These sources were written for this Year 8 inquiry. The people, club, rails, offers, trial counts, budgets and events are invented, not a real venue or collected student data. Read exactly aloud when needed; label that as listening-supported comprehension, not independent print decoding. No actual purchasing, travel, real-person survey or public installation is involved. Values describe paper models only.
Source A An editor's brief and a claim
The fictional Open Page Lab wants a small paper exhibition about how a page invites a reader. Its draft plan shows two equal drawn rails, each 96 cm wide. Each rail has a 12 cm left margin, n equal 18 cm paper panels, and a 12 cm right margin. The editor writes: “Our twin rails welcome every story and every reader. Four panels fit perfectly, so the real pop-up can open tomorrow.” No real site, mounting hardware, audience or timetable has been checked. The group may make paper sketches and prototypes. It may not treat this draft as permission to install or invite anyone.
The editor asks for a corrected visitor-facing caption, a small visual design, a test of one material assumption and a recommendation about a fictional budget. A good response keeps a useful result while making its source and limit easy to see.
Source B The two-rail paper calculation
For one drawn rail, R(n)=12+18n+12=24+18n centimetres. For two identical rails together, T(n)=2(12+18n+12)=2(24+18n)=48+36n centimetres of total paper-strip length. At n=4, one rail uses 96 cm and both use 192 cm in total. At n=5, one uses 114 cm and both use 228 cm. Adding the two rails does not make either single rail 192 cm wide. The rule omits clips, gaps, bent paper, mounting and the measurements of any real surface.
Panels per rail n |
One drawn rail R(n) |
Two rails total T(n) |
Model claim |
|---|---|---|---|
| 0 | 24 cm | 48 cm | margins only |
| 2 | 60 cm | 120 cm | each rail still has its own margins |
| 4 | 96 cm | 192 cm | each matches its 96 cm drawing |
| 5 | 114 cm | 228 cm | each exceeds the 96 cm drawing |
Source C Safe paper-support trial and constructed fallback
Investigable question: With all else held as similar as possible, does changing a paper bridge from flat to a lengthwise zigzag fold change how many identical paper tabs it holds before the centre sags 1 cm? This small classroom investigation tests a paper support, not a real display's safety.
Practical route: Put two stable closed books or equal-height supports 15 cm apart on a clear desk. Bridge the gap with one A4 sheet resting 2 cm on each support. Compare a flat sheet with a second same-stock A4 sheet folded lengthwise into a repeated zigzag. Place equal 5 cm square paper tabs at the centre, one at a time, wait three seconds, and stop when the centre first sags at least 1 cm below its starting position. Keep span, paper stock, tab size, placement and the sag rule the same. Use a ruler and repeat three times with fresh or equivalently uncreased sheets. Keep all objects below shoulder height; use paper only, no weights or sharp tools. Stop if supports slip. Teacher checks local safety and available materials. A learner may direct the test or analyse the supplied constructed data instead.
Constructed fallback only, never presented as observed class results:
| Paper bridge form | Trial 1 tabs before stop | Trial 2 | Trial 3 | Mean |
|---|---|---|---|---|
| Flat | 1 | 2 | 1 | 4/3 ≈ 1.33 |
| Zigzag fold | 4 | 4 | 5 | 13/3 ≈ 4.33 |
The constructed set suggests a difference in this model. It does not establish a safe mounting capacity or that the fold always wins. Paper stock, fold regularity, tab placement, support slip, sag judgement and short wait can affect results. If a tab drops, it moves downwards: its gravitational potential energy decreases as kinetic energy increases; sound and thermal energy may be produced on impact. This observation alone does not quantify energy. Do not intentionally drop heavy objects.
Source D A second hybrid notice about time
EVERYONE GETS A DEMO! The fictional desk has a 50-minute model session. Setup takes 5 minutes. Each complete paper demonstration takes 15 minutes. Let
dbe a non-negative whole number of complete demonstrations. The rule is5+15d≤50. Three use 50 minutes; four need 65. Question time, changeover, access arrangements and the number of people who want a turn are unknown. The editor plans to assign slots, but the notice does not say who will do it.
The headline is an invitation plus an unsupported universal promise. The time rule bounds demonstrations, not people. This source is a new fictional notice for the integrated inquiry, not a booking or permission to run an event.
Source E Two fictional supplier cards and a price change
For p equal paper panels in total across both rails, Supplier F quotes F(p)=12+2p tokens (12-token setup, 2 per panel). Supplier G quotes G(p)=4p tokens (no setup). The imaginary material budget is 30 tokens. At p=4, F costs 20 and G costs 16; at p=8, F costs 28 and G costs 32. If G's quoted per-panel amount changed from 4 to 6, as a what-if only, its four-panel total would be 24, above F's 20. Neither card describes actual money, material quality, waste, availability, labour or a contract. A lower quoted total alone does not decide which material is suitable. The budget and two-rail model put different constraints on the choice.
Source F Visual and digital audience notes
Fictional artist note: “I want a left margin that helps a reader begin, not a page packed to its edge. A line of type can feel like an invitation or like a wall.” This is one artist's intention, not measured visitor experience. The team may make two original paper caption compositions using spacing, size and emphasis, then ask a consenting reader which source and limit they can find. No cultural motif or other artist's work should be copied.
Fictional digital user story: “As a reader of the paper proposal, I want to enter a whole panel or demonstration count, see the model result and its limit in plain text, so I can challenge an overconfident headline.” The optional offline model-audit tool runs in the browser without accounts or network calls. It calculates from the fictional rules above and keeps no submitted data. Its values are demonstrations, panels and paper lengths, not actual attendance or safety approval. A paper table is an equal route; only a learner who actually inspects/changes a user-interface design generates Digital Technologies design evidence.
Source G Commissioner's closing request
The fictional editor can choose a paper-only two-rail draft, a one-rail draft, or postponement pending tests. Give the editor a short recommendation that names: a model width or time result; one test finding or limitation; the relevant fictional supplier comparison; and one design/caption change that a new reader could understand. Describe which evidence came from which source. A thoughtful recommendation can say that a real installation is premature. The editor will not receive a real message.
