Introduction The purpose of this experiment was to find out if
we water a sunflower seed with vinegar is it going to grow the same
as if we water a plant with tap water. the control in this
experiment was -tap water The variable in this experiment was
vinegar
Slide 4
Materials Plastic cup super growing pellets Triple beam balance
scale Sunflower seeds 10% vinegar water Ruler Data sheet
Slide 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. We need to add more
to 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. 8. Each day, repeat steps 3 through 8.

Ask a QuestionAsk a Question The purpose of this experiment was
to find out if we watered a sunflower seed with vinegar if it was
going to grow the same as if we water one with tap water. My
question: Is the plant that we watered with vinegar going to grow
the same as the plant we watered with tap water
Slide 8
State Your HypothesisState Your Hypothesis If I plant a
sunflower seed I think the acid will delay the growth of the
sunflower.
Slide 9
Identify Control & VariableIdentify Control & Variable
The control was tap water. The variable was tap water with
vinegar.
Slide 10
Test Your HypothesisTest Your Hypothesis If I add vinegar water
to my sunflower seed, then its growth would be delayed. I think
this because acid can delay things so I thought it would of delayed
the growth of the sunflower.

Interpret Your DataInterpret Your Data The acid helped the
sunflower grow There were no negative affects. Our plant grew
AWESOME !!!!
Slide 13
State Your ConclusionState Your Conclusion The results of this
lab did not support the initial hypothesis because the plant did
grow just fine. I learned that if you water a sunflower with
vinegar it will grow. This experiment were The vinegar helped the
sun flower seed grow. This experiment could be extended in the
future by doing the same thing we did but this time water a
sunflower with tap water only.
