7 units matched to the Saskatchewan Curriculum.
Strands and outcomes
- Life Science: Plant Growth and Changes (PL3.1–PL3.2): Investigate the growth and development of plants, including the conditions necessary for germination. Analyze the interdependence among plants, individuals, society, and the environment.
- Physical Science: Structures and Materials (SM3.1–SM3.2): Investigate properties of materials and methods of joinery used in structures. Assess the function and characteristics of strong, stable, and balanced natural and human-built structures.
- Physical Science: Magnetism and Static Electricity (ME3.1–ME3.2): Investigate the characteristics of contact (e.g., push, pull, and friction) and non-contact (e.g., magnetic and… Assess effects of practical applications of magnetic and static electric forces on individuals and society.
- Earth and Space Science: Exploring Soils (ES3.1–ES3.2): Investigate the characteristics, including soil composition and ability to absorb water, of different types of… Analyze the interdependence between soil and living things, including the importance of soil for individuals…
Units
Unit 1
Plant Parts & Needs
Roots, stems, leaves, flowers (with the stamen and pistil), fruit, seeds and cones, plus what plants need to live: air, water, light, heat, nutrients and space.
Outcome: PL3.1 · plant parts and what plants need to grow
Unit 2
How Plants Grow & Change
From seed to flower and back to seed, how seeds travel, how plants react to light and seasons, and how they use sunlight, water and carbon dioxide to make food and release oxygen.
Outcome: PL3.1 · growth, life cycles and germination of plants
Unit 3
Structures & Their Jobs
What makes something a structure, how its shape fits its job (a bowl-shaped nest, a sloped roof), structures built by animals and by people, and how they change the environment.
Outcome: SM3.2 · natural and built structures and what they are for
Unit 4
Strong & Stable
Strength as holding a load and stability as staying balanced, how shape, a wide base and materials help, and how struts (pushed) and ties (pulled) work in a frame.
Outcome: SM3.1, SM3.2 · materials, joins and what makes a structure strong and stable
Unit 5
Pushes, Pulls & Forces
Forces as pushes and pulls, contact and non-contact forces (gravity, magnetism, static electricity), friction, how bigger forces change motion more, and helmets and seat belts as safety devices.
Outcome: ME3.1 · contact and non-contact forces
Unit 6
Types of Soil
What soil is made of (rock bits, humus, air, water), how sand, silt, clay and loam look, feel and drain, how to sort and test samples fairly, and why dark prairie topsoil suits crops.
Outcome: ES3.1 · the makeup of soils and how different types, such as sand, silt, clay and loam, absorb water
Unit 7
Soil and Living Things
How plants, worms and other animals depend on soil, how soil depends on them, farming and compost on the prairies, and ways to protect soil from wind and water.
Outcome: ES3.2 · how soil and living things depend on each other, and why soil matters to people and the environment
