This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell. By analyzing four sand-filled cubic models (made from heavy paper), learners can find answers to many questions about cell growth. This lesson guide includes fifteen sample questions with answers.
