Effect of caffeine on plant growth

Postby tanya26paul » Wed Nov 08, 2017 8:06 pm

My name is Tanya, and I am a 7th grade student. I am seeking assistance in a countywide science fair and it would be greatly appreciated if you could answer the following questions for me.

The experiment is on the effect of caffeine on plant growth.

1. Have studies regarding caffeine in agriculture been conducted before? If so, what was the outcome of these studies?

2. Does the type of plant influence the effect caffeine has on it?

3. Do you have any suggestions or recommendations regarding my experiment?

Thank you for taking the time for reading and responding to my questions.

Hi Tanya,

Finding the answers to your questions yourself on the web is really what you should be doing. Reading and researching online is something you need to become good at for success in all your school subjects.

I did a search for caffeine's affects on plants and found the following sites that have such information, but there are many, many more. Check out some of these and if you have specific questions we can help you understand.

There are a lot of google hits on the topic of caffeine and plant growth but be careful in what you read and accept as factual information. Try to stick to sites from known organizations and schools and articles published in peer-reviewed journals. While doing that does not guarantee that your information is accurate, it does increase the odds in your favor. Science is a self-correcting system. Theories and hypotheses are only as good as the data that backs them up and scientists do make mistakes. When better data is published then the story changes to hopefully be more true to life.
