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: Cut flowers kept in plain water wont last as long as cut flowers kept in aspirin.
2. Explain how to set up the experiment: You set up the experiment by getting 4 vases, and 100 of the same flowers. 2 vases with plain water, and 2 vases with the same amount of aspirin in them. Then you make sure the appropriate variables are constant then you should keep recording down the results each day.
brainstorm a list ofall the variables that must be kept constant during the experiment: amount of water, temperature of water, amount of sunlight, amount of aspirin in the two vases, same length of flower, same size flower, same type of flower, same color flower, same size vase, same quality of flower, same kind of aspirin, same location of flower, same temperature of place, where you get the water, the size of aspirin, and what is in the aspirin.
include identification of the independent variable- the water with aspirin added.
the dependent variable- which flower lives the longest.
identify the control group- The vases with no aspirin added.
identify the experimental group(s)- The vases with aspirin added to the water.
3. Provide enough details for someone else to set up your experiment: First get 4 vases that are the same size, then poor the same amount of water into each vase. Next you take the 100 flowers that are the same type and size and from the same place, and divide them into 4 groups. put 25 of them in a vase with no aspirin, then put another 25 in a vase with no aspirin. Next put 25 in a vase with aspirin added, then put the last 25 in a vase with aspirin added. make sure the groups of flowers are sitting in the same amount of sunlight at the same temperature. Also make sure that the two vases with aspirin have the same amount of aspirin. Therefor if you put 2 aspirin in one of the vases you must put 2 aspirin in the other vase. You also should make sure the aspirin is the exact same size and shape and that is has all the same ingredients in it. you must make sure the plants are all exactly the same. Then after you make sure all the appropriate variables are constant, you record your results and see which group of plants grow the longest.
