Getting rid of plant's headaches.

Aspirin on plants.

Purpose Statement:

The purpose of this experiment is to see if aspirin will help plants grow. I am interested in this experiment because I want to see if there is a way to grow plants faster and/or healthier then plants with water. Also this could help farmers with their crops to grow faster.


The compound that makes up aspirin was first derived, salicylic acid, was found in the bark of a willow tree in 1763 by Reverend Edmund Stone of Chipping. The bark from the willow tree contains high levels of slicing, the glucose of salicylic acid. This was used in a different form all the way back in ancient Greece using willow leaves for the same purpose, to reduce fever and relieve the aches of a variety of illnesses.

The world record for the fastest growing plant belongs to certain species of the 45 genera of bamboo, which have been found to grow at up to 35 in. per day. According to the RHS Dictionary of Gardening, there are approximately 1,000 species of bamboos. The tallest recorded in the tropics was reportedly 130 ft, in Europe and the USA 65-98 ft. has been the tallest.


My hypothesis is the aspirin will kill the plant. I base my hypothesis on that because aspirin is a drug, it will probably harm the plant.



3 plants seeds (at least)

sun light


place to plant plants

IV=aspirin & water

DV=3 plant seeds

C=sun light,place to plant


  1. Get 3 plants that are the same.

2. Get at least 30 aspirin tablets and water.

3. Plant the plants in a pot or cup of some sorts.

4. Water 1 of them with just water.

5. Water another 1 with 2 CRUSHED aspirin tablets mixed with water.

6. Water last 1 with 4 CRUSHED aspirin tablets mixed with water.

7. Do step 4,5 and 6 every day.

8. Check your plants daily and record when they sprout.

Observations Log/Data:

Once I started watering the plants, it was very easy to keep track of them. The one with just water seemed to be doing the best. And it was. The other two plants with aspirin were not looking so good. They seemed way more dry then the other one. They had really dry soil while the one with water had rich and wet soil. The water plant sprouted in just four days. The four aspirin plant and the two were not sprouted and there were no signs of them to. After three weeks, they still didn’t sprout and there was a little bit of mold in the two aspirin and the four had a lot of mold in it. They died while the water one was healthy and still is.


The original purpose of this experiment was to see if aspirin will help plants grow.

The results of this experiment show that the water plant was the only one that sprouted.

My hypothesis was the aspirin would kill the plants. The results indicate that this hypothesis should be considered correct. Based on the results of this experiment I would not recommend to feed plants aspirin. If I were to conduct this science fair project again, I would use ibuprofen instead of aspirin.


I did this with myself and Janis, she got the aspirin, and the help of my Mom, that helped me watch the plants and water them.
