process on earth, as this site explains.
Introduction to Photosynthesis
A description of the process, from Arizona State University.
Photosynthesis in the Classroom
A useful guide for teachers from the Science Ed Standards.
A lab exercise that enables your students to separate and study photosynthetic
chapter, students will read about the process of photosynthesis, which
captures the energy of sunlight to provide nearly all of the energy for
life on Earth. They will read about the major steps in this process, and
how it uses the energy of sunlight to convert water and carbon dioxide
gas into sugars that provide energy and structural material for the growth
and development of living things.The links below lead to additional resources

Section 8-1: Energy and Life
Plants and some
other types of organisms are able to use light energy from the sun to
The characteristics of ATP make it an
exceptionally useful molecule that is used by all types of cells as their
basic energy source.
Section 8-2: Photosynthesis: An Overview
The experiments performed by van Helmont,
Priestley, Ingenhousz, and other scientists reveal that in the presence
of light, plants transform carbon dioxide and water into carbohydrates
and release oxygen as a byproduct.
Photosynthesis uses the energy of sunlight
to convert water and carbon dioxide into oxygen and high-energy sugars.
In addition to water and carbon dioxide,
photosynthesis requires light and chlorophyll, a molecule found in chloroplasts.
Section 8-3: The Reactions of Photosynthesis
The process of photosynthesis includes
the light-dependent reactions as well as the Calvin cycle.
The light-dependent reactions produce
oxygen gas and convert ADP and NADP+ into ATP and NADPH. The light-dependent
reactions occur in different areas of the thylakoid, called photosystem
I and photosystem II.
The Calvin cycle uses ATP and NADPH from
the light-dependent reactions to produce high-energy sugars. The Calvin
cycle is also known as the light-independent reactions.
