Ask a Question
During this lab we…Watered the sunflowers with 20mL of unpolluted water , and we weighed them before we watered the flowers and after we watered the flowers.
What we wanted to find out… was what will happen to the plant if it was watered with unpolluted water?
Control vs. Variable State your hypothesis
In this slide you are to write whether your group was a control group or an experimental group. My group was the control group.
State your hypothesis I hypothesize…that my groups flower will grow unaffected by the unpolluted water.

Data Interpretation
What happened during your experiment? My flower grew !
› Think about: What could have affected your data . What
could have affected my data was polluted water because if my flower was polluted it wouldn’t have grown . Also it would’ve been more heavier because of the polluted water.
Explain your graph-Give a three to five sentence explanation of your data.
What happened in my graph was when the flower was wet it was heavier than when it was dry . Also it was a small difference.
State your Conclusion My hypothesis that stated…was
(correct/incorrect). Why do you think this happened?
What was something you learned from this experiment?
That if you water a plant with polluted water it will not grow.
How would you alter this experiment for future use?
I would put a stick to give support to my flower so that it would stay up straight.
