Grade 7 Science
6 units matched to the BC Curriculum.
Big Ideas
- Evolution by natural selection provides an explanation for the diversity and survival of living things.
- Elements consist of one type of atom, and compounds consist of atoms of different elements chemically combined.
- The electromagnetic force produces both electricity and magnetism.
- Earth and its climate have changed over geological time.
Units
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
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
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
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
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
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
