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 exper-iment, 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 caf-feine will grow faster.

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

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

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 caf-feine and test it to find out that which amount of caffeine is fit to make the tomato plant to grow larger.
