Below are sample questions representative of the exercises included on this worksheet and related 3.67 Choose Materials for Purpose skill assessments:

Problem 1Difficulty: Mastery

A plant-pot coaster should soak up extra water from the pot, but it must stay firm enough to keep the pot level.Scores (1 = low, 5 = high):Coaster 1: Rigidity 2, Flexibility 4, Strength 3, Absorbency 5Coaster 2: Rigidity 4, Flexibility 2, Strength 4, Absorbency 1Coaster 3: Rigidity 3, Flexibility 3, Strength 4, Absorbency 4Coaster 4: Rigidity 1, Flexibility 5, Strength 2, Absorbency 5

It needs Absorbency ≥ 4, Strength ≥ 4, and Rigidity ≥ 3 so it does not collapse. Which coaster is best?

ACoaster 3

BCoaster 2

CCoaster 1

DCoaster 4

Solution & Explanation:Coaster C meets absorbency 4, strength 4, and rigidity 3. Coaster A absorbs well but is not rigid/strong enough. Coaster B is rigid and strong but not absorbent. Coaster D is absorbent but too weak and not rigid.

Problem 2Difficulty: Mastery

A towel hook is tested in a locker room.Scores (1 = low, 5 = high):Hook 1: Rigidity 5, Flexibility 1, Strength 5, Absorbency 1Hook 2: Rigidity 4, Flexibility 2, Strength 3, Absorbency 1Hook 3: Rigidity 3, Flexibility 3, Strength 4, Absorbency 2Hook 4: Rigidity 2, Flexibility 5, Strength 4, Absorbency 1

The hook must be rigid (Rigidity ≥ 4), very strong (Strength ≥ 5), and low absorbency (Absorbency ≤ 2). Which hook should you choose?

AHook 4

BHook 2

CHook 1

DHook 3

Solution & Explanation:Hook 1 is the only option with strength 5 and rigidity 5 while keeping absorbency low (1). The other hooks fail either strength or rigidity.

Problem 3Difficulty: Mastery

A science fair display board must stand straight and hold posters.Scores (1 = low, 5 = high):Board X: Rigidity 5, Flexibility 1, Strength 4, Absorbency 4Board Y: Rigidity 4, Flexibility 2, Strength 4, Absorbency 1Board Z: Rigidity 3, Flexibility 3, Strength 5, Absorbency 1Board W: Rigidity 2, Flexibility 5, Strength 3, Absorbency 1

It needs Rigidity ≥ 4, Strength ≥ 4, and low absorbency (Absorbency ≤ 2) so it won't warp if the room is humid. Which board is best?

ABoard Z

BBoard X

CBoard W

DBoard Y

Solution & Explanation:Board Y meets rigidity 4, strength 4, and absorbency 1. Board X is rigid but too absorbent (4). Board Z is not rigid enough (3). Board W is not rigid or strong enough.
