ou are interested in determining the amount of fertilizer your lavender plants need to increase their growth. You get 5 pots of plain soil. You transplant one lavender plant into each pot and measure the height of the plant. You label each pot with letters A-E. A does not get any fertilizer, pot B gets 2mg of fertilizer, pot B gets 4 mg of fertilizer, pot C gets 6 mg of fertilizer, pot D gets 8 mg of fertilizer, and pot E gets 10 mg of fertilizer. For one month you water the plants the same amount and each plant receives the same amount of light. After one month you measure the plants again. The results of the experiment are below. A. Write a testable hypothesis for this experiment. B. Write a prediction based on your hypothesis. C. What is the dependent variable? D. What is the independent variable? E. Do the results support or refute your hypothesis? Results Pot Initial Measurement (cm) Final Measurement (cm) A 5.2 7.2 B 5.1 8.4 C 5.3 10.9 D 5.2 15.3 E 5.3 5.8
