Québec Sec 4 Applied Science and Technology (057-410) study plan

Distinguish among mass, volume, density, and weight, and compute density from measured mass and volume for at least ten sample substances.

Classify given samples as pure substances (elements, compounds) or mixtures (homogeneous, heterogeneous) and justify each classification with observable evidence.

Describe the particle model of matter and use it to explain the differences among solids, liquids, and gases, including compression and diffusion.

Interpret a table of characteristic physical properties (melting point, boiling point, density, solubility, conductivity) to identify an unknown substance.

Explain the difference between a physical change and a chemical change, and classify at least 15 everyday transformations with evidence for each choice.

Balance at least 10 chemical equations and identify the reactants, products, and type of reaction (synthesis, decomposition, combustion, oxidation, acid-base, precipitation).

Describe the signs of a chemical reaction (gas, precipitate, colour change, heat, light) and apply them to a practical scenario.

Use the law of conservation of mass to solve simple mass problems in closed systems.

Identify the solute, solvent, and concentration in given solutions, and calculate concentration in g/L and in percent by mass.

Describe the effect of temperature and surface area on dissolving rate and design a fair-test procedure to compare two dissolving conditions.

Distinguish acids from bases using the pH scale and name two common indicators and the colour changes they produce.

Explain exothermic versus endothermic transformations and classify at least six examples, including phase changes and combustion.

Trace an energy transformation chain in a household device and label the useful output and the wasted output.

Build a classification key that sorts at least 12 organisms into kingdom-level groups using observable criteria.

Compare the main characteristics of the five kingdoms and give two representative organisms for each.

Explain how a specific adaptation (structural, behavioural, or physiological) improves survival in a named habitat.

Describe the levels of organization from cell to organism to population to ecosystem and give one example at each level.

Distinguish producers, consumers, and decomposers and construct a food web with at least six organisms from a named Québec ecosystem.

Describe the function of the main systems (digestive, respiratory, circulatory, excretory, nervous) and how they cooperate to maintain the internal environment.

Explain homeostasis using at least two concrete feedback examples such as body-temperature regulation or blood-glucose control.

Compare sexual and asexual reproduction and give two advantages and two disadvantages of each.

Solve monohybrid genetics problems using Punnett squares, distinguishing genotype from phenotype and dominant from recessive traits.

Interpret a pedigree or family trait chart to infer whether a trait is dominant or recessive.

Apply the engineering design cycle to a stated problem: define constraints and criteria, generate two solutions, and select one with justification.

Produce a technical drawing that includes a front view, a top view, and a side view, with correct scale and dimension lines.

Match materials (wood, metal, plastic, composite) to a design need and justify the choice with two properties such as strength, cost, or durability.

Identify the function of standard drawing conventions: line types, hatching, section views, and dimensioning symbols.

Analyse at least three mechanisms (lever, pulley, gear train, inclined plane) by identifying the input, output, and type of motion, and compute mechanical advantage where applicable.

Draw and interpret a simple series and a simple parallel circuit, and predict the effect of adding or removing a component.

Apply Ohm's law to solve at least five numerical problems for voltage, current, and resistance.

Explain the rock cycle and classify six rock samples as igneous, sedimentary, or metamorphic with a reason for each.

Describe the water cycle and one human impact on a watershed, and explain the cause of seasons and Moon phases using a labelled diagram.

Design a controlled experiment with a clear hypothesis, one independent variable, controlled variables, and a data table, then write a conclusion that accepts or rejects the hypothesis.

Graph experimental data correctly (axis labels, units, scale, title) and describe the relationship shown.

Evaluate a scientific claim or media report by identifying the evidence, the method, and one limitation.

Complete two full-length timed practice sets under exam conditions and review every error against its domain.

Consolidate weak areas by reworking the five most-missed question types from earlier weeks.
