Grade 9 Science: how to help at home
What your child learns in Grade 9 science in the Manitoba Curriculum, and simple things to try at home.
The Big Ideas this year
- What is matter made of?
- How is electrical energy created and distributed?
- How can genetics help explain evolution?
Easy ways to practise science at home
- Turn everyday questions into investigations: “Which paper towel holds the most water?”
- Read a science news story together and ask what evidence it gives.
- Look up how a household machine works, such as a bike gear, a lamp or a fridge.
- Have your child draw and label a diagram of something they just learned.
What each unit covers
Cells from Cells
How cells copy their DNA and divide by mitosis, the stages in order, why cells divide for growth and healing, and what can go wrong when cell growth isn't controlled.
Reproduction
How organisms reproduce with one parent or two, why sexual reproduction creates variety, the parts of a flower, and the strengths and weaknesses of each approach.
Atoms & Electrons
Protons, neutrons and electrons, drawing electron shells for the first 20 elements, valence electrons, periodic table groups and periods, and ions and isotopes.
Electrons & Compounds
How valence electrons decide whether atoms gain, lose or share electrons, ionic and covalent compounds, and reading simple chemical formulas.
Electric Current
Static electricity, current, voltage and resistance, solving V = I × R, series and parallel circuits, electrical safety, and electricity generation in BC.
The Periodic Table
Groups and periods, metals, non-metals and metalloids, alkali metals, halogens and noble gases, and how valence electrons and shells explain the patterns.
Elements & Compounds
Elements, compounds and mixtures, reading chemical formulas, physical and chemical properties and changes, density, and common household chemicals, including why some should never be mixed.
Static Electricity
Positive and negative charges and the particles behind them, charging by friction, contact and induction, conductors and insulators, and electrical safety in a thunderstorm.
Making Electricity
Practises how electricity is generated and carried, including Manitoba's hydroelectric stations, the advantages and drawbacks of different sources, AC and DC, and electrical safety.
Evolution & Selection
Practises variation, adaptation, natural and artificial selection, mutations, the evidence for evolution from fossils and rock layers, and how new species can form.
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 9 child with science?
Turn everyday questions into investigations: “Which paper towel holds the most water?” Read a science news story together and ask what evidence it gives. Keep sessions short, about 10 to 15 minutes, and stop on a success.
What does my child learn in Grade 9 science in Manitoba?
The Manitoba Curriculum Grade 9 science units include cells from cells, reproduction, atoms & electrons, electrons & compounds, electric current, the periodic table.
