3. Problem Statement What are the components of a problem statement? How do the independent and dependent variables fit into this statement? What are the components of a problem statement? How do the independent and dependent variables fit into this statement?

4. Background Research Why do we need background information?

5. Hypothesis If, then, because Third person Which variables fill in the blanks? If more fertilizer is added, then the plant will grow taller because it has extra nutrients.

6. Experiment What are the parts of this step? Materials, procedure What are the parts of this step? Materials, procedure

7. Data Analysis Calculate the average: Trial 1: 11.3 cm Trial 2: 9.6 cm Trial 3: 8.9 cm Average: 9.93 cm Calculate the average: Trial 1: 11.3 cm Trial 2: 9.6 cm Trial 3: 8.9 cm Average: 9.93 cm

8. Conclusion The hypothesis, having plants exposed to light for longer periods of time will result in more plant growth, is accepted. In this test the plants exposed to light for 16 hours were 27 cm on average after three weeks as opposed to the plants given 10 hours of light that were only 15 cm on average. This procedure is weak in the fact that there were only 6 plants per group and it would be better to have measurements over a period of time. In the future I would experiment on the effect that long periods of light has on different varieties of plants.

9. Communicate the results It is important to be able to present your project and be able to explain all of the steps you followed to get to your results.
