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: The flowers kept in water with asprin will last longer than the flowers in plain water. 2. Explain how to set up the experiment: You start by getting a pot of water, one with asprin in it and one without asprin. Then place 10 flowers in each vase. You should keep copying down the results until one of the flowers starts to wilt.
Brainstorm a list ofall the variables that must be kept constant during the experiment:
make sure that the water was the same temperature
the vase was the same size
the stems were cut the same length
it was the same type of blue flower
make each vase of flowers had the same amount of sunlight
make sure each vase had the same amount of water.
Independent variable: Asprin
Dependent variable: Which stay fresh the longest.
Identify the control group: Water without asprin
Identify the experimental group(s): Water with asprin
3. Provide enough details for someone else to set up your experiment: You start by getting a pot of water, one with asprin in it and one without asprin. Then place 10 flowers in each vase. You should keep copying down the results by taking pictures so you have enough results to conclude the experiment.
