Period :4th

Introduction

The purpose of this experiment was to find out … If Vinegar water could work with a plant

the control in this experiment was Tap water

The variable in this experiment was Vinegar water .

Materials

Plastic cup

super growing pellets

Triple beam balance scale

Sunflower seeds

Water or 10% vinegar 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 … (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: How can a plant grow from vinegar water.

State Your Hypothesis

If I plant a sunflower seed with vinegar water I think the plant will not go to me I think it would kill the sunflower seed.

Identify Control & Variable

Vinegar water IS THE VARIABLE

TAP WATER IS THE CONTROL

Test Your Hypothesis

If I add Vinegar water to my sunflower seed, then it Will die because the chemicals will go in the seed and the seed will die .

Collect & Record Your Data

Interpret Your Data

To show how the plant life.

State Your Conclusion

My hypothesis is not supported . our plant did not die it was growing with vinegar water
