PUPIL WORKSHEET
Build and test a muscle model
Autumn 1 · Week 4 · Lesson B
Name: ____________________________ Date: __________________
Construct or direct a safe card-arm model, demonstrate both muscle roles and evaluate a model limitation.
Use this sheet with the lesson. You may point, sign, speak, draw, write, dictate or direct an adult. Keep your first idea so you can show what changed.
1. Build or direct the safe model
Adult prepares card, holes, fixed split pin and opposite-side pull tabs. Keep model on table. Never use stretched elastic.
My role: build / direct / label / explain.
The adult checked ___.
The join can turn: yes / adult adjustment needed.
PUPIL TASK / Autumn 1 · Week 4 · Lesson B
2. Record the two actions
Write, draw, point or dictate as agreed with your teacher.
Use each gentle pull and place the muscle labels.
| Action | Biceps label | Triceps label | What I observed |
| Bend at elbow | |||
| Actively straighten |
PUPIL TASK / Autumn 1 · Week 4 · Lesson B
3. Check, improve and explain
Write, draw, point or dictate as agreed with your teacher.
Check a label or model join. Ask an adult to adjust the join if needed.
What I checked: ___.
My change: ___.
My science reason: ___.
This model differs from a real arm because ___.
PUPIL TASK / Autumn 1 · Week 4 · Lesson B
4. Feedback and exit
Write, draw, point or dictate as agreed with your teacher.
Tell the adult an access need or pass. Choose one question and explain or point.
Supported: which muscle contracts for a bend?
Standard: explain both roles for active straighten.
Stretch: why do we need pulls on opposite sides?
Choose a response route
Agree one route with your teacher; you do not need every route.
Supported
Use adult-prepared model and point to or direct labels for each action.
Standard
Build or direct both moves and explain the two muscle roles.
Stretch
Compare model with living muscle and justify a precise improvement.
Next: the current Week 5 lesson.

BUILD Science Autumn1 W4 Cards and Labels
PRINTABLE CARDS / WEEK 4
Muscle names and roles
Cut along the table lines, or point to a card without cutting.
Adult makes a safe table-based card model. Move role labels for each action. No strings around any body part; use loose strings, never stretched elastic.
| Card | Card |
| BICEPS | TRICEPS |
| CONTRACTS | RELAXES |
| CONTRACTS | RELAXES |
| BEND AT ELBOW | ACTIVELY STRAIGHTEN AT ELBOW |
Print only the sets you need. Adult preparation is an alternative to pupil cutting. These are original teaching labels and simplified models.
PRINTABLE CARDS / WEEK 4
Model-component labels
Cut along the table lines, or point to a card without cutting.
Card represents bone; the turning join represents an elbow; a loose manually pulled string represents the effect of muscle pull. String does not contract itself.
| Card | Card |
| CARD = BONE MODEL | TURNING JOIN = ELBOW MODEL |
| LOOSE STRING = MUSCLE-PULL MODEL |
Print only the sets you need. Adult preparation is an alternative to pupil cutting. These are original teaching labels and simplified models.
