Dieffenbachia plants usually grow well without fertilizer. A student wanted to see if adding
liquid fertilizer would make a difference in the growth of the plant. Three plants were placed
in the same type of pot with the same type of soil. Two plants received fertilizer and one
plant did not. All plants received the same amount of light and water during the experiment.
She watched the plants grow over a period of 30 days, only adding the same amount of
water to each plant on a weekly basis. Look at the table below and answer the questions
which follow concerning the student's experiment.
1. From the experiment above, what was the independent variable? fertilizer
2. From the experiment above, what was the dependent variable? growth
3. What conclusions can be drawn from this data? type of pot
and soil
4. What further experiments can be developed using this data as a guide?
5. Graph the data.
