Unit Summaries and Key Concepts

Unit 1: Scientific Method / Academic Vocabulary

This unit introduces the foundational principles of scientific inquiry and essential terminology used in biology. Students learn how to design experiments, analyze data, and interpret results using statistical methods.

• Scientific Method: A systematic approach to investigation involving observation, hypothesis formation, experimentation, and conclusion.

• Chi Square Test: A statistical method used to determine if observed data fits expected outcomes. $\chi^2 = \sum \frac{(O - E)^2}{E}$

• Academic Vocabulary: Terms such as hypothesis, variable, control, and theory are emphasized.

• Lab Example: The Skittles Chi Square lab applies statistical analysis to real data.

Unit 2: Chemistry Basics / Biochemistry

This unit covers the chemical foundations of life, including atomic structure, chemical bonding, properties of water, and the basics of biochemistry such as macromolecules and enzyme function.

• Properties of Water: Water's polarity, hydrogen bonding, and its role as a universal solvent.

• Macromolecules: Carbohydrates, lipids, proteins, and nucleic acids are discussed in terms of structure and function.

• Enzyme Activity: Enzymes are biological catalysts that speed up chemical reactions. $\text{Enzyme} + \text{Substrate} \rightarrow \text{Enzyme-Substrate Complex} \rightarrow \text{Product} + \text{Enzyme}$

• Lab Example: Enzyme Activity Lab explores how temperature and pH affect enzyme function.

Unit 3: Cell Structure and Membrane Transport

This unit explores the structure and function of cells, including organelles and the mechanisms by which substances move across cell membranes.

• Cell Theory: All living things are composed of cells; cells are the basic unit of life; all cells come from pre-existing cells.

• Membrane Transport: Includes diffusion, osmosis, and active transport.

• Surface Area to Volume Ratio: Influences cell size and efficiency of transport.

• Lab Example: Osmosis & Diffusion Lab demonstrates passive transport mechanisms.

Unit 4: Cell Life Cycle & Mitosis

This unit focuses on the stages of the cell cycle and the process of mitosis, which is essential for growth and repair in multicellular organisms.

• Cell Cycle: Consists of interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

• Mitosis: Division of a cell's nucleus resulting in two genetically identical daughter cells. $\text{Stages: Prophase} \rightarrow \text{Metaphase} \rightarrow \text{Anaphase} \rightarrow \text{Telophase}$

• Lab Example: Observing Mitosis in onion root tips.

Unit 5: Meiosis & Genetics

This unit examines the process of meiosis, which leads to genetic diversity, and the principles of inheritance as described by Mendelian genetics.

• Meiosis: Cell division that produces gametes with half the chromosome number of the parent cell.

• Mendelian Genetics: Laws of segregation and independent assortment.

• Probability in Genetics: Used to predict outcomes of genetic crosses. $P = \frac{\text{Number of desired outcomes}}{\text{Total number of possible outcomes}}$

• Lab Example: Genetics Probability Lab uses Punnett squares to model inheritance.

Unit 6: Evolution

This unit explores the mechanisms of evolution, including natural selection, genetic drift, and speciation, as well as methods for classifying organisms.

• Hardy-Weinberg Principle: Describes genetic equilibrium in populations. $p^2 + 2pq + q^2 = 1$

• Natural Selection: Process by which organisms better adapted to their environment tend to survive and reproduce.

• Cladistics: Method of classifying organisms based on common ancestry.

• Lab Example: Natural Selection Simulation models evolutionary change.
