The National Academies (including the National Academy of Science) in cooperation with several other groups are working on new science education standards that they intend will be adopted by all states. A major goal of such a project is to consolidate the many different sets of state science standards that arose in the wake of the original National Science Education Standards published about a decade and a half ago.

There is currently a call for comments on these standards and I heartily encourage you to read the current draft and send your comments. Here are relevant URLs

The NSDL Science Literacy Maps are a set of guidelines for what science should be learned at what level that may be useful to consult.
