Institutions who have NSF grants must offer outreach programs. I will show links to the various outreach programs here at Cornell because I know Cornell best! But, other instituions also offer lesson plans that have been written as part of their outreach programs. For example:
Columbia University Summer Research Program for Science for Teachers–lesson plans
Below I list a few of the programs at Cornell. My point is–explore your home institution for similar resources.
Research Experience for Teachers–RET Modules
Labatory for Elementary-Particle Physics– teacher materials
Cornell Science Inquiry Partnerships –curriculum resources
Cornell Institute for Physics Teachers –labs & lending library
Cornell University Center for Advanced Computing — math and science gateway
