resistance
Antibiotic resistance describes how the effects of antibiotics on certain bacteria weaken or become ineffective over time. Students investigate antibiotic resistance by conducting an experiment in the K12 Virtual Science Lab.
Virtual Lab: Antibiotic Resistance
Unit 8: Honors Project 2: Issues in Science: Online Debate
Research and technology produce new information and capabilities; as well as great responsibility. The scientific community wrestles with the question; "Just because we can; does that mean we should?" Examining all sides of an issue can sometimes bring together everyone's opinions. Other times; people just have to agree to disagree. Different sides of an issue can be examined with a debate. This project is an opportunity for students to examine current scientific issues and express opposing viewpoints through structured debate. Students work in collaborative teams to develop and present a case online. Teamwork and sharing ideas are emphasized; students meet online or in person.
