Grade 3 Science: how to help at home
What your child learns in Grade 3 science in the Manitoba Curriculum, and simple things to try at home.
The Big Ideas this year
- 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?
Easy ways to practise science at home
- Try a kitchen experiment, such as what dissolves in water and what floats or sinks.
- Keep a simple weather or moon log for a month.
- Ask “What do you think will happen?” and then test it.
- Visit a park, beach or creek and look for living things and their habitats.
What each unit covers
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.
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.
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.
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.
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.
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.
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.
What the report card levels look like at home
- Level 1
- Just getting started with this idea. Short, regular practice with lots of support helps most.
- Level 2
- Understands parts of it and is building confidence. Keep practising the tricky parts.
- Level 3
- Has it! Mixed review now and then keeps it strong.
- Level 4
- Applies it confidently, even in new or harder situations. Try challenge mode and real-life problems.
Your child’s teacher decides the level on the report card. Read the Manitoba report card guide.
Common questions
How can I help my Grade 3 child with science?
Try a kitchen experiment, such as what dissolves in water and what floats or sinks. Keep a simple weather or moon log for a month. Keep sessions short, about 10 to 15 minutes, and stop on a success.
What does my child learn in Grade 3 science in Manitoba?
The Manitoba Curriculum Grade 3 science units include science skills & safety, pushes, pulls & forces, speed & motion, structures & their jobs, strong & stable, basic needs & life cycles.
