This resource focuses on the concept of natural selection and its role in evolution. It begins with a clear learning goal where students explain how natural selection leads to evolution by analyzing adaptations, selective pressures, and changes in populations. Key vocabulary terms are defined, including natural selection, adaptation, evolution, and selective pressure, to aid in understanding the core concepts. A case study on Darwin’s Finches illustrates how different beak shapes among finches, shaped by available food sources, led to distinct species through natural selection. Scenarios involving predation, climate change, and resource competition are used to analyze how environmental factors influence the survival of certain traits. Students engage in data analysis to observe how beak size in a bird population changes over generations due to selective pressures. Finally, guidelines for reflection and self-assessment are provided to help students connect their learning to the broader implications of evolution.
