“Classroom Variation” is an interactive activity designed to explore the concept of genetic diversity among individuals in a classroom setting. In this activity, students use a meterstick to measure the length from their elbow to the tip of their middle finger. Each student's measurement represents a unique trait, and they record their data on a chart or graph. The data is then analyzed collectively to observe the range of measurements within the class.

By graphing the data, students visually represent the variation in arm length among their peers. Through discussion, students explore possible factors contributing to this variation, including genetic inheritance, environmental influences, and random variation.

This activity not only provides a hands-on experience in data collection and analysis but also fosters critical thinking about the complexities of genetic diversity within a population
