Key ideas
Traditional Indigenous practices reflect relationships and connections between people and their ecological environment.
Life is organized from species to populations, communities, ecosystems, and biomes.
Energy enters ecosystems from the sun and flows through food webs, decreasing at each level.
Succession is the gradual change in an ecosystem, from pioneer species to a climax community.
Knowledge about respect and responsibility for the land has been transmitted over many years, including through the oral tradition.
Watch out for
- Thinking ecological understanding began only with modern science.
- Thinking abiotic factors like temperature and water are not part of an ecosystem.
- Thinking energy is recycled through ecosystems the way matter is.

Key ideas
A pure substance has one kind of particle; a mechanical mixture has visibly different parts; a solution is evenly mixed.
Mixtures can be separated by mechanical sorting, filtration, evaporation, distillation, magnetism, and chromatography.
In a solution, the solute dissolves into the solvent.
A graphic organizer can sort matter into elements, compounds, mechanical mixtures, and solutions.
WHMIS standards guide safe handling and disposal of lab materials, including reading warning symbols.
Watch out for
- Thinking a solution is not a mixture because you cannot see the parts.
- Thinking a dissolved solute can be recovered by filtration.
- Thinking a dissolved solute has disappeared.

Key ideas
Technologies for food, clothing, and shelter — thermos, refrigerator, central heating, fleece — address human heating and cooling needs.
Heating and cooling change matter between solid, liquid, and gas states.
Conduction transfers heat through direct contact in solids; convection moves heat through currents in fluids; radiation transfers heat as waves through space.
Heat capacity, the ability of a material to store heat, influences which materials are chosen.
A heating curve for water shows temperature and states of matter as heat is added.
Watch out for
- Thinking all materials heat up and cool down at the same rate.
- Thinking temperature keeps rising during a change of state.
- Thinking convection can happen in a solid.

The three major rock types are sedimentary, igneous, and metamorphic, connected by the rock cycle.
Earth is layered into crust, upper and lower mantle, outer core, and inner core.
Saskatchewan's primary mineral resources include potash, gold, diamond, salt, uranium, copper, and graphite.
