TASC Chemistry Level 4 study plan

TASC Chemistry Level 4 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Knowledge and Understanding of Chemistry & Scientific Inquiry and Practical Skills

  • Define and apply SI units, significant figures, and dimensional analysis to convert among units in ten mixed-measurement problems.

  • Describe atomic structure for the first twenty elements, including subatomic particles, isotopes, and electron configurations.

  • Predict periodic trends in atomic radius, ionization energy, and electronegativity, and justify each prediction in one written sentence.

  • Identify hazards and apply core laboratory safety rules to three described procedures.

Your checkpoint

A 25-item self-written quiz on atomic structure, periodicity, and measurement, scored at 80% or better, accompanied by an error log that names the misconception behind every missed item.

Week 2

Knowledge and Understanding of Chemistry & Scientific Inquiry and Practical Skills

  • Balance fifteen chemical equations, including combustion, precipitation, and acid-base reactions.

  • Compute moles, molar mass, limiting reagent, and percent yield across five multistep stoichiometry problems.

  • Design a controlled experiment that specifies a testable hypothesis plus independent, dependent, and controlled variables.

  • Distinguish accuracy from precision and classify sources of random and systematic error in a supplied dataset.

Your checkpoint

A two-page experimental design sheet for one reaction, containing hypothesis, variables table, numbered procedure, safety notes, and the calculations you expect to perform.

Week 3

Knowledge and Understanding of Chemistry & Scientific Inquiry and Practical Skills

  • Construct and interpret energy diagrams for endothermic and exothermic reactions, and calculate enthalpy change from supplied data.

  • Explain how concentration, temperature, surface area, and catalysts alter reaction rate using collision theory.

  • Apply Le Chatelier's principle to predict and justify the direction of shift in five equilibrium systems.

  • Calculate molarity and pH for strong acid and strong base solutions and describe the neutralization reaction.

  • Organize raw measurements into a labeled data table and select the graph type appropriate to the relationship.

Your checkpoint

A data-and-graph set built from ten simulated titration readings, with correctly labeled axes and units, a trend statement, a slope calculation, and a stated uncertainty.

Week 4

Scientific Inquiry and Practical Skills & Communication of Chemical Information

  • Compose a structured laboratory report using the aim, method, results, discussion, and conclusion conventions.

  • Convert between names and formulas for ionic and covalent compounds and write balanced ionic equations.

  • Critique a supplied data presentation for misleading axes, missing units, and conclusions unsupported by the numbers.

  • Apply rounding and uncertainty rules when reporting final calculated answers.

Your checkpoint

A complete 500-word laboratory report on a simulated rate-of-reaction experiment, including a data table, a captioned figure, a worked calculation, and an error discussion that passes a ten-point self-checklist.

Week 5

Communication of Chemical Information

  • Explain one chemical process to a non-specialist in 150 words or fewer using a single analogy and one quantitative statement.

  • Translate a process among word equation, formula equation, and particle-level diagram representations.

  • Construct an evidence-based argument that states a claim, cites two data points, and addresses one counterpoint.

  • Evaluate the reliability of a chemistry information source against author credentials, publication date, method transparency, and peer review.

Your checkpoint

A one-page public-facing explainer with a labeled diagram on acid deposition or electrolysis, checked against a jargon list so that no undefined technical term remains.

Week 6

Application of Chemistry to Society and the Environment & Knowledge and Understanding of Chemistry

  • Trace the environmental footprint of one industrial process from feedstock through product to waste stream.

  • Compare fossil and renewable energy sources on energy density, emissions, and renewability using cited figures.

  • Apply two green-chemistry principles to redesign a described synthesis and state the improvement achieved.

  • Calculate an environmental quantity such as ppm concentration or carbon dioxide mass released per mole of fuel combusted.

Your checkpoint

A life-cycle comparison table for two fuels or materials with at least six criteria, cited sources for every number, and a 150-word recommendation.

Week 7

Application of Chemistry to Society and the Environment & Communication of Chemical Information

  • Evaluate a consumer health or environmental claim by testing it against established chemical evidence.

  • Discuss the risks and benefits of a chemical product using dose, exposure, and hazard terminology correctly.

  • Outline how chemical evidence informs a policy decision in water treatment, plastics recycling, or drug regulation.

  • Present quantitative data in a short written brief that supports a specific recommendation.

Your checkpoint

A 300-word evidence brief arguing for or against one regulation, containing three cited data points, one acknowledged limitation of the evidence, and a clear recommendation.

Week 8

Knowledge and Understanding of Chemistry & Scientific Inquiry and Practical Skills & Communication of Chemical Information & Application of Chemistry to Society and the Environment

  • Complete a full-length timed mock examination under exam conditions without notes.

  • Diagnose the three weakest topics from the mock and reteach each on a self-made summary sheet.

  • Recall key equations, constants, and definitions from memory in a blank-page retrieval exercise.

  • Structure short answers as claim, evidence, explanation within a strict per-question time limit.

Your checkpoint

A timed 60-item mock examination scored at 80% or better, supported by a corrected error log and a one-page formula and definition sheet written from memory.

Milestones

Week 2: Balance 12 of 15 equations correctly and solve four of five stoichiometry problems unaided; the experimental design sheet lists all three variable types and a falsifiable hypothesis.

Week 4: Score 75% or better on a 40-item timed mixed quiz covering Domains 1 and 2, and pass the ten-point checklist on the laboratory report.

Week 6: Complete the life-cycle table with six criteria and at least four cited sources, and correctly calculate both environmental quantities without reference notes.

Week 8: Score 80% or better on the timed 60-item mock spanning all four domains, with no domain falling below 70%, and submit the finalized formula sheet and error log.
