The experiment is about whether the concentration of sodiumbicarbonate will have an effect or not on the rate ofphotosynthesis in spinach by recording the time taken by the leafdisks to float in the sodium bicarbonate solution with differentconcentrations (0.7% and 1.5%) as treatment groups and thedistilled water as the control group.
Is it possible for leaf disks to float in thecontrol group(Distilled water)?
Why do you think the leaf disks floated at different times inyour trial run?
What are the potential sources of error? How will youtroubleshoot these when running your experiment?
On what basis will you determine the number of replicates to beused?
