1 Sunflowers and Acid Rain Talent 21 Project By ___________ Date _________ Period ________

2 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 ____________  The variable in this experiment was ___________

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

4 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 Ask a QuestionAsk a Question  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.  My question: ___________________________

7 State Your HypothesisState Your Hypothesis  If I plant a sunflower seed

8 Identify Control & VariableIdentify Control & Variable

9 Test Your HypothesisTest Your Hypothesis  If I add ___________water to my sunflower seed, then it ____________________________________ because____________________________________ ___________________________________________.

10 Collect & Record Your DataCollect & Record Your Data  (Insert your data here, including any pictures, drawing, graphs)

11 Interpret Your DataInterpret Your Data  This is where you put your analysis. The results showed that (Describe general trends from your data)  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 (Describe any variables in your particular experiment.) Scientific errors that could have occurred and affected the results include (describe – for example used the wrong type of water )

12 State Your ConclusionState Your Conclusion  The results of this lab (did/did not) support the initial hypothesis (explain why you think this was the outcome.) Some things that were learned from this experiment were (identify what you learned without using first person) This experiment could be extended in the future by (identify an investigation that would be a natural next step based on your results.)  Add Graphic
