Grass And Spinach Lab Report

Comparing the amount of carbon dioxide in the grass and spinach leafs
Photosynthesis is an important process that happens in plants and algae to get energy they need to function. In order for this process to happen carbon dioxide needs to be present. “Takes in the carbon dioxide produced by all breathing organisms” ( Vidyasagar). For this experiment that was studied with the group, it was trying to see which leaf produced more carbon dioxide, the spinach leaf or the grass. The hypothesis that was created for this experiment was that the grass will have higher levels of carbon dioxide and the spinach leafs will have lower levels. The null hypothesis is that there will be no difference between the grass and spinach leafs. The reason for this idea was because the grass grows all year long under the sun and spinach leaves grows only for a certain period of time under certain conditions. For this experiment we will be using carbon dioxide sensors to help us out with telling how much of it is

The experiment was repeated three times for ten minutes each. The materials that were used was two grams of spinach and grass leafs for every trial done, a lab quest for recording the information, lamp for light, two carbon dioxide sensors, two plastic bottles, and a scale to weight the materials. The experiment was started out by measuring two grams of the grass and spinach leaves on a scale. Then the products that were measured were put into two plastic bottles. Carbon dioxide sensors were plugged into each bottle and the lab quest. Next a lamp was put over the bottles for this process to give light or energy for the plants. The experiment was timed for ten minutes and repeated three times for ten minutes each. For every trial new grass and spinach was used. The treatment for the experiment is the grass and spinach leaf. When the experiment was done, the results were recorded and we got interesting
