Below are sample questions representative of the exercises included on this worksheet and related 5.76 Plan and Conduct Fair Tests Iterate skill assessments:

Problem 1Difficulty: Mastery

Which complete plan best matches NGSS engineering design work for fair tests and iteration?

AChange many features in every test, use different conditions each time, and decide the winner by opinion.

BDefine what the prototype should do, change one variable at a time in fair tests, record measurements and failure points, use evidence to improve the model, and retest the improved version.

CMeasure only after the class has already selected the best-looking prototype.

DBuild the first idea, choose it as final, and avoid recording failure points so the project looks successful.

Solution & Explanation:The standard emphasizes fair testing, controlled variables, failure points, and using results to improve models or prototypes through iteration.

Problem 2Difficulty: Mastery

Use the planned filter results chart. The goal is water that is clear and filters in 6 minutes or less. Which next iteration is best supported?

ARevise Filter B to improve clarity while keeping its fast flow feature, then retest.

BChoose Filter A without changes because it is clearest even though it takes too long.

CChoose Filter C without changes because it is fastest even though it is cloudy.

DChange filter material, water amount, and pouring speed together before retesting.

Solution & Explanation:The best iteration uses evidence from both criteria. Filter B is fast enough but needs better clarity, so improving that part while keeping its speed is targeted.

Problem 3Difficulty: Mastery

A model shade structure is meant to protect a playground bench at noon. Why should the team test each prototype with the lamp in the same position?

AThe lamp position matters only after the final design is chosen.

BThe lamp position is the only result the team should measure.

CChanging lamp position helps every prototype win once.

DLight position affects shadow size, so it must be controlled to compare shade designs.

Solution & Explanation:If the light source moves, shadow size can change even if the design does not. A controlled lamp position makes the comparison fair.

This worksheet is designed specifically for Grade 5 Science students. It aligns with educational standard 3-5-ETS1-3 (NGSS 3-5-ETS1-3: Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved. Skill focus: choose models or diagrams that best test fair investigations by controlling variables, identifying failure points, and using results to improve a model or prototype. Associated standards: SEP Planning and Carrying Out Investigations; CCC Cause and Effect; CCSS MP.2 and 5.MD.B.2.).
