Grade 3 Science: how to help at home
What your child learns in Grade 3 science in the New Brunswick Curriculum, and simple things to try at home.
The Big Ideas this year
- Grade focus: Our Local Environment.
- Scientific Literacy: Investigation. Plan investigations to solve problems relating to the local natural world: weather and climate, habitats, plants, and animals.
- Scientific Literacy: Sensemaking. Analyze data to construct explanations and conclusions based on evidence from scientific inquiry.
- Scientific Literacy: Communication. Communicate procedure, result, and conclusion of scientific inquiry using a variety of media.
- Learning & Living Sustainably: Responsible and Sustainable Application. Apply scientific knowledge and an understanding of sustainable practices responsibly with respect to the local natural world.
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
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.
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.
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.
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.
What the report card levels look like at home
- Working below
- Just getting started with this idea. Short, regular practice with lots of support helps most.
- Approaching
- Understands parts of it and is building confidence. Keep practising the tricky parts.
- Meeting
- Has it! Mixed review now and then keeps it strong.
- Excelling
- 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 New Brunswick report card guide.
Common questions
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.
The New Brunswick Curriculum Grade 3 science units include plant parts & needs, how plants grow & change, pushes, pulls & forces, structures & their jobs, strong & stable.
