3. Introduction  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 ___water_________  The variable in this experiment was seeds

4. Materials  Materials  Plastic cup  super growing pellets  Triple beam balance scale  Sunflower seeds  Water or 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. (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.

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 how well my plant grows with acid rain and regular water as my variable  My question: ___________________________

8. State Your HypothesisState Your Hypothesis  If I plant a sunflower seed it will grow every two days

9. Identify Control & VariableIdentify Control & Variable  My control is water it helps the variable proceed to help the project grow  My control is seeds it’s the plant its self its the whole project the control will sprout so I can find out if my hypothesis was correct or not

10. Test Your HypothesisTest Your Hypothesis  If I add of water to my sunflower seed, then it __will sprout because I watered it enough to grow_______________________________________ ________________________________________.

12. Interpret Your DataInterpret Your Data  This is where you put your analysis. The results showed that every day I watered it and it never grew.  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 water, plant holder or type of water Scientific errors that could have occurred and affected the results include I accidently used acid rain instead of regular.

13. State Your ConclusionState Your Conclusion  The results of this lab did not support the initial hypothesis I think this was the outcome because I didn’t water it the way I was supposed to water it Some things that were learned from this experiment were how to water a sunfloweer seed This experiment could be extended in the future by different plants being watered by different kinds of liquid  Add Graphic
