Ten new-case formative checks · learner promptsYear 9 Subjects · T1 W3–4 · Assessment guide

Use one area check on Day 15 (A) and one on Day 20 (B). These prompts and the teacher key are publicly accessible, so they are not secure examinations or validated measures. They are new relative to earlier lesson practice, but a learner may have seen them online. For first-encounter evidence, create a locally unseen parallel case with the same reasoning demand; do not claim security from file placement. Allow neutral read-aloud, large print, tactile cards, AAC/sign, keyboard or learner-directed transcription, and record a content hint separately. All people, data, counts, designs and scenarios below are original fiction. A paper model is not an observed real-world outcome.

Day 15 · one chosen area

Science A · new carbon-path card

An invented paper diagram says air CO₂ → pond plant carbon and pond plant carbon → air CO₂. Its two arrows are drawn the same length. A caption claims: “The pond removes exactly as much carbon as it releases every day.”

1. Name a process that could label each arrow and the Earth spheres linked. Explain why the paper arrow lengths cannot establish equal carbon amounts.
2. Rewrite the caption as a bounded statement and name one measurement needed for an actual daily balance.

HASS A · new route and referendum models

Route card: Fictional Stop R to Archive A takes 16 minutes, with step-free status unknown. Fictional alternative takes 9 + 8 minutes and is marked step-free in the imaginary timetable. No cost/service frequency is supplied.

Referendum card: Invented States A–F each have 100 votes. Their yes counts are 62, 58, 53, 51, 48, 40; their no counts fill each state to 100. Fictional territories together have 80 yes and 20 no. For a constitutional referendum, use the real rule: national yes majority and yes majorities in at least four of six states.

1. Compare travel time and one missing access/choice detail; do not advise a real traveller from the imaginary card.
2. Calculate national yes/no and number of states with yes majorities. Does this fictional tally pass both conditions? Show how you know.

HPE A · new inclusive decision

An invented table-game sign says, “Only people who speak loudly may direct the team.” No actual club uses this sign.

1. Rewrite the invitation to offer at least two meaningful contribution routes without guessing anyone's ability.
2. Give a fair method for the group to decide roles and resolve a disagreement. State what you would observe before saying the new method worked.

Technologies A · new toy codec and rule

For a toy run-length code, 4B means four B symbols. The invented message is BBBBCCCAA. A separate fictional display rule says SHOW only if format_valid and reviewed are both true; otherwise RECHECK.

1. Encode the message, count old/new character lengths and decode your result to check reversibility.
2. Give outputs when (format_valid, reviewed) is (true, false) and (true, true). Explain why replacing and with or breaks the intended rule.

Arts A · new Media Arts frames

For an invented school display, Frame 1 shows an empty paper table with a caption draft “No display happened.” Frame 2 shows a paper model being placed on the same table. These are original fictional frame descriptions, not images of real people.

1. Arrange two panels for a Year 9 audience and write one accurate caption. Explain what the first frame alone may make a viewer infer and what the second changes.
2. Describe a crop or framing change that would avoid making the caption falsely absolute. A text/tactile storyboard is as valid as drawn panels for this design check; do not claim filming or distribution.

Day 20 · one chosen area

Science B · new wave and reaction cards

Card W imagines a sound source in air, then the same source in a vacuum. A small light icon is also shown in the vacuum box. Card R prints the balanced symbolic equation 2Mg + O₂ → 2MgO for the magnesium–oxygen reaction; no substances are handled.

1. Explain which transfer (sound or light) a vacuum stops in this model and why. Give one thing the simple icon cannot measure.
2. Count magnesium and oxygen atoms on both sides of R. Explain why changing MgO to MgO₂ is not the same as changing a whole-formula coefficient.

HASS B · new source and choice cards

Source card: A document written today imitates an “1890 receipt” with the line “Three boxes went to the workshop.” A modern classroom caption says “This proves workers were overpaid.” Neither card came from an archive; the receipt is a deliberate simulation.

Choice card: An invented shared-garden sign board A costs 20 credits for 10 planned uses; B costs 27 credits for 18 planned uses. Stability and legibility are unknown.

1. Explain why the fake receipt is not genuine primary evidence. Name one provenance check and one type of real source a historian could seek; assess the caption's claim.
2. Compare credits per planned use for A and B, then give one missing non-price criterion before recommending a board.

HPE B · new shared-space rule

In a made-up tabletop game, the first person to arrive keeps all four tokens for the whole round. A second player asks to take one; the first says no. No real pupil is being described.

1. Give a response that accepts the refusal without grabbing or pressuring. Offer another way to participate or request adult facilitation.
2. Propose a fairer future rule, say how the group can agree it, and name an observation that could show whether it gives meaningful participation.

Technologies B · new design brief

An imaginary desk needs a paper pocket that displays two instruction cards. Criteria: use one A4 sheet, show both labels from a stated desk position and hold both paper cards for 30 seconds in a paper demonstration. Invented test notes: candidate X uses one sheet and labels are visible but holds only one card; candidate Y uses one sheet and holds two cards for 30 seconds but hides one label.

1. Which candidates meet every criterion? Give evidence for your decision and one specific design change.
2. Write a safe next paper test and state why the test notes cannot establish a durable real product.

Arts B · new Visual Arts choice

Invented mini-display prompt: make a non-branded image using a folded square and a spiral. Fictional feedback on an initial sketch says, “The spiral is hard to notice beside the thick square outline.” No actual audience was surveyed.

1. Make or direct two tiny compositions. Revise at least one line weight or spacing choice and identify the exact before/after change.
2. State the intended viewer effect and how you might test it with a willing viewer. Do not claim the display or feedback trial has occurred.
