Static Friction Prediction

In this activity (page 2 of PDF), learners will predict which objects have to overcome the most static friction to slide down a ramp. Learners then test their prediction as well as measure and calculate the ramp’s ratio of rise to run to quantify their results. Relates to the linked video, DragonflyTV GPS: Kinetic Sculpture Challenge.
