This resource appears to be designed to build towards this science and engineering practice, though the resource developer has not explicitly stated so.
Comments about Including the Science and Engineering Practice
Students could extend this hands-on activity to include measurements. They could increase the elevation of their soil mountain, volume of water at water erosion station, amount of "wind" created by the fan, and use a sheet of ice in the stream table to increase amount of ice at glacier station. They could record observational differences and measure amounts of sediment . ELL students could illustrate variability in chart form and/or collect sediment, weight sample, and graph weight results.
