We are testing different watt light bulbs and how it affects how fast the chads rise. We are using 300, 200, 100 and 60 watt lights bulbs. We are timing how long it takes for the chads to rise with each different light.
Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy. Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy. The input is carbon dioxide (CO2), water (H2O), minerals and light, and the output is carbohydrates (food) that we need for our nourishment

Measure 1g of baking soda and mix it in with the distilled water. Take spinach leaves and hole puncher, punch out 12 circles from the spinach leaves. These small cut out circles are called chads. Once you have cut out your chad's take the syringe and place 12 chads in it. Draw the baking soda water from the cup into the syringe. Once the syringe is filled with the water, the chads will float to the top. slowly press the syringe plunger until the air is out of the syringe. Place your thumb over the tip of the syringe and pull back on the plunger. While holding the syringe like this, move the syringe in a circular movement for 10 seconds, repeat this till all the chads sink to the bottom. After all chad's have sank squeeze the water from the syringe back into the cup you drew it out from. Place the chads in the cup that you drew your syringe water from. Take a clear bowl that is larger than the cup your chads are in and fill it with tap water. Place the larger bowl on top of the smaller cup with the chads. Make sure there are no lights on in the room while you are performing this experiment. Take some sort of platform with a base, pole and a clamp to attach a lamp too. Place the 60W light bulb in the lamp. Take the ruler and measure 9 inches from the tip of the bulb to the base of the stand. Have stop watch ready and a device with Google spreadsheets or Excel on it to record data. Turn the lamp on and start the
