What is Inquiry?
Good science education requires both learning scientific concepts and developing scientific thinking skills. Inquiry is an approach to learning that involves a process of exploring the natural or material world, and that leads to asking questions, making discoveries, and testing those discoveries in the search for new understanding. Inquiry, as it relates to science education, should mirror as closely as possible the enterprise of doing real science.

Prion Problem Space
Prions are relatively small proteins that display dramatically alternate conformations for similar primary structures. Abnormal conformations appear to cause fatal neurological diseases in a wide variety of mammals. Researchers are discovering the mechanisms behind these conformational changes, including differences that may lead to species barriers (or lack thereof) among exposed animals. How do these conformations differ? How do small sequence differences affect susceptibility to conformationa
