Course Outline

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.

  • Introduction
  • Biology and Scientific Methods
  • Scientific Processes
  • Laboratory: Using a Microscope
  • The Characteristics of Life
  • Energy and Life
  • Structure and Function

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 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.

  • The Work of Gregor Mendel
  • Mendelian Inheritance
  • Laboratory: Genetic Crosses 1
  • Pedigrees
  • Laboratory: Gene Mapping
  • Chromosomes and Genes

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.

  • DNA, RNA, and Proteins
  • Structure of DNA
  • Structures of RNA
  • DNA Replication

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
  • Biotechnology
  • Genetic Engineering

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.

  • Evolution and Biology
  • Evolution of Populations
  • Multiplying Variation in Populations
  • Types of Natural Selection
  • History of Evolutionary Thought

  • 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.
