Period 7th

2. Introduction
The purpose of this experiment was to find out if your plant would grow.
The control in this experiment was tap water
The variable in this experiment was the vinegar water

3. Materials Plastic cup super growing pellets Triple beam balance scale
Sunflower seeds
Water or 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 …
My question: what did the vinegar water do to the seed?

7. State Your Hypothesis
If I plant a sunflower seed I think it will turn into a flower.

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

9. Test Your Hypothesis
If I add tap water to my sunflower seed, then it will turn into a flower because when you water the seed it will grow into a flower.

10. Collect & Record Your Data

day g 70.8g .10g
day g 86.7g 2.6g

11. Interpret Your Data
My plant did not grow because we used vinegar water so it died.

12. State Your Conclusion
It did not turn into a flower because it did not like that vinegar
water
