Child job
Ask a fair muffling question without guessing its result.
Day
48
Guided different try
C16 fictional theatre log states same lid action and observer spot, cover absent report “tap”, cover present report “less clear to this reporter”. Force unmeasured. Possible: “One supplied reporter found covered less clear; this is not a measured reduction or a claim about every cover.”
Held offer
C-later held fully new notes and exact prompts.
Home
HomeH08: on paper, plan whether a pretend cushion might change a puppet prop report. Ask what to keep similar and what a real report would need. No wrapping devices, ear tests or sound demand. Bring back the question if desired.
Lesson minutes
30–40 optional; split moves over smaller sessions as needed. Days are resource sequence slots, not required daily Science attendance.
Next teaching
If prediction becomes result, use an unrelated paper-bridge story predicting two toy figures will fit but no trial held. Put prediction before blank trial area, then child reconstructs a fresh cover record.
Observe
Observe separation of prediction, reported outcome and missing outcome; practical versus unperformed status recorded honestly.
Ordinary model
C15 fictional reading-desk team predicts a cloth may make a tap seem softer. Uncovered tray/tap is reported “soft”; cloth-cover tray/tap has no result supplied. Possible: “The prediction is untested in these notes. We need the covered report before comparing.”

Project
ProjectX08: create an open-question test board with clearly separated Before prediction, Procedure, Results still open and Next question. A partner reviews the plan and leaves their own feedback blank until offered.
Read aloud
R08: “Could a cover change a report? That is a question. We can predict and still say ‘not tried’. A missing result needs room, not a pretend answer. Choose a gentle real try or a quiet plan. If you stop, keep the plan. Our guide is useful when it tells the truth about what happened.”
Routes
Id
A
Limit
No decibel reduction, hearing-protection certification or universal winning material.
Name
Gentle cover question
Outcome
An honest actual comparison with limits or an unperformed plan.
Steps
With adult approval name cover/no-cover as chosen change, predict based on experience and agree one gentle event each with same observer spot where possible. Record only welcome actual reports or uncertain/no report. With guidance compare to prediction and note unmeasured force/fit. Stop rather than increase volume.
Id
B
Limit
No actual muffling experiment performed.
Name
Quiet gap detective
Outcome
A faithful prediction/result/gap guide.
Steps
Read completeC15/C16. Sort prediction, supplied result and missing result cards. Make an organiser for one source, leaving its gap plainly labelled. Give a question that would help decide the stated job, not an invented outcome.
Id
C
Limit
Covering a drawing does not physically muffle sound.
Name
Design the next test
Outcome
A usable guided future plan with quiet parity.
Steps
Build a tabletop paper plan with cover/object/action/spot cards. Child chooses one change and a way to record report provenance. Helper mimes sequence; child revises any unsafe/unclear instruction. Leave real result boxes empty.
Six moves
- Hook3min: show an uncovered and cloth-covered pretend prop picture. Which is a prediction and which is a result?
- Read5min: C15 prediction and supplied records including the missing covered result.
- Teach5min: a muffling question can remain open. A cover may change more than one condition; personal descriptions are not a level-meter reading.
- Model5min: make a before/after organiser without inventing an after report.
- Try12min: optional approved cover comparison, quiet gap detective or cover-plan builder. Child picks a useful further question.
- Exit4min: check every result label against actual/source notes. Offer C-later separately.
Teacher preparation
Prepare C15–16,V08,W08. Real optional setup uses only adult-approved empty container and broad soft cloth outside container; no ear covering, face covering, electronics wrapping or hidden small loose objects. Agree gentle action/listener spot and stop. No requirement to hear or to find a winning material.
Title
Could a cover change the report?
Worksheet
W08 Muffling inquiry: empty Purpose, Question, Prediction/experience, Safe procedure, Cover choice, Similarities, Uncovered note, Covered note, Evidence kind and Comparison/question; missing results stay empty.
