From urban centers to remote corners of Earth, the depths of the oceans to space, humanity has always sought to transcend barriers, overcome challenges, and create opportunities that improve life in our part of the universe. In the last century alone, many great engineering innovations have became so commonplace that we now take them mostly for granted. Technology allows an abundant supply of food and safe drinking water for much of the world. We rely on electricity for many of our daily activities. We can travel the globe with relative ease, and bring goods and services wherever they are needed. Growing computer and communications technologies are opening up vast stores of knowledge and entertainment. As remarkable as these engineering achievements are, certainly just as many more great challenges and opportunities remain to be realized. While some seem clear, many others are indistinct and many more surely lie beyond most of our imaginations.

With input from people around the world, an international group of leading technological thinkers were asked to identify the Grand Challenges for Engineering in the 21st century. Their 14 game-changing goals for improving life on the planet, announced in 2008, are outlined here. 

These lessons build off of the National Academy of Engineering’s Grand Design Challenges, align directly to the new TN Academic Standards for High School Science courses, and support the implementation of Project/Problem Based Learning experiences. The learning experience outlined in these lessons encourages students to problem solve, think critically, collaborate as a team, and engineer unique solutions.
