Finish, Test & Record

The final test checks whether the solution functions as intended — and gives evidence about the quality of the build.

Today students will…

01

Finish

the solution and correct obvious construction weaknesses.

02

Test

whether the solution functions as intended under the standard condition.

03

Finalize

the list of changes made during creation.

Criterion D is only formative here.Formal assessment remains B + C
Before Testing
Final quality check
L27 · 03
Payload fit

Insert without forcing or damaging it.

Size limit

Confirm 15 × 15 × 15 cm before testing.

Joint quality

No loose parts that should already be secure.

Record

List any last build change before the test.

Short finishing window only.Then testing begins
Standard Test
Same conditions = useful comparison
L27 · 04
Teacher Standard Test

Use the payload and drop condition announced at the start of the challenge. Place the payload correctly, close / prepare the package as designed, run one controlled test, then inspect the payload and solution.

Teacher-only: test one project at a time in a designated area. If using a breakable payload, contain fragments and follow normal cleanup/safety procedures.
Students record the actual result.Do not alter test conditions after seeing another result
Test Evidence
What counts as “functioning as intended”?
L27 · 05
Payload

Intact or damaged?

Package

Stayed together enough to complete its intended job?

Access

Can the payload be removed after testing?

IMPORTANT

A failed test is still valid evidence. Do not change the recorded result to match what you hoped would happen.

D-style habits are formative only.Evidence matters
Workshop
Finish → Test → Record

Test

Complete the final build evidence.

STEP 01

Finish

Use the short finishing window.

STEP 02

Test

Run the standard teacher test.

STEP 03

Record

Document result, function, and any final change already made.

Unit 3 Evidence Check
What should be in the design folder?
L27 · 07

Formal Unit 3 evidence.

B.i

Success criteria list.

B.ii–iv

Ideas, chosen design, planning drawing.

C.i

Creation plan with resources and time.

C.ii–iv

Technical making, functioning solution, change record.

Testing record supports evidence of function.Formal B + C unit
Unit 3 Reflection
Ideas became a physical solution
L27 · 08

Finish the unit with one insight.

“The biggest difference between an idea on paper and a solution I can actually build is _______.”

What comes next?

Unit 4 moves into sustainable design, material choices, creation, testing, and formal Criterion D evaluation.
