It is a small, independent publishing company specializing in quality educational materials for children and adults. Dr. Rebecca W. Keller was working as research assistant professor after receiving her Ph.D. in biophysical chemistry from the University of New Mexico. For years, she worked in the areas of biophysics, molecular biology and neuroscience. She also home schooled for her three children for 14 years in her Albuquerque, New Mexico, home. When she could not find textbooks that excited her kids about science, she began to create her own. Eventually she founded Gravitas and wrote the hugely popular Real Science-4-Kids science books and the Kogs-4-Kids workbook series. Gravitas believes in teaching for understanding ' and for fun!
