This SciGirls video shows the girls collecting data on different household materials to see how much friction there is between them and a sheet of ice. Before building a prototype of a new product it is important to test your materials. In the process of creating non-slip boot covers, the girls need materials that will not slip on the ice. The collect data about the pounds of force it takes to move the materials across a sheet of ice to predict how the might behave when made into a boot cover.
