Below are sample questions representative of the exercises included on this worksheet and related 5.43 Design and Conduct a Plant Growth Investigation skill assessments:

Problem 1Difficulty: Mastery

After 2 weeks, plants under green light are shorter. Another student points out the green light bulb was dimmer than the others.

What is the best next step?

AConclude green light is always worse and stop.

BRemove the dim bulb data and keep only the tallest plants.

CChange water amounts instead.

DMeasure and match light intensity across colors, then retest color with intensity controlled.

Solution & Explanation:To test color, intensity must be controlled; otherwise the difference might be due to brightness, not color.

Problem 2Difficulty: Mastery

A student argues that the class should randomize which seedlings go into which group.

Why is random assignment helpful?

AIt makes data tables unnecessary.

BIt guarantees every plant grows the same.

CIt reduces bias by making it less likely that stronger seedlings end up in one group on purpose.

DIt changes the independent variable automatically.

Solution & Explanation:Random assignment helps groups start similar on average, improving fairness and reducing selection bias.

Problem 3Difficulty: Mastery

Growth data (cm) in 10 days: Group 1 (sand): 2, 3, 3, 4 Group 2 (mix): 3, 4, 4, 5 Group 3 (potting): 4, 5, 5, 6

Which statement is the best claim supported by these data?

ASoil type never matters because all groups grew.

BIn this test, growth increased from sand to mix to potting mix.

CPotting mix caused growth to stop.

DSand always produces the best growth for all plants.

Solution & Explanation:The typical values increase from sand to mix to potting, supporting a claim of greater growth with those soil types in this setup.
