2 Sunflowers and Acid Rain Talent Project Talent 21 Project By: April Ernst Date: Date: May 4,2012 Period Period : 4 th

3 Introduction  The purpose of this experiment was to find out … if we water a sunflower seed with vinegar is it going to grow the same as if we water a plant with tap water.  the control in this experiment was -tap water  The variable in this experiment was – vinegar

4 Materials  Plastic cup  super growing pellets  Triple beam balance scale  Sunflower seeds  10% vinegar water  Ruler  Data sheet

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. We need to add more to 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. 8. Each day, repeat steps 3 through 8.

6 Scientific MethodScientific Method  Ask a Question  State Your Hypothesis  Identify Control & Variable  Test Your Hypothesis  Collect & Record Your Data  Interpret Your Data  State Your Conclusion

7 Ask a QuestionAsk a Question  The purpose of this experiment was to find out … if we watered a sunflower seed with vinegar if it was going to grow the same as if we water one with tap water.  My question: Is the plant that we watered with vinegar going to grow the same as the plant we watered with tap water

8 State Your HypothesisState Your Hypothesis  If I plant a sunflower seed I think the acid will delay the growth of the sunflower.

9 Identify Control & VariableIdentify Control & Variable  The control was tap water. The variable was tap water with vinegar.

10 Test Your HypothesisTest Your Hypothesis  If I add vinegar water to my sunflower seed, then its growth would be delayed.  I think this because acid can delay things so I thought it would of delayed the growth of the sunflower.

11 Collect & Record Your DataCollect & Record Your Data  DayDry Wt.Wet Wt.Difference  16570.74.2  250.250.53  340.750.410.3  440.350.510.2  546.850.24.2  63030.99  720.930.710.2

12 Interpret Your DataInterpret Your Data  The acid helped the sunflower grow  There were no negative affects. Our plant grew AWESOME !!!!

13 State Your ConclusionState Your Conclusion  The results of this lab did not support the initial hypothesis because the plant did grow just fine. I learned that if you water a sunflower with vinegar it will grow. This experiment were The vinegar helped the sun flower seed grow. This experiment could be extended in the future by doing the same thing we did but this time water a sunflower with tap water only.

14 THE END!!!! THE END!!!!
