4. Introduction TThe purpose of this experiment was to find out was how plants grow and how the acid rain help the plant grow and how the regular water makes the plant grows.

5. Methods 1. Add super growing pellets to cup. 2. Add 3 tablespoons of water to expand. 3. Plant 3 seeds per cup. 4. Weigh cup on triple beam balance. Record weight. 5. Add tap water or vinegar water to cup. Weigh again and record data. 6. Cup will be placed under grow light. 7. Observe the container daily and note any indications of growth(by observations and measurement) and compare to other containers in the experiment. While observing indicate any special care given to the plant. (Did you need to add more or less water? Did you need to rotate the plant?) 8. Record observations, measurements, and comments in the plant growth diary. Once the plant begins to grow, you will need to draw a detailed picture of the plant including the appearance of leaves and stems. 9. Each day, repeat steps 3 through 8.

7. Ask a Question TThe purpose of this experiment was to find out … (Include background information about requirements for plant growth and plant needs- your textbook would be a good place to begin gathering background information. Include information about the plant or the variable you used to help make your plant go and its importance in this experiment. My question: How can plants grow

8. State Your Hypothesis IIf I plant a sunflower seed I think that it will grow because we have acid rain it will get a little bit big

9. Identify Control & Variable CControl – stays the same VVariable- changes

10. Test Your Hypothesis IIf I add 3 cup water to my sunflower seed, then it grow up a lot with sun light because they need water and sun light to stay alive

12. Interpret Your Data TThis is where you put your analysis. The results showed that ( Describe general trends from your data) AAs part of this experiment there may have been variables or scientific errors that could have affected the growth of the plants and the outcome of this experiment. The variables affecting the results may have been ( Describe any variables in your particular experiment.) Scientific errors that could have occurred and affected the results include ( describe – for example used the wrong type of water )

13. State Your Conclusion TThe results of this lab (did/did not ) support the initial hypothesis ( explain why you think this was the outcome.) Some things that were learned from this experiment were (identify what you learned without using first person) This experiment could be extended in the future by ( identify an investigation that would be a natural next step based on your results.) AAdd Graphic
