Created by the Concord Consortium with support from the National Science Foundation, the goal of the Molecular Logic website is "to develop students' understanding of molecules, their interactions and the consequences of these interactions." The researchers and specialists in charge of the site have selected ten physical-chemical principles that underlie many biological processes. They call them "Molecular Stepping Stones", and the site includes entry-level model-based activities for each of these steps. Some of the steps have multiple parts, and visitors will note that each section includes an interactive activity and notes for teachers. Some of the subjects covered here include molecular folding, chemical reactions, and the structure and function in proteins.
