Below are sample questions representative of the exercises included on this worksheet and related 5.78 Justify a Solution with Claims, Evidence, and Reasoning skill assessments:

Problem 1Difficulty: Mastery

Problem: keep a plant watered over a weekend. Test evidence: A wick system from a small reservoir delivers water slowly to the soil. Tradeoff: the team must consider strength, time, and material use. Which justification uses claim, evidence, and reasoning?

AConsidering the tradeoffs, claim: The sealed empty cup is best for keeping a plant watered over a weekend because it seems interesting, even without evidence.

BConsidering the tradeoffs, evidence is not needed when a design for keeping a plant watered over a weekend looks easy to build.

CConsidering the tradeoffs, the dry paper towel must be best for keeping a plant watered over a weekend because it was listed as another option.

DConsidering the tradeoffs, claim: The wick system from a small reservoir is the strongest solution for keeping a plant watered over a weekend. Evidence: tests showed it delivers water slowly to the soil. Reasoning: that result matches the design goal and constraints.

Solution & Explanation:A strong justification includes a claim, specific test evidence, and reasoning that connects the evidence to the design goal and constraints.

Problem 2Difficulty: Mastery

Problem: make a model boat carry coins. Test evidence: A wide foil boat with raised sides displaces water and resists tipping. Tradeoff: the team must consider strength, time, and material use. Which justification uses claim, evidence, and reasoning?

AConsidering the tradeoffs, claim: The solid clay ball is best for making a model boat carry coins because it seems interesting, even without evidence.

BConsidering the tradeoffs, evidence is not needed when a design for making a model boat carry coins looks easy to build.

CConsidering the tradeoffs, claim: The wide foil boat with raised sides is the strongest solution for making a model boat carry coins. Evidence: tests showed it displaces water and resists tipping. Reasoning: that result matches the design goal and constraints.

DConsidering the tradeoffs, the narrow flat strip of foil must be best for making a model boat carry coins because it was listed as another option.

Solution & Explanation:A strong justification includes a claim, specific test evidence, and reasoning that connects the evidence to the design goal and constraints.

Problem 3Difficulty: Mastery

Problem: create a hand-washing reminder. Test evidence: A waterproof sign near the sink with simple steps communicates clearly where students need it. Tradeoff: the team must consider strength, time, and material use. Which justification uses claim, evidence, and reasoning?

AConsidering the tradeoffs, claim: The tiny sign behind a door is best for creating a hand-washing reminder because it seems interesting, even without evidence.

BConsidering the tradeoffs, claim: The waterproof sign near the sink with simple steps is the strongest solution for creating a hand-washing reminder. Evidence: tests showed it communicates clearly where students need it. Reasoning: that result matches the design goal and constraints.

CConsidering the tradeoffs, evidence is not needed when a design for creating a hand-washing reminder looks easy to build.

DConsidering the tradeoffs, the long paragraph in the hallway must be best for creating a hand-washing reminder because it was listed as another option.

Solution & Explanation:A strong justification includes a claim, specific test evidence, and reasoning that connects the evidence to the design goal and constraints.
