**What This Document Is**
This document is a student exploration worksheet accompanying a Gizmos simulation titled “Rainfall and Bird Beaks.” It’s designed for a Molecular Biology course (BP 723) at Harvard University and focuses on applying concepts of natural selection and adaptation using a virtual environment. The worksheet guides students through an investigation of how rainfall patterns influence beak depth in a finch population, mirroring Charles Darwin’s observations in the Galapagos Islands.
**Why This Document Matters**
This study guide is intended for Harvard University students enrolled in Molecular Biology (BP 723). It’s used as a lab exercise to reinforce understanding of evolutionary principles, specifically how environmental pressures drive changes in populations. Students will utilize the Gizmos simulation to collect and analyze data, then answer questions to demonstrate their comprehension of the relationship between rainfall, seed availability, and finch beak morphology. It’s typically used during a lab session or as a homework assignment to solidify learning.
**Common Limitations or Challenges**
This document is a *supplement* to the Gizmos simulation; it does not contain the simulation itself. It provides questions and prompts for analysis, but students must independently interact with the Gizmo to gather the necessary data. The worksheet focuses on observation and initial interpretation, and doesn’t delve into advanced statistical analysis or detailed genetic mechanisms. It’s a starting point for understanding natural selection, not a comprehensive treatment of the topic.
**What This Document Provides**
This document includes:
* Prior Knowledge Questions relating to Darwin’s finches and beak adaptations.
* Guided questions for the “Gizmo Warm-up” section, introducing the simulation interface.
* Activity A, exploring the impact of average rainfall on finch populations and beak depth.
* Activity B, investigating the effects of drought conditions.
* Questions prompting observation, analysis, and hypothesis formation.
This preview *does not* include the answers to the questions, the full dataset generated by the Gizmos simulation, or the Assessment Questions available within the Gizmo itself. It also does not include the interactive simulation component.
