This exercise is designed to review the scientific method and introduce you to the cell as the fundamental unit of life. You should understand the activity of science, the concept of testing what we believe to be true and changing our minds when we are proven wrong. The cell is an appropriate place to start a course of biology--to understand life in a useful and meaningful way, you have to understand the cell. We will show how an experimental approach has allowed great progress in understanding the lives of cells.

This resource is part of the Biology Links for One Laptop Per Child course which contains units on Exploring Life; The Cell; Genetics; Mechanisms of Evolution; The Evolutionary History of Biological Diversity; Plant Form and Function; Animal Form and Function; Ecology; and Astrobiology.
