Connecting Friction to Engineering

During a learning unit on moving objects, fourth graders at Dinwiddie Elementary school got to put science to the test while experimenting with friction. Students where challenged to work in small groups to study friction on a surface (i.e. sandpaper, wax paper) with different types of shoes to help determine the best shoe sole for certain situations. First, students collected three shoes and used filled water bottles to adjust the weight of the shoes to be equivalent before testing them on a surface. Next, students used probeware to measure the force it took to pull each shoe across the surface.
