Below are sample questions representative of the exercises included on this worksheet and related 8.05 Designing Reproducible Procedures skill assessments:

Problem 1Difficulty: Mastery

Which protocol would another class be most likely to reproduce when investigating how shade affects local air temperature?

APlace identical thermometers 1 m above the ground in 3 sunny locations and 3 shaded locations, record temperature at the same times each day for 5 days, and average the readings for each condition.

BMeasure temperatures at random times in any sunny and shady places you find.

CChoose the hottest sunny place and the coolest shady place for the biggest difference.

DUse different kinds of thermometers in each location to get more variety.

Solution & Explanation:The plan fixes thermometer height, sample size, timing, and duration while comparing sunny and shaded conditions fairly.

Problem 2Difficulty: Mastery

A class is comparing how well different deicers melt ice. Which protocol is most reproducible?

AUse different sizes of ice cubes for different deicers so the test finishes faster.

BJudge which deicer seems strongest by looking at the tray.

CAdd extra deicer to the slowest tray.

DPlace equal-mass ice cubes in identical trays, add 10 g of each deicer, and measure melted water volume every 2 minutes for 20 minutes.

Solution & Explanation:The procedure controls ice mass and tray type, uses equal deicer amounts, and records a measurable outcome on a fixed schedule.

Problem 3Difficulty: Mastery

A group is studying sound reflection in school hallways. Which change most improves reproducibility when background noise could affect the results?

AUse any hallway and clap whenever it seems quiet.

BUse the same speaker volume in each hallway, place a sound meter 5 m from the speaker and 1.5 m above the floor, and record reflected sound level in 3 trials during a time with low background noise.

CAsk students which hallway has the biggest echo.

DChange both the volume and the hallway length in each trial.

Solution & Explanation:A fixed sound source, fixed meter position, repeated trials, and a consistent low-noise time improve reproducibility.
