In this silent video I show how a group of Ag and math students estimate slope in order to calculate how erodible the newly planted field will be. I just wanted the video up fast. I will spend some more time later refining it and adding some other explanations.

A major question I had as a math teacher, after hearing this is how the Ag class estimates slope at a range management competition.

How is it possible to use the hypotenuse to calculate a fairly accurate estimate?
