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.
Outcome: CS8.1 · plant and animal cells and their parts
Unit 2
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.
Outcome: OP8.1, OP8.4 · light, its properties and electromagnetic radiation
Unit 3
Density & Buoyancy
Calculating density from mass and volume, explaining why solids, liquids and gases differ in density using the particle theory, and predicting whether objects float or sink in different fluids.
Outcome: FD8.1, FD8.2 · density, buoyancy and forces in fluids
Unit 4
Viscosity & Flow
What viscosity is, how temperature and other factors change how fluids flow, and how to find a flow rate by dividing volume by time.
Outcome: FD8.3 · viscosity and other properties of fluids
Unit 5
Pressure & Pascal's Law
Why gases compress easily and liquids do not, how heating or compressing a fluid changes its pressure and volume, and how a hydraulic press uses Pascal's law to multiply a force.
Outcome: FD8.3, FD8.4 · pressure and compressibility in fluids
Unit 6
Hydraulics & Pneumatics
How hydraulic systems (liquids) and pneumatic systems (compressed air) work, where each is used, and how valves, pumps and tubes in machines compare with the heart, lungs and blood vessels.
Outcome: FD8.4 · how hydraulic and pneumatic systems work
Unit 7
Changes to Our Water
Watersheds, the water cycle, groundwater and wetlands, droughts and floods in Saskatchewan, and the ways natural events and human actions (dams, drainage, irrigation, pavement) change where water goes.
Outcome: WS8.1 · natural and human-induced changes to the characteristics and distribution of water: watersheds, the water cycle, drought and flooding
Unit 8
Wind, Water & Ice Shape the Land
Weathering, erosion and deposition; features made by glaciers (moraines, eskers, erratics, kettle lakes), rivers (valleys, floodplains, deltas) and wind (dunes), with Saskatchewan examples such as the Qu'Appelle Valley and the Athabasca sand dunes.
Outcome: WS8.2 · how wind, water and ice have shaped and continue to shape the Canadian landscape
Unit 9
Life in Lakes & Oceans
Producers, food webs, nutrients, oxygen, light and temperature in lakes and oceans, how fishing, fertilizer runoff, dams and invasive species change aquatic life, with Saskatchewan lake examples.
Outcome: WS8.3 · natural factors and human practices that affect productivity and species distribution in marine and fresh water environments
