QC Sec 4 Science & Tech study plan
QC Sec 4 Science & Tech · Give each week a clear focus.
8 weeks · About 6 hours per week
Interpreting scientific data presented in tables, graphs and diagrams
Read tables of raw measurements and restate the trend in one sentence without using the word 'increase' or 'decrease'
Label axes, units, and scale breaks on six unfamiliar graphs and record what each axis transformation hides
Convert the same dataset into a table, a line graph, and a bar chart, then judge which presentation distorts the comparison least
Identify the single most informative data point in a scatterplot and justify the choice in writing
Your checkpoint
A one-page annotated chart set: three presentations of one dataset plus a 150-word note on which is least misleading and why
Interpreting scientific data presented in tables, graphs and diagrams & Measurement, units, uncertainty and estimation
Compute slope and intercept from tabulated paired data and state the units of each
Propagate uncertainty through one addition and one multiplication worked by hand
Round reported values to the correct significant figures given instrument resolution
Distinguish precision from accuracy using three concrete measurement scenarios
Your checkpoint
A worked problem sheet of eight graph-reading and error-propagation items with full unit tracking shown at every step
Scientific reasoning and evidence evaluation
Separate observation from inference in ten short scientific passages
Evaluate whether a stated conclusion is supported, contradicted, or undetermined by the cited evidence
Identify correlation-versus-causation errors and name a plausible confounding variable for each
Rank three competing hypotheses by the strength of evidence offered for each
Your checkpoint
An evidence audit table of ten claims, each tagged supported / contradicted / undetermined with a one-line justification
Experimental design, variables and controls
Write operational definitions for independent, dependent, and at least two controlled variables in three scenarios
Design a negative control and a positive control for a described assay
Detect confounding, sampling bias, and missing blinding in four flawed study summaries
Explain why random assignment differs from random sampling in a short written answer
Your checkpoint
A full experimental design for one scenario: hypothesis, variables with operational definitions, controls, sample size rationale, and a threats-to-validity list
Technology systems and applied problem solving
Trace input, process, output, and feedback through two everyday technology systems
Identify the binding constraint in a described system and propose one design change that relieves it
Compare two candidate solutions against fixed criteria and state the trade-off accepted
Explain how a sensor's measurement error propagates into a control decision
Your checkpoint
A system diagram plus a 200-word trade-off analysis recommending one of two design options against stated criteria
Scientific reasoning and evidence evaluation & Scientific literacy and communication
Summarize a technical passage for a non-specialist reader in under 120 words without losing the caveat
Rewrite three jargon-heavy sentences into plain language while preserving numerical accuracy
Flag overstated headlines and rewrite each to match the underlying finding
Structure a short written argument as claim, evidence, and limitation
Your checkpoint
A plain-language briefing of one technical passage plus three corrected headlines, each with a one-line rationale
Measurement, units, uncertainty and estimation & Environmental and Earth science contexts
Convert between SI prefixes and check dimensional consistency in six calculations
Estimate order-of-magnitude values for four quantities and compare against a calculated answer
Read a climate, hydrological, or energy dataset and separate natural variability from a stated trend
Identify which Earth-system feedback is relevant in two described scenarios
Your checkpoint
An estimation and units log of ten items showing the estimate, the calculated value, and the ratio between them
Interpreting scientific data presented in tables, graphs and diagrams & Scientific reasoning and evidence evaluation & Experimental design, variables and controls & Technology systems and applied problem solving & Scientific literacy and communication & Measurement, units, uncertainty and estimation & Environmental and Earth science contexts
Complete two timed mixed-domain practice sets under exam conditions and log every error by domain
Re-derive the three error types that caused the most lost marks
Rewrite one weak free-response answer to include explicit evidence and a stated limitation
Build a personal checklist of recurring traps drawn from your own error log
Your checkpoint
A timed mock score report with an error log, a corrected free-response answer, and a one-page trap checklist
Milestones
Week 2: Read an unseen graph with a broken axis and correctly state the trend, the units, and one thing the axis choice obscures
Week 4: Given a flawed study summary, name the missing control, the confound, and one fix without prompting
Week 6: Explain a technical finding to a non-specialist in under 120 words while keeping the main caveat intact
Week 8: Score at least 75% on a timed mixed-domain set, with no single domain below 60%
