Carolina Leads the Way in Kits for AP® Biology!
  • First complete kits available for all 12 AP® Biology Labs
  • Developed in collaboration with leading experts
  • Flexible to fit your class size
Pioneering Innovation and Continuing Support - We were the first to offer kits specifically designed for each of the 12 AP® Biology Labs. Working closely with experts such as Dr. Bill Barstow, one of the original AP® Lab developers, we designed our kits to meet all the objectives of every lab. We have also revised our kit instructions to enhance clarity and provide questions that challenge students to think critically rather than memorize facts.

Our continuing support of AP® Biology includes loaning equipment and donating kits for teacher training at AP® Biology Summer Institutes. More teachers have been trained using out kits than those of any other supplier.
