What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively?
Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis.
Background Information:
Photosynthesis is the process in which plants use light energy to transform into chemical energy. The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy. Predators then eat the animals who eat the plants and each

Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.
Hypothesis: If four lights (UV Light, LED Light, Infrared Light, and Blue Light) are used to perform photosynthesis on a spinach leaf, then the spinach will respond most to the blue light and perform a more efficient photosynthetic process.
