| Explore | We know that plants need sunlight and water in order to grow. That photosynthesis is huge part of the plants growth and development. How have plants evolved throughout time? |

| Research Question | How temperature effects the rate of photosynthesis? We were interested in seeing how this can relate to climate change. We know that photosynthesis is affected by many ways and we think that temperature is one of those factors. |
| Predictions | Some of the possible outcomes that will come from changing the temperature of the water are that photosynthesis will occur either faster or slower. We think that the lower the temperature, the longer it will take for photosynthesis to occur. We think that this will happen because of denaturing. |
| Experimental Design | How does temperature affect the amount of leaf disks that rise to the surface in a baking soda solution? Materials List: Leaves Hole puncher Syringe Eight cups Water at 4 different temperatures: 4°C, 37°C, 55°C, 95°C Light lamp Stick on Labels Sharpie Baking Soda Detergent Solution(Tiny bit) Timer Protocal: Gather all of the materials above. Put one of the temperatures of water into one of the cups and add baking soda. Take a label and label the cup with the temperature of water that you put in. Take a leaf and cut out 10 hole punches. Take the leaf hole punches and put them into the syringe. Fill the syringe with the solution that you put into the cup and put your thumb over the top and pull down on the syringe. So this until the leaves start to sink to the bottom. Once all of the leaves have fallen to the bottom dump the leaves into the solution and put the solution under the light lamp. After every minute record how many leaves have risen to the surface. Keep recording the amount of leaves risen for 15 minutes. Repeat this experiment with the rest of the temperatures. |
