Image Description
Screen shot from the Photosynthesis Prototype.
Photosynthesis Explorer Screen. Directions for exploring the effects of
light intensity appear in a box located in the upper left corner.
Underneath is a graph with a vertical bar containing ten-point graduations,
and a horizontal bar labeled "time." The graph has two variable lines:
sugar and oxygen. As the user adjusts various controls, the lines change.
In the upper right corner, a box contains six input controls, listed in two
columns. The left column reads: Humidity, Light Intensity, Oxygen in Air.
The right column reads: Temperature, Carbon Dioxide in Air, and Water
Intake Rate. An image of a leaf appears underneath the control box. Three
selectable buttons stretch along the bottom of the screen, labeled Sugar,
Oxygen, and Sugar plus Oxygen.
