Child job
Make a movement model a younger reader can understand.
Day
44
Guided different try
C08 fictional tabletop note: adult slowly bends cardboard, child sees it move, no sound or receiver was recorded. Ask what the note supports. Possible: “Seen source movement is supplied; an observed receiver effect is not supplied.”
Held offer
D-first only neutral source; no held answers in model help.
Home
HomeH04: create four paper positions for a pretend wobbly flag. Move them manually with your child; label MODEL. Ask what a drawing cannot tell us about a real sound. No device, speaker or night activity is required.
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 all motion becomes sound proof, use unrelated wind-up toy source notes: its wheels move but no bell report exists. Ask which extra source would be needed for a bell claim. Return to a different movement model.
Observe
Observe whether child avoids treating arbitrary strip/drawing movement as a demonstrated receiver result; accept general fact understanding separately from missing practical opportunity.
Ordinary model
C07 fictional toy-repair instructions show paper strip at centre, left, centre, right; caption “four selected positions, no time measurement”. Possible: “This is a movement model. It does not tell us the pitch, loudness or whether a listener heard a sound.” F2 fact card says incoming sound waves can make the eardrum vibrate; it is a reference account, not this child’s observation.

Project
ProjectX04: make an original four-frame movement flipbook with a clear model caption and separate blank real-observation page. A helper checks labels, not sound performance. Share only the model if the child wants.
Read aloud
R04: “This drawing is waiting. You choose when it moves. One frame, then another. What moved in our model? What did we really observe? A model can help us think, but it cannot listen for us. We can use a fact card and still leave our own result open. Let us tell the reader which kind of clue we used.”
Routes
Id
A
Limit
Source movement is not proof that sound energy caused a separate object to vibrate.
Name
Gentle strip observer
Outcome
One actual movement note with receiver unknown.
Steps
Adult checks a broad strip and clear space; child predicts what may move and agrees one gentle flex/release. Observe visually or direct a helper. Describe only actual movement and optional heard report. Separate own event fromF2 reference; ask how a receiver effect could be investigated safely later.
Id
B
Limit
Reading a fact can support knowledge; it does not complete conducting evidence.
Name
Quiet reference explainer
Outcome
An attributed general explanation and an open practical gap.
Steps
ReadC07 and the shortF2 fact card. Put model/fact/own blank columns on W04. Draw source and receiver labels without provider artwork. Explain which connection is general source knowledge and which actual effect remains untested here.
Id
C
Limit
Model setting is an authored illustration, not measured frequency/amplitude or listener response.
Name
Frame-by-frame director
Outcome
Two small movement storyboards with labels.
Steps
Set model choices deliberately, Step one frame at a time, pause to sketch each position and reset model alone. Paper route rotates through the same four position cards. Compare two chosen model settings and tell a reader that the frame is a model, not a recorded sound.
Six moves
- Hook3min: move one paper strip then stop. Is this a drawing, a moving strip or a sound record?
- Teach5min: separate source movement, receiver movement and evidence type. GeneralF2 fact is an external reference; our own strip observation is a different event.
- Read5min: read fullC07 model notes and boundedF2 fact. Do not draw a measured wave graph or show an ear diagram as if collected locally.
- Model5min: step a still drawing manually; label what changed and what the model cannot show.
- Try12min: choose strip observation, quiet receiver explainer or manual model storyboard. Reader may decline animation and use all four paper frames.
- Exit4min: child shows one labelled distinction and one unanswered receiver question. D-first source offered separately.
Teacher preparation
Prepare C07–08,V04,W04 and F2 facts card. SoundDesk model has no audio and no automatic motion. Optional adult-approved broad paper strip can be gently flexed once in open space; no rigid ruler/flinging material. The observed strip motion demonstrates that strip motion only. Use source-labelled general receiver fact, not a pretended tested speaker/ear experiment.
Title
See a movement, name its source
Worksheet
W04 Three evidence lanes: empty Actual event, Supplied model, Referenced general fact, plus source/action/receiver/not tested/question. Four blank storyboard frames carry no preset motion arrows.
