| Explore | We know that plants produce oxygen and they take in carbon dioxide. Photosynthesis occurs in plants. We have discussed photosynthesis and cellular respiration and discovered the differences. A question that interests us about plants is how some plants can grow under intense conditions. |
|---|---|
| Research Question | We want to test how temperatures affect photosynthesis. |
| Predictions | The possible outcomes of our study will show us how different plants thrive under different temperatures. So an outcome could be that a daffodil's rate of photosynthesis is faster with cold water. We think that because temperature effects photosynthesis. |
| Experimental Design | We plan on testing the rate of photosynthesis of a daffodil and rhododendron leaves through the temperature of water. We used regular water, ice water, and boiling water. We ran 3 different trials on each leaf with the 3 different temperatures of water. The constant variable would beg the 2 different types of leaves. We will record our data through a graph. |
| Conclusion | We can claim that the rate of photosynthesis is definitely affected by the temperature of water. Possible explanations from our results could be that the sun is a major factor of photosynthesis, and using hot water is a source of heat, so the rate could be faster. Our data shows that the hot water bath had the faster rate of photosynthesis because the leaves came up quicker. A future experiment that could expand on the results of this experiment is growing plants and watering them with different temps of water. |
