NEES Teaching Demonstration: Earthquakeproof K'nex Buildings
23 Jun 2011  Learning Objects  Contributor(s): Jason Lloyd, NEES EOT
Students will be able to observe two ways engineers counter seismic accelerations on highrise strucutres on order to make them safe. This demonstration will need to be made ageappropriate by the...

Feel the Stress
05 Aug 2010  Learning Objects
Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical...

Load It Up!
05 Aug 2010  Learning Objects
Students take a handson look at the design of bridge piers (columns). First they brainstorm types of loads that might affect a Colorado bridge. Then they determine the maximum possible load for...

Spaghetti Bridge
05 Aug 2010  Learning Objects
Civil engineers design and construct structures such as buildings, dams, and bridges. We can explore the field of engineering by making a bridge using spaghetti. This bridge is then tested based...

Swing in Time
05 Aug 2010  Learning Objects
Students examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the...

Breaking Beams
02 Aug 2010  Learning Objects
Students learn about stress and strain by designing and building beams using polymer clay. They compete to find the best beam strength to beam weight ratio, and learn about the tradeoffs...

Breaking the Mold
02 Aug 2010  Learning Objects
In this math activity, students conduct a strength test using modeling clay, creating their own stress vs. strain graphs, which they compare to typical steel and concrete graphs. They learn the...

Construction Technologies: Construct the Strongest Bridge
02 Aug 2010  Learning Objects
In this activity, students will work in pairs to create three simple types of bridges. They will observe quantitatively how the bridges work under load and why engineers use different types of...
