Photosynthesis Experiment on the different colors of light using cellophane Research Question: How does the color of the light shining into the Cabomba plant affect the amount of O2 bubbles produced? Carbon dioxide reacts with water to form glucose and sugar. That is how photosynthesis works. Plants go through photosynthesis to make sugar for themselves and be able to absorb CO2. It is like a cycle. The thing that we are measuring for this experiment is the amount of oxygen released through bubbles. We are testing to see how each color of the light affects the affects the amount of the oxygen produced, so we have to observe the amount of tiny bubbles that come up in each color of light. Hypothesis: I predict that the darker the color of the light, the less amount of sugar will be produced. This is because if the amount of light decreases, the amount of photosynthesis will also decrease. If the light increases, photosynthesis will also increase. Bubbles are oxygen, which are released during the light reaction of the plant during photosynthesis. In the first step of photosynthesis, the plants take the energy captured by sunlight by chlorophyll, then releasing oxygen as a byproduct. For plants, photosynthesis takes place in organelles called chloroplasts. Photosynthesis is usually a two-step process. In the first step, the light reaction, the providing the ATP molecule is synthesized using the light energy that was absorbed by chlorophyll. The water is then broken into oxygen and hydrogen ion, the with hydrogen electron being transferred into another energy molecule, NADPH. The second step is when the ATP and NADPH molecules power the transfer of electrons. Carbon is then broken away from carbon dioxide and combined with oxygen to create carbohydrates. Control Variables: Mass of the plant: Mass can affect the photosynthesis of any type of plant. The
