Grade 8 Science
8 units matched to the Manitoba Curriculum.
Learning focus
- How do the nature of the particles that make up matter influence the properties of materials?
- How does solar energy travel to Earth, and what effects does it have on the planet?
- How are organisms organized at the cellular level?
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 outcome: SCI.8.E.18, SCI.8.E.19, SCI.8.E.20, SCI.8.E.21 · the cell theory, cell structures, and cells, tissues, organs and systems
Unit 2
Heart & Blood
The heart, blood vessels and blood, how the circulatory system delivers oxygen and removes waste, and how it helps the body stay in balance.
Learning outcome: SCI.8.E.22, SCI.8.E.23 · homeostasis and the structure and function of the circulatory system
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 outcome: SCI.8.E.4, SCI.8.E.5 · the particle theory of matter, and changes of state
Unit 4
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.
Learning outcome: SCI.8.E.1, SCI.8.E.2 · density as mass over volume, and how temperature changes it
Unit 5
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.
Learning outcome: SCI.8.E.3, SCI.8.D.2 · viscosity, and testing predictions with a fair experiment
Unit 6
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 outcome: SCI.8.E.7, SCI.8.E.8, SCI.8.E.9 · solar radiation and the electromagnetic spectrum
Unit 7
The Sun, Energy & Climate
How sunlight warms Earth, why dark and bright surfaces differ, Earth's energy budget, the greenhouse effect, and photosynthesis at the start of every food chain.
Learning outcome: SCI.8.E.13, SCI.8.E.15, SCI.8.E.16, SCI.8.E.17 · solar energy, albedo, the energy budget, photosynthesis and the greenhouse effect
Unit 8
Inside Earth
The layers of Earth, where Earth's heat comes from, how tectonic plates move, and why earthquakes, volcanoes and mountains form where they do.
Learning outcome: SCI.8.E.10, SCI.8.E.11, SCI.8.E.12 · the structure of Earth, its internal heat and tectonic activity
