- How can genetics help explain evolution?
Units
Unit 1
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.
Learning outcome: SCI.9.E.15, SCI.9.E.21 · cell division, asexual reproduction and genetic material
Unit 2
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.
Learning outcome: SCI.9.E.16, SCI.9.E.18 · sexual reproduction and variety in traits
Unit 3
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.
Learning outcome: SCI.9.E.4, SCI.9.E.5 · atoms and their internal structure
Unit 4
Electrons & Compounds
How valence electrons decide whether atoms gain, lose or share electrons, ionic and covalent compounds, and reading simple chemical formulas.
Learning outcome: SCI.9.E.2, SCI.9.E.3 · chemical and physical change, and conservation of mass
Unit 5
Electric Current
Static electricity, current, voltage and resistance, solving V = I × R, series and parallel circuits, electrical safety, and electricity generation in BC.
Learning outcome: SCI.9.E.10 · current electricity: polarity, voltage, current and resistance
Unit 6
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.
Learning outcome: SCI.9.E.7 · the arrangement of the elements on the periodic table
Unit 7
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.
Learning outcome: SCI.9.E.1 · pure substances, elements, compounds and mixtures
Unit 8
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.
Learning outcome: SCI.9.E.6 · static electricity: attraction, repulsion and charging
Unit 9
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.
Learning outcome: SCI.9.E.8, SCI.9.E.12, SCI.9.E.13, SCI.9.E.14 · alternating and direct current, generating electricity, hydroelectricity and electrical safety
Unit 10
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.
Learning outcome: SCI.9.E.19, SCI.9.E.20, SCI.9.E.23, SCI.9.E.24, SCI.9.E.25, SCI.9.E.26, SCI.9.E.27, SCI.9.E.28 · mutations, adaptation, evidence for evolution, natural and artificial selection
