Acid Rain

Sunflowers and Acid RainTalent 21 ProjectBy: April ErnstDate: May 4,2012Period : 4th

1IntroductionThe 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

2Materials Plastic cupsuper growing pelletsTriple beam balance scaleSunflower seeds 10% vinegar waterRulerData sheet3MethodsAdd 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. 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.Each day , repeat steps 3 through 8.4Scientific MethodAsk a QuestionState Your HypothesisIdentify Control & VariableTest Your HypothesisCollect & Record Your DataInterpret Your DataState Your Conclusion

5Ask a QuestionThe 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 water6State Your HypothesisIf I plant a sunflower seed I think the acid will delay the growth of the sunflower. 7Identify Control & VariableThe control was tap water. The variable was tap water with vinegar .8Test Your HypothesisIf 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.9Collect & Record Your DataDayDry Wt.Wet Wt.Difference16570.74.2250.250.53340.750.410.3440.350.510.2546.850.24.263030.99720.930.710.2

10Interpret Your Data The acid helped the sunflower grow There were no negative affects. Our plant grew AWESOME!!!!11State Your ConclusionThe 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.
