Grade 8 Science
5 units matched to the BC Curriculum.
Big Ideas
- Life processes are performed at the cellular level.
- The behaviour of matter can be explained by the kinetic molecular theory and by the atomic theory.
- Energy can be transferred as both a particle and a wave.
- The theory of plate tectonics is the unifying theory that explains Earth’s geological processes.
Units
Unit 1
Cells & Life Processes
The cell theory, what organelles do in plant and animal cells, how photosynthesis and respiration are connected, osmosis, and how cells form tissues, organs and organ systems.
Learning standard: Cells: cell theory, organelles, photosynthesis, cellular respiration and the organization of living things
Unit 2
Microbes & the Immune System
What makes something alive, helpful and harmful micro-organisms, how the immune system defends the body, how vaccines and antibiotics work, and the impact of epidemics and pandemics.
Learning standard: Characteristics of life; micro-organisms; basic functions of the immune system; vaccination, antibiotics, epidemics and pandemics
Unit 3
Particles & Matter
How the movement of particles explains solids, liquids and gases and changes of state, the parts of an atom (including the quarks inside protons and neutrons, and electrons as leptons), elements and compounds, and telling physical from chemical changes.
Learning standard: Kinetic molecular theory and atomic theory; models of the atom, protons, neutrons, quarks, electrons and leptons; states of matter, physical and chemical changes
Unit 4
Light & Radiation
Wavelength and frequency, the electromagnetic spectrum from radio waves to gamma rays and what each is used for, reflection, refraction and colour, and staying safe from UV radiation.
Learning standard: Electromagnetic radiation: types and effects; light as a wave and a particle; reflection and refraction
Unit 5
Plate Tectonics
Earth's layers and moving plates, the three kinds of plate boundaries, the evidence for continental drift and sea-floor spreading, and earthquake and tsunami safety on the BC coast.
Learning standard: Plate tectonics: evidence, plate boundaries, earthquakes, volcanoes and the Cascadia subduction zone
