Task PreScreener: Finch Beak Adaptation & Form

This document evaluates the Finch Beak Adaptation & Form task based on the Task PreScreener criteria to ensure alignment with NGSS standards.

1. Is it a task?

Evaluation: Yes. The activity requires students to interact with a simulation, gather specific data across different environmental conditions, and use that evidence to make sense of the phenomenon of adaptation. The analysis section asks them to construct an explanation based on the principles of natural selection, moving beyond simple recall of definitions to active sensemaking.

2. Is it multidimensional?

Evaluation: Yes.

• Science and Engineering Practice (SEP): Constructing Explanations and Designing Solutions (students are explicitly asked to construct an explanation based on evidence for how natural selection leads to adaptation).
• Disciplinary Core Idea (DCI): LS4.C: Adaptation (students explore how environmental changes affect the distribution of traits in a population).
• Crosscutting Concept (CCC): Cause and Effect (students analyze the relationship between rainfall levels, seed availability, and changes in the physical form of the finches).

The task seamlessly integrates these three dimensions by having students use the SEP to explain the DCI through the lens of the CCC.

3. Are the scenarios engaging, relevant, and accessible?

Evaluation: Yes.

The task uses a clear, classic example of natural selection (Darwin’s Finches) modeled in an interactive simulation. The visual representation of beak sizes and seed availability makes abstract concepts like natural selection and adaptation accessible to 10th-grade biology students. The scenario is engaging as students control the environment and observe the immediate effects on the population over generations.

Conclusion: The task passes the PreScreener with no red flags. It is appropriate for further development and implementation in a 10th-grade biology classroom targeting HS-LS4-4.
