Topic 8.3 representation anchorUse the picture together with words and equations—not as decoration.
A physical system is described by this Topic 8.3 situation: Block rests on water.
- (a) State the physical model and identify the system, reference point/axis, or sign convention needed before calculation.
- (b) Starting from F_B = ρ_fluid g V_displaced, derive or calculate the requested quantity symbolically before substituting numerical values when possible.
- (c) State the SI unit and explain whether the sign or magnitude of the result is physically reasonable.
- (d) Identify one assumption or condition that must be true for the relationship you used.
Reasoning and scoring guide
- Part (a): identifies the correct system/model and necessary convention.
- Part (b): uses F_B = ρ_fluid g V_displaced consistently and shows an algebraic pathway rather than an unsupported answer.
- Part (c): gives the correct SI unit and interprets sign/magnitude in the physical context.
- Part (d): states a valid condition from the Topic 8.3 scope. Expected physical conclusion: F_B=mg; it displaces fluid whose weight equals block weight.
Physics modelCorrect system, principle, assumptions and relationship.
RepresentationDiagram/graph/equation is labeled and actually supports the claim.
Evidence & unitsQuantities, units, trends and experimental evidence are physically consistent.
CommunicationReasoning explicitly connects evidence to the conclusion.
Consider this Topic 8.3 situation: Object hangs underwater from a scale.
- (a) Draw or describe the most useful representation for the situation: a graph, vector/force/torque diagram, energy or momentum bar chart, motion representation, or fluid schematic as appropriate.
- (b) Label the quantities and directions that carry physical meaning in the representation.
- (c) Translate the representation into one or more equations or proportional relationships.
- (d) Use the representation to predict how the result changes if one physically relevant parameter is increased while the others are held fixed.
Reasoning and scoring guide
- Part (a): chooses a representation that directly exposes the Topic 8.3 model rather than a decorative sketch.
- Part (b): labels relevant signs, directions, axes, energy stores, momentum vectors, or fluid quantities.
- Part (c): connects the representation to a valid relationship such as ΣF_y = ma_y.
- Part (d): makes a correct parameter-change prediction and justifies it from the representation/equation. Expected core reasoning: T + F_B = mg at rest, so T=mg−F_B.

Design a feasible classroom investigation of a relationship from Topic 8.3, using F_B = ρ_fluid g V_displaced as the starting model.
- (a) State a testable question and identify the independent and dependent variables.
- (b) Describe equipment, what is measured directly, and at least two important control variables.
- (c) Describe repeated trials and one method for reducing or estimating measurement uncertainty.
- (d) Specify the graph to plot, including transformed/linearized axes if useful, and state what feature of the graph would support the model.
- (e) Name one realistic source of systematic error and state how it would bias the result.
Reasoning and scoring guide
- Part (a): varies one physically relevant quantity and measures a response predicted by the model.
- Part (b): gives measurable quantities and controls parameters that otherwise change the predicted relationship.
- Part (c): uses repeated measurements and an explicit uncertainty/reliability method.
- Part (d): proposes a graph whose slope/intercept/shape can be compared with F_B = ρ_fluid g V_displaced.
- Part (e): identifies a concrete systematic effect and predicts its direction of bias rather than merely saying “human error.”

Use this Topic 8.3 situation: Cargo added to boat.
- (a) Make a qualitative prediction before calculating and identify the physical principle behind it.
- (b) Use a Topic 8.3 relationship to support the prediction quantitatively or proportionally.
- (c) A student claims, “Floating means buoyant force is greater than weight.” Evaluate the claim and correct it using the same physical model.
- (d) State a limiting case or boundary condition that provides an independent check on your conclusion.
Reasoning and scoring guide
- Part (a): states a defensible prediction and names the governing principle.
- Part (b): connects the prediction to a correct equation/proportionality with defined quantities.
- Part (c): rejects the misconception for the right reason: At rest, they are equal.
- Part (d): uses a physically meaningful limit or scope condition to check consistency. Expected situation conclusion: Greater total weight requires greater buoyant force, so boat displaces more water and sits lower.
