Bozeman Science

This site has hundreds of video lectures on high school and AP level science topics. There are pdf concept maps and slideshows to accompany all videos, and a few printable review questions as well. They appear to be of good quality, and they're free!

Centripetal Press

This company publishes science text books that are different from most others. The goal of the books is to teach mastery, avoiding the "cram-pass-forget" cycle, and encouraging deeper learning. The prices are fairly reasonable and materials are available in printed or e-book form.
