Overview:

Hairs don't have nerves, or eyes but if they aren't cut they will always grow out to the same length. Each kind of hair grows to their own length. How do hairs "know" when to stop growing? The students are introduced to the observed growth rates and lengths of phases in the hair growth cycle. Using computer models they compare these factors to develop a theory to explain how hairs "know" when to stop growing. 

As they work through the process they are introduced to the scientific concepts of verification and validation. As scientists we need to verify that we have followed the directions correctly, i.e., did we put the right numbers into the equation? Scientists also need to validate their conclusions. "Is the answer reasonable? Did I use the correct equation?"
