Let it Grow

ID # 160255

Problem / Question Data Data Analysis/Statistics

I am trying to test if there is a way to make plants grow faster. The results do not support my hypothesis; the plants with caffeine (200 or 400
mg) did not experience the most growth. In fact, the growth was no different
than the plants given no caffeine. There were no changes from the original plan
of my experiment; however, I did move my plants inside because of the cold
weather. This experiment can help those exploring new ways to improve plant
growth. Although my experiment was unsuccessful, future researchers can

Hypothesis
explore the addition of caffeine to plants in different mixtures and forms. More
experiments can be conducted on different types of plants and different types
of solutions with the goal of increasing plant growth.

If caffeine is added to bean plants in varied amounts, then the plants

given the highest dose of caffeine will have the tallest growth.
Conclusion
This project intended to test the effects of (200 mg and 400 mg) caffeine on plant

Materials & Methods Photos growth. I hypothesized that if caffeine was added to bean plants in varied amounts,
then the plants given the highest dose of caffeine (400 mg) would have the tallest
growth.
I began by planting 45 bean seeds in 15 pots (3 seeds / pot). I divided the pots into
three groups of 5 pots each. I added 200 mg caffeine to the soil in the first 5 pots, 400
mg caffeine to the soil in the next 5 pots, and 0 mg caffeine to the soil in the last 5 pots.
- Plant 3 bean seeds in each of the 15 pots. I labeled the pots in each group 1 to 5. In Pots #1, the plants with 0 mg caffeine and
- Add 200 mg of caffeine to the soil of 5 plants. 400 mg caffeine both has the tallest plants, with a height of 16 cm. In Pots #2, the
- Add 400 mg of caffeine to the soil of 5 plants. plants with 0 mg caffeine grew the tallest, with a height of 15.5 cm. In Pots #3, the
plants with 200 mg caffeine grew the tallest, with a height of 17 cm. In Pots #4, the
- Water all plants with the same amount of water regularly.
plants with 0 mg caffeine grew the tallest, with a height of 13.5 cm. In Pots #5, the
- Measure the height of each plant daily. plants with 200 mg caffeine grew the tallest, with a height of 17 cm. In this experiment,
- After two weeks, compile the data. caffeine did not have much of an effect on plant height.
