  1. 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...

  2. Load It Up!

    05 Aug 2010 | Learning Objects

    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...

  3. Straw Bridges

    05 Aug 2010 | Learning Objects

    Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with...

  4. Bridge Types: Tensile & Compressive Forces

    02 Aug 2010 | Learning Objects

    Students explore how tension and compression forces act on three different bridge types. Using sponges, cardboard and string, they create models of beam, arch and suspension bridges and apply...

  5. 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...

  6. Cost Comparisons

    02 Aug 2010 | Learning Objects

    Students learn about the many types of expenses associated with building a bridge. Working like engineers, they estimate the cost for materials for a bridge member of varying sizes. After making...
