Our evidence is fictional. Read Sources A–E. The numbers are invented sensor units, not results from a real room or a safety test. Use the print and text aids if helpful. Show which source supports each statement. You can write, speak, sign, use AAC, draw a high-contrast diagram, or direct a scribe; keep the same reasoning.
Week 3
Day 11 · Read the whole poster
Circle the headline and the quieter sentence in Source A. Who wrote it, to whom, and why? Compare its four-layer prediction to Source B's four-layer record. Write a two-sentence replacement headline and one unanswered question. Choose an annotated page, claim/record cards, or a spoken/signed source comparison. Try the same routine on an entirely made-up stage-light advert at home.
Day 12 · Write the conditional model
On the model table, use P(n)=160×2^-n to predict n=0 through 4. Explain 2^0 and 2^-2 with marks, factors or words. Put the recorded B values in a different column. What would the model say at an untested n=5? Mark it prediction only. Choose paper strips, raised cards, or symbolic working. At home explain 2^-3 with eight equal marks.
Day 13 · Name the difference
Calculate record − prediction for each B row. Plot paired values or arrange number tiles. What pattern can you see, and what can't you know from B? Write one claim that B can support and one question for a better test. Choose tactile dots, number tiles, or a written table. At home invent a tiny prediction/record pair and label its difference.
Day 14 · Plan a repeat someone could follow
Ask how a sensor value varies with number of layers for this setup. Specify what changes, what is read, what stays fixed, how many readings, how to handle background light and how to record results. Use the method mat. Peer-review a partner's steps, then repair an ambiguous step. Choose procedural cards, control/measure tokens with dictation, or a written protocol. Write not observed wherever your class has not made an approved real observation. No equipment is needed at home; tell someone how a fair test would work.
Day 15 · Fresh transfer check
Your teacher will provide Check A separately. Make a first independent response with your available access tools. Afterwards, reflect on how you distinguished assumption, calculation, source and limit. At home, explain why a predicted value is not a measured result.
Week 4
Day 16 · Read repeats carefully
In D compare n=0 and n=4 across the three invented rounds. What values are close? Does that fix the mismatch with the half-model? Give one within-record conclusion and one missing method detail. Choose number strips, a raised dot plot, or a written/signed comparison. At home invent three close numbers and one changed condition you would test.
Day 17 · Try another factor
Explore P(n)=160×r^n with r=.50 and .55, using the offline tool or a paper calculator table. Compare the average absolute gap from B. A smaller gap fits these invented rows better; say why it doesn't prove that factor is a property of all paper. Use a keyboard, teacher-read output with repeated-factor cards, or a paper table. At home draw two repeated-factor steps with a factor of your choice.
Day 18 · Find the actor hidden by a noun
Read C. Who or what is missing behind “the reduction”? Trace “dependable” to a source or mark it unsupported. Rewrite C for a fictional manager, then as a concise attributed table caption. You may keep an abstract noun if its meaning is clear. Choose annotation, actor/action/result/limit cards, or dictated editing. At home rewrite a made-up sentence that claims “the improvement succeeded” without evidence.
Day 19 · Make a responsible two-panel brief
Source E asks about a small supervised retest, not approval for public use. In the canvas, make one panel with a numerical comparison and another with your decision, limitation and precise next check. Choose hand-drawn panels, tactile layout with exact-word scribe, or typed panels plus a spoken/signed explanation. Ask a peer what the first glance seems to claim; revise any overstatement. At home write a no-cost because / however / next note about fictional data.
Day 20 · Fresh reproducibility check
Your teacher will provide Check B separately. Save your first independent response before discussion. Then mark one fact, one model prediction and one unknown. At home explain the difference between repeated fictional values and a reproducible real investigation.
When you finish
Read your brief as the fictional manager: can you find the model assumption, exact record, source, missing method detail and safe next step without guessing? If not, revise. You may change format without changing the evidence.
