Big Ideas

Units

  1. Unit 1

    Natural Selection

    Variation, inherited versus acquired traits, adaptations, and how natural selection changes populations over generations, with fossils and other evidence. Includes reading data from a predator–prey model.

    Learning standard: Evolution by natural selection; adaptation and variation; evidence such as fossils

  2. Unit 2

    Atoms & Elements

    Elements versus compounds and mixtures, chemical symbols (H, O, Na, Cl, Fe, Au…), counting atoms in formulas like H₂O and C₆H₁₂O₆, metals and non-metals, and the basics of the periodic table.

    Learning standard: Elements consist of one type of atom; compounds; chemical symbols; metals and non-metals; the periodic table

  3. Unit 3

    Circuits & Static

    Complete circuits, series versus parallel wiring, conductors and insulators, adding cell voltages, and static electricity (like and opposite charges, lightning).

    Learning standard: Electromagnetic force: electric circuits, conductors and insulators, static charge

  4. Unit 4

    Magnets & Motors

    Magnetic poles and fields, building stronger electromagnets (with a data table to extend), and how motors and generators change energy from one form to another.

    Learning standard: Electromagnetic force: magnetism, field lines, electromagnets, motors and generators

  5. Unit 5

    Restless Earth

    Earth's layers, plate tectonics, earthquakes and volcanoes, fossils in rock layers, and the order of major events in Earth's 4.6-billion-year history. Includes how First Nations oral histories and scientific evidence together date the great 1700 earthquake.

    Learning standard: Layers of the Earth; plate tectonics; earthquakes and volcanoes; fossils and geological time; First Peoples knowledge of Earth's history

  6. Unit 6

    Changing Climate

    The greenhouse effect, evidence of climate change (real CO₂ measurements, glaciers, ice cores), human causes, actions that help, and the value of Indigenous knowledge of the land.

    Learning standard: Climate change: greenhouse effect, evidence, human causes and actions; Indigenous knowledge of climate and land
