Science Fair Project Effective of caffeine on plants

Science Fair Project <Effective of caffeine on plant’s growth> Jenny Na, Naomi Lee, Sophia Han Ms. Rebecca Czekalski Korea International Christian School

Statement of the Problems - If we water a plant by caffeine mixed with water, will it grow faster?

Project Overview - We planted two tomato plants. We watered one plant by caffeine mixed with water and watered another plant with plain water. By this experiment, we found that the effect of caffeine on the plants.

Research • Caffeine effects people to tense • Stimulant is made of caffeine It temporarily affects the people’s body to be active • Increases the function

Variables - Controlled Variable : sunlight, soil, air, same amount of soil - Independent Variable : water mixed with caffeine - Dependent Variable : the height of each plant

Hypothesis - If I water a plant with water mixed with caffeine, then the plant with caffeine will grow faster.

Materials - 2 pots 2 tomato seeds 10 cc of caffeine each day 400 ml of water each day

Procedure - We planted tomato seeds and water them by 400 ml of water - We stared to give 10 cc of caffeine mixed with water to plant #1 and original water to plant #2 - One day we led both plants to water by rain

Data / Observation 25 20 15 Plant #1 Plant #2 Unit = CM 10 5 0 May 21 st May 25 th May 29 th

Conclusion - We discovered that caffeine didn’t had an effect on the plants

Future Research To improve our science fair project we need to measure the amount of caffeine and test it to find out that which amount of caffeine is fit to make the tomato plant to grow larger.
