Retrieve only what has already been taught

W13A: change one variable, measure distance and keep controls fixed.
Lessons 9–10: a conclusion needs relevant evidence and reasoning.
W5: repeats reveal variation and support a pattern.
W3: friction opposes movement between surfaces.

New to this class, absent, or not sure? Everything needed is in the retrieval box above. Read it, point to it or ask a familiar adult to read it exactly.

◆ Supported

Point to the one variable changed in the surface test.
Point to centimetres as the distance unit.
Count the three result boxes for each condition.
Complete: Keep every result, even if it is ___.

▲ Standard

State the surface-test independent and dependent variables.
Name two controls from the plan.
Explain why the rover is released without a push.
Predict which surface gives the greater distance and why.

★ Stretch

Explain what to do with an unexpected but valid result.
Calculate a range and explain how it shows variation.
Name one method repair if a run leaves the lane.
State one limit of applying the result to a planetary rover.

WHAT THIS MODEL HELPS US SEE

The fixed six-result set provides a complete parity route and models how raw data become a cautious conclusion.

WHAT THIS MODEL DOES NOT SHOW

A short classroom ramp tests one rover, two surfaces and one set of conditions; it cannot represent gravity, terrain or every real rover design.

Step 1

Check the safe lane, low ramp, marked start and same rover. Commit a prediction before releasing anything.

Step 2

Release without a push, measure from the same line and record immediately. Repeat three times before changing condition.

Step 3

Keep every valid result. If the method fails, preserve the first note, repair the setup and repeat the run.

Word help keeps the scientific term visible and adds a plain-language bridge.

👩‍🏫 I Do 2 · connect the second idea

Connect the model to the second idea

Connection: the model is useful when its visible pattern is translated into a scientific explanation.

Connection 1

New investigation evidence: smooth 48, 51, 49 cm; fabric 27, 29, 28 cm. Every smooth result is greater.

Connection 2

Typical distance is about 49 cm on smooth and 28 cm on fabric. The observed intervals 48–51 cm and 27–29 cm do not overlap; the numerical ranges are 3 cm and 2 cm.

Connection 3

Conclusion: the rover travelled farther on smooth surface because lower friction opposed its motion less. State that the classroom model is simplified.

MODEL STRENGTH

The fixed six-result set provides a complete parity route and models how raw data become a cautious conclusion.

MODEL LIMIT

A short classroom ramp tests one rover, two surfaces and one set of conditions; it cannot represent gravity, terrain or every real rover design.

✏️ Independent · evidence of learning

Carry out or direct the fair rover test, record two conditions with three repeats, then give a conclusion, improvement and limitation.

👐 Physical route

Stable low ramp; same rover; smooth and fabric surface conditions; ruler or tape; six-row table; lane markers.

Same outcome: I can carry out a comparative fair test, use repeated distance results for a conclusion and improve the method.

🖥 Offline digital / director route

Run the same reasoning route with the fixed smooth and fabric results: 48, 51, 49 versus 27, 29, 28 cm.

Same evidence: Prediction, all six raw results, pattern statement, evidence-linked conclusion, one improvement and one model limitation.

🧰 Equipment / setupStable low ramp; same rover; smooth and fabric surface conditions; ruler or tape; six-row table; lane markers.

🛡 Safety / sensoryTeacher checks the ramp and clear lane. Release without pushing; keep hands, feet and faces away from the moving rover.

🖥 Offline parityRun the same reasoning route with the fixed smooth and fabric results: 48, 51, 49 versus 27, 29, 28 cm.

No-equipment/access route: Direct an adult through the physical method or use printed fixed data. Observation and decision roles are complete participation.

◆ Supported

Direct each run, match the six values to conditions and complete an oral or symbol-supported conclusion.

Scaffold

Adult handles equipment; use pre-labelled rows and the frame: On ___ it went ___ because ___.

▲ Standard

Complete three safe repeats per condition, record all results and write a conclusion plus one improvement.

Scaffold

Check the method against change, measure, keep and repeat before concluding.

★ Stretch

Compare typical values, calculate numerical ranges, explain variation and evaluate transfer to a real rover.

Scaffold

Suggest one justified method improvement without changing the original raw data.
