Grade 3 Science
5 units matched to the Nova Scotia Curriculum.
Learning focus
- Earth and Space Science: Soil. Learners will analyse soil in the environment.
- Life Science: Plants. Learners will investigate plants in the environment.
- Physical Science: Invisible Forces. Learners will investigate invisible forces.
- Physical Science: Structures. Learners will construct a structure in response to a design challenge.
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.
Learning outcome: Life Science: Plants · plant parts and what plants need
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.
Learning outcome: Life Science: Plants · how plants grow and change
Unit 3
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.
Learning outcome: Physical Science: Invisible Forces · forces that act without touching
Unit 4
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.
Learning outcome: Physical Science: Structures · structures and their jobs
Unit 5
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.
Learning outcome: Physical Science: Structures · what makes a structure strong and stable
