Below are sample questions representative of the exercises included on this worksheet and related 3.61 Define Design Problems Clearly skill assessments:

Problem 1Difficulty: Mastery

A laptop power cord crosses a walkway and could trip someone. The class wants a cover that reduces tripping and protects the cord.Pick the problem statement that best matches the classroom cord-trip cover challenge and includes limits on materials, time, or cost.

ADesign a cover for the cord so people don't trip.

BDesign a cover that protects the cord using foam and tape.

CDefine the problem: Design a cord cover that keeps the cord flat so a toy cart can roll over it 10 times without snagging. Constraints: cover must be under 2 cm tall, use only foam strip and tape, cost $4 or less, and be installed in 20 minutes.

DDesign a cord cover that stays under 2 cm tall and lets a cart roll over 10 times without snagging, using foam strip and tape only, costs $4 or less, installed in 20 minutes.

Solution & Explanation:The correct statement includes a measurable performance test (cart rolls over 10 times) and constraints (height, materials, cost, time).

Problem 2Difficulty: Mastery

At a science fair, posters sometimes fall over when people walk by. Students want a stand that holds a poster safely.Which choice clearly defines the design problem for the science fair poster stand, including criteria and constraints?

ADesign a stand for science fair posters so they don't fall.

BDesign a stand that holds a poster upright and is foldable, using cardboard.

CBest problem statement: Design a stand that holds a 60×90 cm poster upright and stays standing during a 10‑second fan test. Constraints: it must fold flat to 5 cm thick, use only cardboard and string, cost $7 or less, and be built in 90 minutes.

DDesign a stand that holds a 60×90 cm poster and stays standing in a fan test, folds to 5 cm thick, uses cardboard and string only, costs $7 or less, built in 90 minutes.

Solution & Explanation:The correct statement includes measurable criteria (poster size, fan test, fold thickness) and constraints (materials, cost, time).

Problem 3Difficulty: Mastery

Some students write more neatly when the paper is tilted. The class will design a slant board that helps writing without sliding.Which choice clearly defines the design problem for the handwriting slant board, including criteria and constraints?

ADefine the problem: Design a slant board that holds a sheet of paper at 20–30° and prevents the paper from sliding more than 1 cm during a 2‑minute writing test. Constraints: board must fit on a 40×30 cm desk, use only cardboard and rubber shelf liner, cost $5 or less, and be built in 60 minutes.

BDesign a board that tilts paper so handwriting is easier.

CDesign a slant board that tilts the paper and uses cardboard.

DDesign a slant board that holds paper at 20–30° and limits sliding to 1 cm in a 2‑minute test, fits the desk, uses cardboard and shelf liner only, costs $5 or less, built in 60 minutes.

Solution & Explanation:The correct statement has measurable criteria (angle range, slide limit) and constraints (size, materials, cost, time).
