  1. 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...

  2. Build an Approximate Scale Model of an Object

    02 Aug 2010 | Learning Objects

    Students will create a model of an object of their choice, giving them skills and practice in techniques used by professionals. The students will use sketches as they build their objects. This...

  5. Close Enough?

    02 Aug 2010 | Learning Objects

    Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the...

  6. 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...
