1. Sunflowers and Acid Rain
Talent 21 Project

Period 3

2. Introduction
The purpose of this experiment was to find out what type of affect will vinegar water have on sunflowers. Plants need water and sun to grow.
The control in this experiment was tap water
The variable in this experiment was vinegar water

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

4. Methods Add 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. (Did you need to add more or less water? Did you need to rotate 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.

5. Scientific Method Ask a Question State Your Hypothesis
Identify Control & Variable
Test Your Hypothesis
Collect & Record Your Data
Interpret Your Data
State Your Conclusion

6. Ask a Question
The purpose of this experiment was to find out if sun flower seeds will grow when adding vinegar water.
My question: will the vinegar water effect the sun flower seeds growth?

7. State Your Hypothesis
If I plant a sunflower seed and vinegar water is added to it, it will grow.

8. Identify Control & Variable
The control is the tap water.
The variable is vinegar water.

9. Test Your Hypothesis
If I add vinegar water to my sunflower seed, then it will grow because plants need water for food.

10. Collect & Record Your Data

12. Interpret Your Data
The results showed that vinegar water made my plant grow.
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. No scientific errors occurred and affected the results.

13. State Your Conclusion
The results of this lab did support the initial hypothesis because the plant got the right amount of water and sunlight. Some things that were learned from this experiment were plants grow with the right stuff. This experiment could be extended in the future by using different seeds
