Why do plants need light?
Lesson Objectives...
Obtain, evaluate, and communicate information to show the relationships among matter and energy between the inputs and outputs for the process by which plants use energy from light to make sugars from carbon dioxide and water (photosynthesis).
Engage in argument from evidence and scientific reasoning to support the claim that plants use sunlight for energy to convert carbon dioxide and water into sugar that provides a form of energy the body can use.

What we figured out this lesson...
Water and carbon dioxide don't provide energy (measured in calories) for the body, but glucose does.
The plant must be getting energy from the light.
Plants must use sunlight as an input for energy so that they can do chemical reactions to make sugar (glucose and other complex food molecules).
