Do cut flowers last longer if kept in water that contains aspirin?


 * INCLUDE ALL OF THE FOLLOWING WITH YOUR EXPERIMENTAL DESIGN: **
 * [remember it must be a controlled experiment] **
 * 1. A hypothesis **
 * 2. Explain how to set up the experiment: **
 * ** brainstorm a list of all the variables that must be kept constant during the experiment **
 * ** include identification of the independent variable **
 * ** the dependent variable **
 * ** identify the control group **
 * ** identify the experimental group(s) **
 * 3. Provide enough details for someone else to set up your experiment **


 * Hypothesis- ** **Flowers in water containing aspirin will not last as long as a flower in regular water**.


 * Variables- **


 * 1. Species of flower **


 * 2. **** Water **


 * 3. Age of flower **


 * 4. Temp. of water **


 * 5. Amount of aspirin **


 * 6. Age of aspirin **


 * 7. Type of water **


 * 8. Age of water **


 * 9. Brand of aspirin **


 * 10. Size of container **


 * 11. Material of container **


 * 12. Age of flower **


 * 13. Amounts of sunlight each flower is exposed to **


 * 14. How and when the flowers were cut **


 * Independent Variable- **
 * The aspirin that is in the water. **

Dependent Variable-
The water with asprin

The flowers in regular water
 * Control Group- **

The flowers soaking in water contaning asprin.
 * Experimental Group- **


 * Conclusion- **
 * 1. Collect flowers for experiment **
 * 2. Place the flowers in two seperate containers **
 * 3. Place one flower in the water containing aspirin and the other in regular water **
 * 4. Allow the flowers enough time to tell whether one or the other lasted longer **
 * 5. Evaluate between the two flowers to see which lasted longer **
