During the 1920s, science teachers had to collect most of the materials they used in their classes and laboratories, which took considerable time away from their primary responsibilities.
Like other teachers, Dr. Powell spent much of his own time in the field gathering specimens for his classes.
His efforts grew into Carolina Biological Supply Company, as Powell foresaw a need for his collecting abilities in the coming years.
Its business units include Carolina® Curriculum, offering K-8 hands-on science kits; Carolina Science Online®, an e-learning portal with digital resources; and Carolina Distance Learning®, offering college-level lab kits for distance education.
Carolina's website also offers free classroom activities and other resources for educators.
