Example FRQ and Scoring Guidelines

Let's consider a sample FRQ and a simplified scoring guideline to illustrate the process:

Sample FRQ:

*Scientists are studying a population of butterflies in a meadow. They observe that some butterflies have a darker wing color than others. They hypothesize that the darker wing color provides better camouflage against predators.

(a) Describe an experiment to test the scientists' hypothesis. Be sure to include a control group, independent variable, and dependent variable.

(b) Predict the results of the experiment if the hypothesis is supported. Explain your reasoning.

(c) Describe one potential source of error in the experiment and explain how it could affect the results.*

Simplified Scoring Guideline:

(a) Experiment Description (4 points)

• Control Group: (1 point) A group of butterflies with light wing color.
• Independent Variable: (1 point) Wing color (dark vs. light).
• Dependent Variable: (1 point) Survival rate (or predation rate).
• Procedure: (1 point) Detailed and logical procedure for observing predation rates in both groups.

(b) Prediction and Reasoning (3 points)

• Prediction: (1 point) Butterflies with darker wings will have a higher survival rate.
• Reasoning: (2 points) Explanation that darker wings provide better camouflage, making the butterflies less visible to predators.

(c) Source of Error (2 points)

• Identification: (1 point) Identifying a potential source of error, such as variations in predator behavior or environmental conditions.
• Explanation: (1 point) Explaining how the error could affect the results, such as leading to an overestimation or underestimation of the survival rate.

This example demonstrates how the scoring rubric breaks down the question into specific components and assigns points based on the accuracy and completeness of the answer.
