NEES Teaching Demonstration: Earthquake-proof K'nex Buildings
0.0 out of 5 stars
23 Jun 2011 | Learning Objects | Contributor(s): Jason Lloyd, NEES EOT
Students will be able to observe two ways engineers counter seismic accelerations on high-rise strucutres on order to make them safe. This demonstration will need to be made age-appropriate 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!
Students take a hands-on 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...
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
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...
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 trade-offs...
Breaking the Mold
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
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...
