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.

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

• Key Terms: Hypothesis, variable, control group, data, analysis.

• Example: Measuring reaction time in different conditions to test a hypothesis.

Unit 2: Chemistry Basics / Biochemistry

This unit covers the chemical foundations of life, including atomic structure, chemical bonds, and the properties of water. Students explore the structure and function of biological macromolecules.

• Atoms and Molecules: Basic units of matter; atoms combine to form molecules via chemical bonds.

• Properties of Water: Cohesion, adhesion, high specific heat, solvent abilities.

• Biological Macromolecules: Carbohydrates, lipids, proteins, nucleic acids.

• Enzymes: Biological catalysts that speed up chemical reactions. $E + S \rightarrow ES \rightarrow E + P$

• Example: Enzyme activity lab demonstrates how temperature and pH affect enzyme function.

Unit 3: Cell Structure and Membrane Transport

This unit examines 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.

• Organelles: Nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, etc.

• Membrane Transport: Diffusion, osmosis, active transport.

• Example: Osmosis & Diffusion Lab explores how solutes move across membranes.

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: Series of phases (G1, S, G2, M) that cells go through for division.

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

• Example: Observing mitosis in onion root tip cells.

Unit 5: Meiosis & Genetics

This unit explores the process of meiosis and the principles of genetics, including inheritance patterns and genetic variation.

• Meiosis: Cell division that produces gametes with half the chromosome number. $2n \rightarrow n$

• Genetics: Study of heredity and variation; Mendelian inheritance.

• Probability in Genetics: Use of Punnett squares and probability to predict genetic outcomes.

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

Unit 6: Evolution

This unit covers the mechanisms of evolution, including natural selection, genetic drift, and speciation. Students learn how populations change over time and how evolutionary relationships are determined.

• Hardy-Weinberg Principle: Mathematical model describing allele frequencies in a non-evolving population. $p^2 + 2pq + q^2 = 1$

• 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.

• Example: Natural Selection Simulation demonstrates how traits become more or less common in a population.
