  1. Sunflowers and Acid Rain . Talent 21 Project By : Aliyah DeShields Date : 1/2/12 Period: 7

  2. Introduction • It took about Three days for my plant to grow I think the vinegar helped the plant more then the tap water. I think the people that used the tap water for their plant didn’t grow as fats as the people that used vinegar , I was one of the people that used vinegar and I think it worked at but it seem to me that the people that used tap water struggled with there plant. • The control in this experiment was Tap Water • The variable in this experiment was Vinegar

  3. Materials • Plastic cup • super growing pellets • Triple beam balance scale • Sunflower seeds • Water or 10% vinegar water • Ruler • Data sheet

  4. Methods • Add super growing pellets to cup. • Add 3 tablespoons of water to expand. • Plant 3 seeds per cup. • Weigh cup on triple beam balance. Record weight. • Add tap water or vinegar water to cup. Weigh again and record data. • Cup will be placed under grow light. • 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?) • 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. • Each day , repeat steps 3 through 8.

  5. Scientific Method • Ask a Question • State Your Hypothesis • Identify Control & Variable • Test Your Hypothesis • Collect & Record Your Data • Interpret Your Data • State Your Conclusion

  6. Ask a Question • My question: How did the plants grow so fast and a certain amount of days . I think the vinegar helped the plant because it was healthy and strong.

  7. State Your Hypothesis • I predict that my plant will not survive because its too late , and my plant was growing good and then it died . I would of loved to see my plant grow but I think I should of took more care of it.

  8. Identify Control & Variable • The control is tap water . • The variable is vinegar water .

  9. Test Your Hypothesis • If I add Vinegar water to my sunflower seed, then it will grow strong and healthy because the vinegar water is more better then the tap water . I think the tap water wasn’t so good because people that used it were mad because there plant wasn’t growing

  10. Collect & Record Your Data

  11. Interpret Your Data • The plant grew and I had no problems everything went just right and perfect.

  12. State Your Conclusion • The results of this lab didsupport the initial hypothesis the vinegar was a good choice for the flower
