  1. Sunflowers and Acid Rain Talent 21 Project By: Samantha Osinski Date: May 4, 2012 Period: 8thPeriod

  2. Materials • Plastic cups • Super growing pellets • Triple beam balance scale • Sunflower seeds • Water or 10% vinegar water • Ruler • Data sheet

  3. 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.

  4. Introduction • The purpose of this experiment was to find out which type of liquid made the plants grow faster, either tap water or vinegar. Your plant needs water, carbon dioxide, sunlight, and chlorophyll. • The control in this experiment was the tap water. • The variable in this experiment was the vinegar.

  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 • The purpose of this experiment was to find out which type of liquid either vinegar, or tap water would make the plant grow faster. • My question: What type of liquid makes the plant grow faster, either vinegar or water?

  7. State Your Hypothesis • If I plant a sunflower seed with vinegar I think it won’t grow as fast as it will if I planted it with water.

  8. Identify Control & Variable • The variable of this experiment was vinegar water and the control of this experiment was water.

  9. Test Your Hypothesis • If I add tap water to my sunflower seed, then it won’t grow because we didn’t use enough water.

  10. Collect & Record Your Data

  11. Interpret Your Data Our plant did not grow at all. I think It didn’t grow because we didn’t water it enough.

  12. State Your Conclusion • The results of this lab did support the initial hypothesis. We didn’t use enough water. Some things that were learned from this experiment were is that if you don’t water your plant enough and give it sunlight it won’t grow. This experiment could be extended in the future by adding more time different plants or use all ready grown plants.
