Materials Engineering

Materials engineers are experts on materials and their properties.  They are at the forefront of matching materials with a specific purpose.  If there isn't a material fit for a purpose, they also help to design new materials with new properties.  Not only do materials engineers know about human-made materials, they must know about natural materials as well.

4.  Observing and Testing Wet Earth Materials!

2/13/2013

 
Picture

When students determined that the dry earth materials were not sticky, they figured out we better come up with a better solution for the mortar for our walls.  A mixture!

By mixing clay, soil, and sand with water, students quickly discovered that it changed the properties of the mixture.  Each mixture not only changed color but also its stickiness.  

Clay was by FAR the "best" choice for a mortar...students had a hard time getting their fingers unstuck.  "We NEED to use this for the mortar!" a first grader shouted.

    I love what I do.  No ifs, ands, or buts about it.
