Simulations For Teaching Concepts On Washington State, Cynthia Louise Buettgenbach

All Graduate Projects

Simulation lessons and materials were developed to teach concepts on Washington State to a classroom of fourth grade students. The activities in which the students participated were the following:

1) planned trips to the five geographic regions of Washington State;

2) became part of an Indian tribe and held a meeting with other tribes at Sacajawea Park;

3) played a board game, traveling with Lewis and Clark to the Pacific Ocean;

4) held mock state elections and one legislative session.

Students showed an increased interest in social studies through the simulations.

G82-623 An Overview Of Concrete As A Building Material, David P. Shelton, James M. Harper

University of Nebraska-Lincoln Extension: Historical Materials

The general properties of concrete are discussed, as well as its components and their proportions. Includes decisions customers should consider before using concrete.

Concrete, specifically portland cement concrete, has the qualities of strength, durability, versatility, and economy, and can be placed or molded into virtually any shape and reproduce any surface texture. It is the most widely used construction material in the world. In the United States almost twice as much portland cement concrete is used as all other construction materials combined.
