TESTABLE QUESTION: What are the effects of different amounts of aspirin on sunflower germination?
BACKGROUND: Aspirin is probably the most well-known pain killer. Aspirin is a salicylate, a bitter compound present in certain plants, and a nonsteroidal anti-inflammatory drug. Aspirin can treat headaches, pain, fever, and inflammation. It can also decrease the risk of a heart attack, strokes, and chest pain. It works by blocking a certain natural substance in the body to reduce pain. Esther Inglis-Arkell says “It was derived from willow and birch bark, and works by blocking a certain enzyme. Cyclooxygenase-2 is basically an alarm bell, ordering out the troops. It manufactures a chemical called prostaglandin, …show more content…
Three flower pots were labeled “Two Aspirin”, “One Aspirin” and “No Aspirin”.
2. Dissolve two tablets of aspirin in one half cup of boiling water.
3. Dissolve one tablet of aspirin in one half cup of boiling water.
4. Steps 2 and 3 are repeated each day for eight days.
5. While the aspirin water is cooling, two cups of soil are added to each flower pot.
6. Two seeds are also added to the pots are buried 50 mm in the soil.
7. Every day the aspirin water is added (one half cup) to the plant with the correct amount of aspirin while normal water is added to the “No Aspirin” pot.
8. Record the growth of the seeds every day with a ruler and take notes.

The average sunflower seed germinates in seven to ten days. The seeds with the most aspirin grew the fastest at germinating, 19 mm by six days and the seeds without aspirin was at 0 mm by day six. This supports the hypothesis because the sunflower seeds with aspirin grew more quickly than the seeds without the
