Figure 2. Have the holder of the protractor hold the protractor vertically with the origin (zero point) at the end of the cardboard sheet on the newspaper. Have the tilter SLOWLY lift the end of the cardboard in a smooth but continuous motion. The observer will note when particles first begin to slide off the pile and will observe and record this angle.
