Earth Science Unit Study - Angle of Rest
Week 35: We tested several different materials to determine their natural angles of rest.
The question - What are the characteristics of materials which have a big angles of rest, or will stack into the steepest hill. Hills of materials such as corn, sand, gravel and rock, each have a unique steepness. Some materials will stack nicely into a very steep hill, where as others will slide down until nearly flat.

This was a fun project and a great one to do in conjunction with a science fair. For more Earth Science project ideas, be sure to visit our Science Page.
