Abstract: Provided is a method and apparatus for teaching biology by using a virtual plant or a virtual animal. The method is displayed on a display of a computer and includes collecting growth data of an actual living organism according to different environmental conditions at a predetermined time interval and storing the collected growth data; obtaining a growth equation for each of the environmental conditions based on the growth data; designing a growth animation of the virtual living organism for each of the environmental conditions based on the growth equation; and controlling a control panel screen to fetch the growth data and the growth animation and to display a change in growth of the virtual living organism when a user inputs environmental conditions of the virtual living organism on the control panel screen, to thereby provide high practicality and high educational effects.
