From crystallization to protein folding, basic biological and chemical processes depend on interactions among atoms and molecules. High school and beginning college students can study and manipulate these liaisons at Molecular Logic from the Concord Consortium, an educational nonprofit based in Massachusetts. A database furnishes scores of interactive activities that run with free software available from the site. For example, by moving a virtual protein from water to oil, users can observe how the type of solution modifies the molecule's folding. In water, hydrophobic amino acids jostle to reach the molecule's interior, but in oil the hydrophilic amino acids seek the center. Students can also explore the basis for techniques such as electrophoresis and Southern blotting.
