Carolina Biological Supply Company began in 1927 when Thomas E. Powell, Jr., an Elon College professor who collected natural specimens for his class, discovered that he could sell surplus items to other teachers and professors. Dr. Powell soon realized that a team approach, with his company providing the centralized collection and distribution of educational materials, would free teachers to make better use of their time in the classroom and laboratory.
Carolina has formed just such a team with the National Science Resources Center to bring schools the Science and Technology for Children (STC) program. Developed and tested by teachers, STC is an inquiry-centered elementary curriculum that involves students in hands-on learning. Wisconsin Fast Plants Teaching Materials is another example of how the team approach benefits you.
