BEST COLLABORATED DESIGN FLOWERS

Edit 0 5 …
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

Control Group-
The flowers in regular water

Experimental Group-
The flowers soaking in water contaning asprin.

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
