At Home Science

appropriate for grades 6-12~ a site that has exploration into the world of microbes and bacteria through webquests and activities.

Science Curriculum education children educational homeschool. SOme sections have not been completed yet.

You can access the material even without giving them your email. Not all areas have been completed. Even though it says K-12, I don't see high school material.

Not a reliable source of information. In Scientific Origins section, states on first page that notion of population sorting mentioned in bible when God condemned the Amalekites for their depravity, yet it makes NO mention of Darwin at all. "Eugenics" coined in 1880's and logo is tree with motto about it being the self-direction of human evolution, with the first and most prominent root being genetics.

so much here for teaching about this topic~ there is also a teaching section for further links for learning ~ a great resource, so comprehensive it might be safe to say it could be a one stop site because it brings you along to so many other resources

My son could probably get lost in this site~ a chronological timeline of the story of DNA, interactives in learning about DNA along with lesson plans etc..

somewhat interactive, click on the element to learn more~ also allows for printable periodic tables

a site I came across appropriate for upper grade levels, an abundance of information here from the compound library, to quiz's,interactives, articles, glossary, a great resource for chemistry
