Activity: Gizmo - Rainfall & Bird Beaks

Objective

Overview

Materials

● The Rainfall and Bird Beaks Gizmo™ allows students to explore how climate affects population size and the distribution of beak shapes

● Gizmo

● Observe fnch populations and beak shapes during normal years. ● Understand how annual rainfall affects the amount and types of available seeds. ● Explore how fnch populations change in times of drought and excess rainfall. ● Identify examples of directional and stabilizing selection. Explain how new species of fnches could arise.
