Strands and outcomes
- Life Science: Habitats and Communities (HC4.1–HC4.3): Investigate the interdependence of plants and animals, including humans, within habitats and communities. Analyze the structures and behaviours of plants and animals that enable them to exist in various habitats. Assess the effects of natural and human activities on habitats and communities, and propose actions to maintain or…
- Physical Science: Light (LI4.1–LI4.3): Investigate the characteristics and physical properties of natural and artificial sources of light in the… Analyze how light interacts with different objects and materials to create phenomena such as shadows, reflection… Assess personal, societal, and environmental impacts of light-related technological innovations including optical…
- Physical Science: Sound (SO4.1–SO4.3): Explore natural and artificial sources of sound in the environment and how those sounds are detected by humans and… Draw conclusions about the characteristics and physical properties of sound, including pitch and loudness, based… Assess personal, societal, and environmental impacts of sound-related technologies.
- Earth and Space Science: Rocks, Minerals, and Erosion (RM4.1–RM4.3): Investigate physical properties of rocks and minerals, including those found in the local environment. Assess how human uses of rocks and minerals impact self, society, and the environment. Analyze how weathering, erosion, and fossils provide evidence to support human understanding of the formation of…
Units
Unit 1
Habitats & Communities
Habitats as places that meet the needs of living things, communities of interacting species, why habitats have limits, how species depend on each other, and how human actions can help or harm.
Outcome: HC4.1, HC4.3 · habitats and communities, and how people affect them
Unit 2
Food Chains & Webs
Producers, consumers and decomposers, herbivores, carnivores and omnivores, how energy moves along a food chain, and why a food web is a more complete picture.
Outcome: HC4.1 · how plants and animals depend on each other in food chains and webs
Unit 3
Light
Natural and artificial light, things that make light and things that reflect it, shadows, transparent, translucent and opaque materials, mirrors, refraction, and how light technology affects people and wildlife.
Outcome: LI4.1–LI4.3 · sources of light, how light interacts with materials, and light technologies
Unit 4
Sound
Vibrations and sound waves, pitch and volume, how sound travels through different materials but not through empty space, echoes and absorbing sound, how we hear, and how noise and sound devices affect people and animals.
Outcome: SO4.1–SO4.3 · sources and properties of sound, and sound technologies
Unit 5
Rocks, Minerals & Mining
Mineral properties (hardness, lustre, streak), igneous, sedimentary and metamorphic rock, the Canadian Shield, and how Saskatchewan's potash, uranium and gold mining helps and affects people and the land.
Outcome: RM4.1, RM4.2 · physical properties of rocks and minerals, and how human uses such as mining affect people, society and the environment
Unit 6
Erosion & Fossils
Weathering and erosion by water, wind, ice and glaciers, deposition, how fossils form, the T. rex Scotty from Eastend, and how fossils are evidence of Earth's long history.
Outcome: RM4.3 · how weathering, erosion and fossils are evidence of how landforms on Earth formed
