Period 8

Introduction The purpose of this experiment was to find

out how long it takes a plant was to see how long it takes a plant to grow. Not all will grow at the same time some will grow faster then others so it is just a matter of time. To find out was better vinegar or water.

The control in this experiment was water

The variable in this experiment was vinegar

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 what kind of water will

make the plant to grow faster vinegar water or tap water. We look at the

growth of each plant and the water we used to water them.

State Your Hypothesis If I plant a sunflower seed and water

it with tap water then you will get a plant. I think that when I water it my plant will not grow the first couple days because it needs a couple days to take its time and grow on its own.

Identify Control & Variable

Control used tap water to water the plant every day.

And the variable had to use vinegar water to water the plant.

Test Your Hypothesis

If I add water to my sunflower seed, then it will grow because a plant needs water to grow. plants also need sunlight to grow.

Interpret Your Data

In my line graph I have data about how much my plant grew over a

week and the height how much it weighed and how much we water it that day. It goes up the more bigger the number is and goes down each

time the number goes down.

State Your Conclusion

In my power point talk about how much my plant grew, weighed, and the height. What water we used for the plant to grow each day we used tap water for the control and vinegar for the variable.
