Grade 3 Science
7 units matched to the Manitoba Curriculum.
Learning focus
- What makes natural and human-made structures strong and stable?
- What are forces and what do they do?
- What kinds of organisms are there and how do they survive?
Units
Unit 1
Science Skills & Safety
Making predictions and observations, running a fair test that changes one thing, using simple tools safely, the engineering design steps, debugging a simple program, and how science helps solve real problems.
Learning outcome: SCI.3.C.2, SCI.3.C.3, SCI.3.C.4 · measuring, doing investigations and using materials safely
Unit 2
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: SCI.3.E.4, SCI.3.E.5, SCI.3.E.6, SCI.3.E.7, SCI.3.E.8 · contact and non-contact forces, and how pushes, pulls and twists change motion
Unit 3
Speed & Motion
Practises speed as the distance an object travels in a certain time, inertia (objects keep doing what they are doing until a force acts), and how mass and force affect how quickly motion changes.
Learning outcome: SCI.3.E.9, SCI.3.E.10, SCI.3.E.11 · speed, inertia, and how mass and force affect how quickly motion changes
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: SCI.3.E.1, SCI.3.E.2 · what structures are for, and how materials are joined
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: SCI.3.E.1, SCI.3.E.3, SCI.3.D.5 · strong and stable structures, shapes in nature and building
Unit 6
Basic Needs & Life Cycles
Practises the basic needs of organisms (food, water, air, shelter) and the life cycles of plants and animals, including metamorphosis in butterflies and frogs.
Learning outcome: SCI.3.E.12, SCI.3.E.13 · the basic needs of organisms and the life cycles of plants and animals
Unit 7
Grouping Living Things
Biodiversity (the variety of life in a place) and sorting living things into groups by their features: backbones, legs, fur, feathers, fins and more.
Learning outcome: SCI.3.E.14 · classification systems that group living things by what they have in common
