In this detailed and comprehensive multi-day activity, budding evolutionary biologists use real data from lizard populations in the Canary Islands to examine evolution and natural selection. 

High schoolers become birds and are given "beak-types". After completing the simulation, students relate results to adaptations and natural selection. Extensions of the simulation allow for comparative results and include population...

Tenth graders explore structure, function and variation among species. Through field observations, lab activities and homework, 10th graders observe and record examples of adaptation and variation.
