2.  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. Include background information which you might have used to develop your hypothesis.)  The control in this experiment was ____________  The variable in this experiment was ___________

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

4. 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.

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

7.  If I plant a sunflower seed with the vinegar water it would not grow.

8. The control in this experiment is the tap water and the variable in this experiment is the 10% vinegar water.

9.  If I add tap water to my sunflower seed, then it will grow because sun and water are needed for plants to grow.

11.  The results showed no growth.  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 the vinegar may have killed it. Scientific errors that could have occurred and affected the results include a lack of sunlight.

12.  The results of this lab did support the initial hypothesis because the vinegar water killed the seed. Some things that were learned from this experiment were that vinegar kills plant seeds. This experiment could be extended in the future by using spring water or plant food.
