Dr. Rebecca W. Keller received her PhD in biophysical chemistry from the University of New Mexico in 1992. She was then awarded a National Science Foundation postdoctoral fellowship in the Department of Molecular Biology at the University of New Mexico, followed by a Burroughs Wellcome Fund Postdoctoral Fellowship in the Department of Molecular Biology at the University of California, Berkeley. As Dr. Keller home schooled her three children, she was unable to find science textbooks that she felt would give her children a solid foundation in the sciences. Her scientific background, coupled with her desire to educate her children, led Dr. Keller to found Gravitas Publications, Inc. and to develop the Real Science-4-Kids curriculum. Real Science-4-Kids is a "worldview-neutral" curriculum that provides students with a solid foundation in the sciences and also gives them the tools to evaluate scientific data on their own. Students are presented with up-to-date scientific facts and the steps of the scientific method, together with the critical thinking tools needed to help them evaluate scientific conclusions. Dr. Keller's books are as philosophically neutral as possible and do not impose any single overall philosophical interpretation such as Darwinism, Intelligent Design, or Creationism. Instead, they allow students to make up their own minds about what the data show. Real Science-4-Kids, with its engaging, kid-friendly text and easy to use teacher-friendly manuals, is used in home, private, and public schools in all 50 states in the US and in many other countries. Dr. Keller's publishing team continues to develop and test products at her Albuquerque headquarters. The website for Real Science-4-Kids is www.gravitaspublications.com.
