Photosynthesis Lab - Hour 3 by Jeremy Mohn https://padlet.com/jmohn/osktwc4vclx3 Group 2 - Carbon Dioxide Concentration en-us 2016-10-15 20:40:23 UTC 2025-09-24 04:03:17 UTC hello@padlet.com http://d20uo2axdbh83k.cloudfront.net/20141020/47034972b1207c3982eed5f412f5322b.gif Results jmohn https://padlet.com/jmohn/osktwc4vclx3/wish/130936157
The results yielded that the solution with the highest carbon dioxide concentration produced the fastest rate of photosynthesis due to higher availability of carbon dioxide. This also meant it took the solution with the smallest amount of carbon dioxide the most amount of time to reach 50% floating.          ]]> 2016-10-15 20:40:23 UTC https://padlet.com/jmohn/osktwc4vclx3/wish/130936157 Conclusion jmohn https://padlet.com/jmohn/osktwc4vclx3/wish/130936158 The results of this experiment support the hypothesis that under appropriate photosynthetic conditions if the amount of carbon dioxide is raised, the rate of photosynthesis will increase. Sources of error could be miscalculation, counting leaf chads improperly or not correctly measuring baking soda. This experiment could be repeated with different types of leaves to see if it holds true.]]> 2016-10-15 20:40:23 UTC https://padlet.com/jmohn/osktwc4vclx3/wish/130936158 Procedure jmohn https://padlet.com/jmohn/osktwc4vclx3/wish/130936159  1. Cut out 40 leaf chads from same leaf. 
2. Mix 4 total different solutions containing 300 milliliters of  distilled water  and differing percent composition of baking soda or carbon dioxide source. Each should be 2%, 4%, 6% and 8% respectively. 2% will act as control.  Add 2-3 drops of detergent to each solution. 
3. Place 10 leaf chads in syringe and draw 5 cc of each solution into syringe. Push excess air out and create a vaccuum  to remove excess carbon dioxide.
4. Place the ten leaf chads from matching syringe concentration to the large container with solution. 
5. Put all solutions with leaf chads under light and calculate the time it takes for half of the leaf chads to rise.           ]]> 2016-10-15 20:40:23 UTC https://padlet.com/jmohn/osktwc4vclx3/wish/130936159 Research Question jmohn https://padlet.com/jmohn/osktwc4vclx3/wish/130936160 How does the concentration of carbon dioxide effect photosynthesis in spinach leaves?]]> 2016-10-15 20:40:23 UTC https://padlet.com/jmohn/osktwc4vclx3/wish/130936160 Hypothesis/Prediction jmohn https://padlet.com/jmohn/osktwc4vclx3/wish/130936161 Hypothesis: The higher concentration of carbon dioxide the spinach leaves are exposed to, the faster the rate of photosynthesis will be.

Prediction: If the leaf chads are kept in an environment higher in carbon dioxide concentration, then their rate of photosynthesis will increase.
