| Explore | We know a lot now. We know that the mass of plants come from the air. We know that carbon is needed in photosynthesis. |
|---|---|
| Research Question | Does the amount of baking soda affect the rate of photosynthesis? |
| Predictions | The more baking soda added the faster the rate of photosynthesis. We think this will happen because of the carbon in the baking soda. |
| Experimental Design | I will first have two beakers with will have 12 leaf chips in a syringe and i will drown them using the vacuum effect. One beaker will have a pinch of baking soda and one will have three pinches of baking soda. I will then measure the speed of photosynthesis by measuring how many chips float through 15 minutes, and record to see if the amount of baking soda affects photosynthesis. |
| Conclusion | When we finished our experiment, we concluded that the amount of baking soda does in fact change the rate of photosynthesis. The leaf disks in the beaker with the most baking soda rose to the top the most. Future experiments could be done to prove this by like doing one with actual soda that you buy from the store and see what would happen if you used that. |
