Gray Trash Cans Research
In our experiment, the control group would be the people using the gray trash cans. A control group is the group in an experiment where the independent variable being tested is not applied so that it may serve as a standard for comparison against the experimental group where the independent variable is applied. In our experiment, the independent variable are the colored trash cans. The people using the gray trash cans are the control group because nothing is changing when using the normal trash cans. Our group is going to experiment to see if the colored trash cans change the amount of litter around the forum of our school. One constant in our experiment would be the location of where the experiment takes place. A constant is a variable

The gray trash cans cannot change because we are experimenting to see if brighter trash cans collect more trash than the gray ones. If we were to change the gray trash cans, our group would not be able to compare the amount of trash in the brighter trash cans to anything. Therefore there would no longer be an experiment. One other constant is the color of the can. Some colors attract the human eye more than others. If one crash can is brighter than the other it will attract more people therefore more trash. The colors that are brighter to the human eye are red, blue,green, and yellow. Those colors are brighter to the human eye than other colors. Another constant is the time the trash cans are out. If we don't have the trashcans out at lunch or break the trashcans won't have any trash in the trash cans. This means that the experiment won't get done. leaving us with no data to use. The trash that is in the trash cans determines the outcome of the experiment. In our experiment another constant is the number of days the trashcans are out. You can get a different outcome of the amount of trash each day the trashcan is out. If we were to put the trash cans out for a different amount of days we would get a different outcome. The number of days the trashcans are left out can determan the outcome of the
