Don't just tell your class about Darwin's finches ... show them! Sort some of science's most famous birds using an interactive lesson. Learners try their hand at classifying finches using song, sonogram, and beak appearance, as well as...

Build a bird by choosing specific structures to match the environment, then see how you did by calculating the survival rate.

Explore how environmental conditions affect the adaptation of birds in this simulation. The amount of annual precipitation on an island is controlled by you while you track changes in the thickness of bird beaks over a five-year period....

Can you identify the purpose of different bird beaks? Read up about the different types of beaks and then you'll apply your knowledge by identifying the purpose of different shaped beaks.

Interactive animation illustrates how Charles Darwin used his study of finch beaks to explain evolution. A phylogenetic tree diagram shows how the birds' color and beak shape changed over generations.
