Wow, I ordered these at least 10 years ago and I didn’t know it was still available. The Howard Hughes Medical Institute has tons of DVDs and other materials you can order for 100% free! No CC needed, but you do need to create an account!
These are very high quality. They are great for your reference library, and for home-schooled High School aged children. And once you are on the mailing list, you get a high quality BIG science magazine free in the mail several times a year. Go to This Page to start ordering!
