 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: tap water.  The variable in this experiment was: acid water

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

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.

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

 The purpose of this experiment was to find out … if the tap water was better than the acid or vinegar water.  My question: which one is better the tap water or the vinegar water?

 If I plant a sunflower seed it will be able to maybe grow

 The control is tap water  then it is vinegar water

 If I add tap water to my sunflower seed, then it maybe grow because it might grow because and also when I wet it sometimes grows together.

 DateDry Wt.Wet Wt.Difference  day  day  day  day  day  day

 This is where you put your analysis. The results showed that the tap water really did not help my plant.  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 using to much water and we probably had have drowned the plant.

 The results of this lab did not support the initial hypothesis I think that because when I watered it every day it died till this day stand it did not grow. Some things that were learned from this experiment were that you should not use so much water and because it wasn’t that much water. This experiment could be extended in the future by making sure that it grows.
