Diversity of Living Things

How biologists name, classify and identify the enormous variety of life, from bacteria and viruses to plants and animals, and why that variety matters to healthy ecosystems.

  2. 2Dichotomous Keys and Field Sampling
  3. 3Prokaryotes, Eukaryotes and Viruses
  4. 4Protists and Fungi
  5. 5From Algae to Flowers: Plant Diversity and Evolution
  6. 6The Animal Kingdom: Invertebrates to Vertebrates
  7. 7Biodiversity and Human Impact
Unit 2 · 5 lessons · ~20% of course

Evolution

How populations change over generations: the evidence for evolution, natural selection and adaptation, the other mechanisms that shift gene pools, and how new species form and old ones disappear.

  1. 1The Theory of Evolution and Its Evidence
  2. 2Natural Selection and Adaptation
  3. 3Mechanisms of Evolutionary Change
  4. 4Selective Breeding: Benefits and Trade-offs
  5. 5Speciation and Extinction
Unit 3 · 6 lessons · ~25% of course

Genetic Processes

How meiosis shuffles and halves chromosomes, how traits pass from parents to offspring by predictable rules, and how genetic knowledge has produced technologies that raise real social and ethical questions.

  1. 1DNA, Genes, Chromosomes and Mitosis
  2. 2Meiosis
  3. 3Mendelian Inheritance
  4. 4Beyond Simple Dominance
  5. 5Gene Mutations and Single-Gene Disorders
  6. 6Chromosomal Disorders and Genetic Technologies
Unit 4 · 6 lessons · ~20% of course

Animals: Structure and Function

How the digestive, respiratory and circulatory systems take in nutrients and oxygen, deliver them to every cell, and remove wastes, plus the disorders that affect them and the technologies used to study them.

  1. 1The Digestive System
  2. 2The Respiratory System
  3. 3The Circulatory System
  4. 4Dissection: How the Systems Fit Together
  5. 5Breathing, Circulation and Digestion Across the Animal Kingdom
  6. 6System Disorders and Medical Technology
Unit 5 · 4 lessons · ~15% of course

Plants: Anatomy, Growth, and Function

How vascular plants are built from a few tissue types, how they move water and sugar without a heart, how they grow and reproduce, and why sustainable use of plants matters to Canadian society.

  1. 1Plant Tissues and Structures
  2. 2Transport in Plants
  3. 3Plant Growth and Reproduction
  4. 4Plants, Sustainability and Society

SBI3U
Punnett Cross Lab

Pick each parent's genotype for simple dominance, incomplete dominance, codominance, sex-linked or dihybrid crosses, then compare the Punnett square's ratios with a random sample of offspring.

SBI3U
Natural Selection Lab

Run a population with a heritable colour trait against a background, set how strongly predators select, and watch the trait's frequency change generation by generation.
