Unit 1 · 2 skills
Introduction to Chemistry
Laboratory Safety
Safe laboratory practices
I can follow safe lab practices and explain why each one matters.
Skill 1.1
How Chemistry Affects Us
Chemistry and society
I can explain how chemistry affects society and everyday life.
Skill 1.2
The official wording · 2 outcomes
- 1.1
- Recognize safe practices and explain the reason for each practice.
- 1.2
- Identify and explain how chemistry affects us.
Key ideas
Safety equipment: fire blanket, extinguisher, eye wash station, and how to use them.
Advances in chemistry create new products that change society.
Handling chemicals: treat all as hazardous, dispose properly, no pipetting by mouth.
Science and technology influence each other; some problems science cannot solve.
Watch out for
- Assuming a chemical is safe because it looks like water.
- Thinking science and technology are the same thing.
- Thinking safety rules are optional formalities.

Unit 2 · 2 skills
Laboratory Activities
Concrete Laboratory Experience
Concrete experience of chemical events
I can connect a hands-on chemical observation to the concept behind it.
Skill 2.1
Laboratory Equipment Proficiency
Manipulating laboratory equipment
I can use laboratory equipment correctly and accurately.
Skill 2.2
The official wording · 2 outcomes
- 2.1
- Acquire concrete experiences of chemical events which form the basis for abstract understandings.
- 2.2
- Gain proficiency in manipulating laboratory equipment.
Key ideas
Direct observation of chemical events grounds abstract concepts.
Measuring devices (graduated cylinder, balance, burette) each have a proper technique.
Careful observation is the raw material of chemical understanding.
Reading the meniscus and taring a balance give accurate measurements.
Watch out for
- Treating a lab as a recipe to follow without observing.
- Reading a graduated cylinder from the top of the liquid, not the meniscus.
- Ignoring qualitative observations in favour of only numbers.

Unit 3 · 1 skill
Independent Research
Investigating Chemistry Problems
Investigating problems in chemistry
I can frame and investigate a chemistry problem independently.
Skill 3.1
The official wording · 1 outcomes
- 3.1
- Investigate problems in chemistry and in the application of chemistry.
Key ideas
An investigable problem can be narrowed to a researchable or testable question.
Independent inquiry follows a plan: question, method, evidence, conclusion.
Watch out for
- Picking a question too broad to investigate in the time available.
- Confusing looking something up with investigating it.

Unit 4 · 4 skills
Atoms and Elements
Ideas About the Structure of Matter
Development of ideas about matter
I can trace how ideas about the structure of matter developed.
Skill 4.1
Components of the Atom
Components of the atom and isotopes
I can describe atomic structure, draw Lewis diagrams, and find average atomic mass.
Skill 4.2
Describing and Classifying Elements
Properties and classification of elements
I can classify and identify elements by their characteristic properties.
Skill 4.3
Organization and trends of the periodic table
I can explain how the periodic table is organized and read its trends.
Skill 4.4
The official wording · 4 outcomes
- 4.1
- Discuss the development of ideas about the structure of matter.
- 4.2
- Identify the relationships among the components of the atom.
- 4.3
- Examine how elements are described and classified.
- 4.4
- how elements are described and classified.
Key ideas
The atomic model evolved from Dalton's solid spheres to Bohr's shells.
Protons and neutrons occupy the nucleus; electrons occupy shells.
Elements have characteristic physical and chemical properties.
Theory is refined to explain new experimental observations.
Isotopes differ in neutron number; average atomic mass weights isotope abundances.
Watch out for
- Thinking the modern atomic model appeared all at once.
- Confusing mass number with average atomic mass.
- Assuming all metals share every property.

Unit 5 · 4 skills
Molecules and Compounds
Formulas and Names of Compounds
Writing formulas and names fluently
I can write chemical formulas and names for compounds fluently.
Skill 5.1
Bonding Between Atoms
Ionic and covalent bonding
I can contrast ionic and covalent bonding and predict molecular shape with VSEPR.
Skill 5.2
Forces in Solids and Liquids
Bonding in solids and liquids
I can relate the forces between particles to a substance's physical properties.
Skill 5.3
Factors Influencing Solubility
Factors influencing solubility
I can explain what factors influence how much of a solute dissolves.
Skill 5.4
The official wording · 4 outcomes
- 5.1
- Use the formulas and names of compounds fluently.
- 5.2
- Discuss the mechanics of bonding between atoms in a molecule.
- 5.3
- Examine the bonding between molecules or atoms in solid and liquid phases.
- 5.4
- Investigate the factors which influence solubility.
Key ideas
Ionic formulas balance charges of ions, including polyatomic ions.
Ionic bonds transfer electrons; covalent bonds share electron pairs.
Solid types: ionic, metallic, covalent molecular, covalent network, and van der Waals.
Water is an excellent solvent for many ionic and polar substances.
Oxidation-state notation names polyvalent metals, e.g. Fe(III); alkanes follow CnH2n+2.
Watch out for
- Forgetting to balance charges when writing an ionic formula.
- Thinking all bonds are either purely ionic or purely covalent.
- Confusing intramolecular bonds with intermolecular forces.

Unit 6 · 2 skills
Chemical Reactions
The Importance of Chemical Reactions
Recognizing and valuing chemical reactions
I can recognize a chemical reaction and describe its importance.
Skill 6.1
Communicating Reactions with Equations
Writing and balancing chemical equations
I can write and balance chemical equations, including net ionic equations.
Skill 6.2
The official wording · 2 outcomes
- 6.1
- Appreciate the importance of chemical reactions.
- 6.2
- Acquire ability to communicate chemical information through equations for reactions.
Key ideas
Evidence of reaction: colour change, gas, precipitate, energy change.
Equations must balance for both atoms and charge (conservation of mass).
Reactions sustain organisms, harm them, and affect the environment.
Net ionic equations show only the species that change; energy terms show heat flow.
Watch out for
- Confusing a physical change with a chemical reaction.
- Changing subscripts instead of coefficients when balancing.
- Assuming all reactions are harmful or all beneficial.

Percentage composition is each element's mass fraction of the compound.
Coefficients in a balanced equation give the mole ratio of reactants to products.
Molar mass links the number of moles to the mass of a substance.
Empirical formula comes from mole ratios; concentration is moles per litre.
Watch out for
- Confusing the number of moles with the number of particles.
- Confusing empirical formula with molecular formula.
- Using mass ratios instead of mole ratios.
