Unit 1 · 3 skills

Student-Directed Study

Designing the Inquiry

  • Designing a scientific investigation

    I can design a testable Chemistry 30 investigation with a question, hypothesis, and procedure.

    Official code: CH30-SDS1

Carrying Out and Analysing

  • Carrying out and analysing the experiment

    I can carry out my investigation using proper protocols and analyse the data.

    Official code: CH30-SDS1

Presenting the Study

The official wording · 3 outcomes
CH30-SDS1
Create and carry out a plan to explore one or more topics of personal interest relevant to Chemistry 30 in depth.
CH30-SDS1

CH30-SDS1
explore one or more topics of personal interest relevant to Chemistry 30 in depth.

Key ideas

  1. A testable question isolates one variable and can be answered with evidence.

  2. Following a controlled protocol keeps results valid and repeatable.

  3. A portfolio documents the process, evidence, and reflection of the inquiry.

  4. A hypothesis predicts a relationship; the design controls variables to test it.

  5. Data analysis looks for patterns and relates them back to the hypothesis.

Watch out for

  • Choosing a question too broad or non-testable to investigate.
  • Changing the procedure mid-experiment without recording it.
  • Treating the portfolio as only a final report with no process record.

Key ideas

  1. The atomic model developed from Bohr to the modern quantum understanding.

  2. Intermolecular forces (London dispersion, dipole-dipole, hydrogen bonding, ion-dipole) act between particles.

  3. Carbon's four valence electrons let it form chains, branches, and rings.

  4. A material's properties must match the product's specifications.

  5. Valence electrons and the octet rule determine ion charge and bonding.

Watch out for

  • Treating the Bohr model as the complete modern model.
  • Confusing intramolecular bonds with intermolecular forces.
  • Thinking carbon forms only single bonds.

Key ideas

  1. At equilibrium forward and reverse reactions occur at equal rates in a closed system.

  2. A saturated solution is an equilibrium between dissolved and undissolved solute.

  3. Arrhenius, Bronsted-Lowry, and Lewis theories define acids and bases differently.

  4. Concentrations of reactants and products become constant, not equal.

  5. Temperature and the common ion effect shift solubility equilibria.

Watch out for

  • Thinking equilibrium means equal concentrations of reactants and products.
  • Assuming solubility always increases with temperature.
  • Equating a strong acid with a concentrated acid.

  3. Redox equations balance by the half-reaction or oxidation-number method.

  4. Corrosion is redox; prevention methods include coating and cathodic protection.

  5. Electrochemical (galvanic) cells are spontaneous; electrolytic cells require energy input.

Watch out for

  • Reversing the definitions of oxidation and reduction.
  • Thinking corrosion is a purely physical process.
  • Forgetting to balance charge as well as atoms.
