Serc: Angle of Repose
In this activity, young scholars measure the maximum slope at which grains are stable (the angle of repose). They explore how different properties of the sediment influence slope stability and lead to different slope failures (mass...

Teach Engineering: Forces and Graphing
This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students...
