Newton's First & Second Laws
State and apply Newton's First Law (an object stays at rest or constant velocity unless acted on by a resultant force) and Second Law (force = mass × acceleration), including the relationship between mass, force, and acceleration

Teaching Table
Set out your lesson
Practise the bounded task in Newton's First & Second Laws; see exact limits before inferring broader coverage.
Multiply/divide, name mass and force, distinguish velocity from acceleration.
Exact directed source edges retained; earlier authorship is not learner attainment.
These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate
Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.
Use the supplied screen cards; copying the exact task to paper is optional, not required.
Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
Ideal translational model; no actual cart experiment, crashes, or safety-device testing.
Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.
Family records and proof options

Save photos, notes, and attendance. Export a proof packet for compliance or portfolio reviews.

Check understanding
- States Newton's First Law and gives a real example (e.g. why a moving spacecraft doesn't need engines in space)
- Uses F = ma to calculate force, mass, or acceleration given the other two quantities
- Explains why a heavier object requires more force to achieve the same acceleration
- Explains why seatbelts are needed in cars using Newton's First Law
“If your child was asked why you need a seatbelt in a car but not when sitting still, could they explain what Newton's First Law says about moving objects — and then calculate how much force a 60 kg person experiences in a sudden stop?”
