Measuring Slope Percentages in Outdoor Classroom


While spending time in the outdoor classroom, sixth graders have measured slopes in each direction from the wetland area. They did this to determine where the most soil erosion is occurring.  Using the mathematical formula   rise ÷ run x100 = % slope, students were able to determine that the slopes with a higher percentage were the slopes on the west side of the wetland where the water runs into the area.  After verifying findings by experimenting with sand and water, students decided that the water enters the west side of the area faster and this causes a greater amount of soil erosion which leads to steeper slopes.
