What affects the beak length of Island Scrub-jays on Santa Cruz Island?

The storyline in this STEM kit has students studying the Island Scrub-Jays which separated from mainland scrub-jays almost a million years ago and have some interesting differences now. Students will study the bird’s beak shape and size, their feeding performance, vocalizations and heritable traits to understand off-spring survival rates. Drs. Rebecca Cheek and Cameron Ghalambor helped develop this STEM kit.

Science and Engineering Practices include: 1) developing and using models; 2) analyzing and interpreting data; 3) using mathematics and computational data; 4) obtaining, evaluating, and communicating information

Crosscutting Concepts include: 1) patterns; 2) cause and effect; 3) scale, proportion, and quantity; 4) systems and system models; 5) stability and change in systems
