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 ofall 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
Do cut flowers last longer if kept in water that contains aspirin?
Hypothesis- They will not last any longer if kept in water that contains aspirin
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- Cut flowers Dependent Variable- Flowers in regular water
Control Group: The group with the flower that is put in regular water Experimental Group:The Group with the cut flowers put in water containing aspirin
Steps to conduct experiment(procedure): 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
