Investigating Variables Affecting Photosynthetic Rates in Plants
1. Variable: sodium bicarbonate concentration2. Type of leaf: fresh organic spinach leaves3. Total Time: 5 minutes, checked every 1 minute
4. 8ml of 10 leaf disks in a .2% sodium bicarbonate solution
5. Conclusion:
Results were inconclusive. The only group that leaf disks sank to the bottom was in the control group.
Sodium bicarbonate concentrationControl Group: solution with a drop of soap = 6/10 floatGroup 1: 15g in 400ml = no change 10/10 floatGroup 2: 25g in 400ml = no change 10/10 floatGroup 3: 35g in 400ml = no change 10/10 float
Light intensityControl Group: solution with a drop of soap = 6/10 floatGroup 1: light on vs off: = no change 10/10 floatGroup 2: light on vs off: = no change 10/10 floatGroup 3: light on vs off: = no change 10/10 float
