Date: Friday, April 3, 2009
Times: 9- 9:50 and 10- 10:50 a.m. CDT
Grade Levels: 5-12
Videoconference Description: The bridge has been designed, public hearings have been held, and funding has been arranged. Now the construction begins in earnest. Join RoundTrips live from the construction site of the new bridge going over the Missouri River at Glasgow, Missouri. Interact with construction personnel as they share how they are bringing the design plans to life. How is the superstructure for the bridge connected to the bridge piers? What kind of materials are used? How is the structure welded together? How are the supports put in place for the road surface to come? What items are pre-fabricated and what is created on site? How does the installation occur? What are the careers involved in building a bridge? For the answers to these and other questions, join RoundTrips for the sixth program in our continuing series of programs produced with the Missouri Department of Transportation as they build a new bridge over the Missouri River at Glasgow, Missouri.
A new RoundTrips videoconference has been announced! Here are the details:
Date: January 30, 2008
Times: 10 to 10:45 a.m. and 11:15 a.m. to Noon
Grade Levels: 4-8
Cost: No Fee
When you travel you notice there are all sorts of different shapes to bridges that span rivers, gorges, and highways. Have you ever wondered “Why did they build that kind of bridge here?” This interactive videoconference is designed to help you and your students answer that question. We’ll explore basic bridge shapes such as arch, beam, suspension, and cable-stayed. We’ll look at the forces of tension, compression, torsion, bending and shear that act on those bridge shapes. We’ll investigate how the purpose of the bridge, its geographic location, and materials used in its construction also help determine its final design. This is the second of our ten part series developed with the Missouri Department of Transportation as it builds a new bridge across the Missouri River at Glasgow, Missouri. Students will see examples of different types of bridges and engage in interactive discussion and activities with engineers who design and build bridges. We’ll look at examples of bridges from around the world and the specifics of the new bridge being built at Glasgow.
