The studentsthought that the grass helped hold the soil in place on the students predicted that more soil would wash down a slopewithout grass than a slope covered with grass.

7 To find out if theywere correct, the students conducted an experiment with threeidentical rectangular pans of soil. In pan 1, they planted grassseed and allowed it to grow to several centimeters tall. The stu-dents filled pan 2 with only soil. Then they took pan 1 and pan 2,and propped up at one end of each pan 15 cm high to create aslope. Pan 3, also filled with only soil, was propped up at one end5 cm at one end to create a slope. Students poured equal amountsof water on the raised end of each pan and the students recordedtheir hypothesis did the students test in their experiment?

8 Prediction did the students use to test their hypothesis? steps in the experimental method are missing from the descriptionabove? the students conduct a good experiment?
