Gravitas Publications Inc. 

Gravitas Publications Inc. is an independent publishing company and the parent company to Real Science-4-Kids. It began with Dr. Rebecca Keller’s desire to teach her little ones real science concepts and developed into a passion for helping all kids discover science. 

Dr. Keller has her PhD in biophysical chemistry from the University of New Mexico and worked as a lab scientist and assistant professor before founding Gravitas Publications and becoming a full-time CEO and author.

Today Real Science-4-Kids is helping kids achieve academic excellence in science in all 50 states of the US as well as Australia, New Zealand, Canada, Europe, Japan and Korea and other countries. Based in Albuquerque, New Mexico, Gravitas Publications has been inspiring the next generation of scientists since 2003. 

The Real Science-4-Kids Vision 

Our vision at Real Science-4-Kids is to help every child learn, understand, and use scientific facts and ideas to solve real-world problems. Our program introduces and then builds upon the basic building blocks students need in order to apply scientific thought and methods to answer real-world questions. We want the Real Science-4-Kids curriculum to reach every child so they can discover that it is possible for them to change the world with science.
