| Research Question | How does red plastic wrap affect photosynthesis? We came up with the question because we recently just learned about pigments and how chlorophyll uses them and want to experiment the affect of it. The question fits with the topic because chloroplast contains chlorophyll, which is where photosynthesis takes place. |
| Predictions | The possible outcome of our study would be that there would be more leaf disks floating in red light than regular sunlight. We believe this will happen because leafs are prone to absorbing red light faster. |
| Experimental Design | To start of the experiment we have to have two cups that contain the same amount of water and baking soda, with having the baking soda in the water it will provide the water with carbon dioxide. By having the carbon dioxide, water and light will do the process of photosynthesis. Then, we will to remove 10 leaf disks with hole punchers to have in each cup. We will then put the leaf disks in the syringes with water will create oxygen and allow the leaf disks to float to the bottom. Then we will put the red wrap and no wrap cups under the same light for 20 mins, we will check every minute how many leaf disks float. We will record our data in a chart for amount of leaf disks that float every minute. |
