Grade 8 Science curriculum practice

Life systems, matter and energy, structures and mechanisms, and Earth and space practice based on the Ontario Science and Technology Curriculum. Brightwick breaks the roadmap into short, focused goals that children can practise independently and revisit when a concept needs more time.

Science strand

Life Systems

Cells: The Basic Unit of Life

The tiny units all living things are made of, and how we see them.

Learning goals

All Living Things Are Made of CellsState the main ideas of cell theory: all living things are made of cells, and cells come from other cells.
Parts of a CellIdentify the main cell parts — membrane, cytoplasm, nucleus, and mitochondria — and the job each does.
Plant Cells vs Animal CellsCompare plant and animal cells, including the cell wall, chloroplasts, and large vacuole found in plants.
Seeing Cells: The MicroscopeDescribe how microscopes magnify cells and how the microscope led to the discovery of cells.
Single-Celled OrganismsDescribe organisms made of one cell, like bacteria and amoebas, and how they carry out all life processes.

From Cells to Systems

How cells move materials, multiply, and team up to build a whole organism.

Learning goals

Diffusion and OsmosisDescribe how substances move into and out of cells by diffusion, and water by osmosis.
Cells DivideExplain that organisms grow and repair themselves because cells divide to make new cells.
Specialized CellsDescribe how cells like nerve, muscle, and red blood cells are specialized for particular jobs.
Cells, Tissues, Organs, SystemsOrder the levels of organization in living things from cells to tissues, organs, and organ systems.
Cells and HealthDescribe how understanding cells helps medicine, from fighting infections to studying diseases.

Science strand

Matter and Energy

Properties of Fluids

How liquids and gases flow, float, and behave — explained by particles.

Learning goals

What Is a Fluid?Identify liquids and gases as fluids because they flow, and give examples of fluids in daily life and industry.
Fluids and the Particle TheoryUse the particle theory to explain why fluids flow and take the shape of their containers.
Viscosity: How Fluids FlowCompare the viscosity of fluids and describe how temperature changes how easily a fluid flows.
Density: Will It Float?Describe density as mass per unit of volume, and use it to predict whether something sinks or floats.
BuoyancyDescribe the buoyant force fluids exert on objects, and how ships and submarines use it.

Fluids Under Pressure

Pressure in liquids and gases, and the hydraulic and pneumatic systems it powers.

Learning goals

Pressure in FluidsDescribe pressure as force spread over an area, and how fluid pressure acts in all directions and grows with depth.
Squeezing FluidsExplain why gases can be compressed but liquids barely can, using the particle theory.
Hydraulic SystemsDescribe how hydraulic systems use liquids to transmit force, as in car brakes and lifts.
Pneumatic SystemsDescribe how pneumatic systems use compressed air to do work, as in air drills and air brakes.
Fluids in Living ThingsDescribe how living things depend on fluid pressure, from blood circulation to breathing.

Science strand

Structures and Mechanisms

Systems in Action

How machines and other systems turn input into useful work.

Learning goals

What Is a System?Describe a system as parts working together for a purpose, with an input, a process, and an output.
Simple Machines Working TogetherIdentify the simple machines inside everyday devices and how they combine into complex machines.
Mechanical AdvantageExplain how machines multiply force at the cost of distance, and compare the mechanical advantage of simple systems.
Efficiency of SystemsDescribe why systems lose energy to friction and heat, and how design can improve efficiency.
Systems and SocietyDescribe how automated systems, from assembly lines to robots, change work and daily life.

Science strand

Earth and Space Systems

Water Systems

Earth's water — where it is, how it cycles, and how we keep it clean.

Learning goals

Water on EarthDescribe how Earth's water is distributed among oceans, ice, groundwater, and fresh surface water.
The Water CycleTrace water through the cycle of evaporation, condensation, precipitation, and runoff.
WatershedsDescribe a watershed as the land draining into a body of water, using the Great Lakes as an example.
Clean Water for CommunitiesDescribe how drinking water is treated before use and wastewater is treated after.
Protecting Our WaterIdentify threats to water systems, including pollution and climate change, and ways to protect and conserve water.
