TRANSCRIPT
Introduction
The purpose of this experiment was to find out if acid rain affects plants
The control in this experiment was tap water
The variable in this experiment was 10% vinegar water
Materials
Materials
Plastic cup
super growing pellets
Triple beam balance scale
Sunflower seeds
Water
Ruler
Data sheet
Methods1. 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.

Ask a Question
The purpose of this experiment was to find out if acid rain affects a plant
My question: does acid rain affect sunflowers
State Your Hypothesis
If I plant a sunflower seed and give it water it will grow into a sun flower like regular but if you give it vinegar water you will kill your plant.
Test Your Hypothesis
I added tap water to my sunflower seed, then it grew regularly because the seeds had regular water. But the vinegar water killed almost all the plants

Interpret Your Data
This is where you put your analysis. The results showed that the trend was a pattern it went up and then down
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 the vinegar Scientific errors that could have occurred and affected the results include pouring regular water on the experimental plants
State Your Conclusion
The results of this lab did support the initial hypothesis because it grew into a sun flower. Some things that were learned from this experiment were that no matter what kind of water you use you will always have a sunflower. This experiment could be extended in the future by actually putting acid rain in a room with a plant.
