4 A lab team conducted an investigation
to determine
which type of soil best retained water. They set up
four 100 ml graduated cylinders and placed a funnel and
coffee filter in each. They put the same volume of four
different types of soil in each filter. Then, they poured 50
ml of water into each filter. Finally, they measured the
amount of water in the graduated cylinders that had
filtered through the soil. Their data table is below.
