2.1 Introduction
The I-35W bridge collapse in Minneapolis in August 2007, resulting in at least 13 deaths, illustrates the importance of structural integrity. This unit looks at the investigation that followed the collapse of the Silver Bridge over the Ohio River in 1967 which demonstrates how the study of safe design and the assessment of components and structures under load is of increasing importance in engineering design.

1.2.9 Reading diagrams: questioning what they say

With each of these diagrams and others we are trying to read there is another set of more searching questions we can ask:

  • What is the purpose of the diagram, i.e. what is it aiming to tell us?

  • How is the information imparted?

  • What assumptions does it make about our ability to understand it?

  • What are we expected to remember from it?

  • How successful is

1.2.8 Working with other people's diagrams – reading diagrams

Reading diagrams is an equally useful skill to that of drawing diagrams. Not only does it help you understand what other people are trying to convey, it also helps you be critical of the diagrams you draw yourself. In some cases diagrams are used to make the text look pretty or appealing and do not add to the understanding of the reader (hopefully not the case with the diagrams here!). Even when they are used more effectively there is a need to be critical of what information is being conveye

Kidney Filtering
In this activity, students filter different substances through a plastic window screen, different sized hardware cloth and poultry netting. Their model shows how the thickness of a filter in the kidney is imperative in deciding what will be filtered out and what will stay within the blood stream.

Focus on Fabrics: Putting Materials to Good Use
The goal is for students to understand the basics of engineering associated with the use, selection, and properties of fabrics. A wide variety of natural and synthetic fibers are used in our clothing, home furnishings and in our travel and sports equipment. The specific material chosen for each application depends on how closely the properties of the material match the design needs. This unit focuses on the different characteristics of fabrics and shows students how natural and synthetic fabrics

Ecologists now accept human beings and our activities as a significant influence on the Earths ecology. ASTER data is being used to better understand urban ecology, in particular how humans build their cities and affect the surrounding environment. Will Stefanov of Arizona State University will present the first set of ASTER images of the urban skeleton of the amount of built structures in 12 cities around the world and discuss the Urban Environmental Monitoring project which will examine 100 ur

Jakobshavn Glacier Retreat (WMS)
Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2003, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. For starters, as more ice moves from glaciers on land into the ocean, it raises sea levels. Jakobshavn Isbrae is Greenlands largest outlet glacier, draining 6.5 percent of Greenlands ice

Researchers and forecasters often study sea surface temperatures for an activity predictions for 2003 in part to changing conditions in the Pacific Ocean, such as the demise of El Nino. This sequence traces the evolution of the warmer-than-normal waters associated with the weak El Nino that developed in the late fall of 2002. By January, the warm conditions began to dissipate. Fewer than normal hurricanes generally form when El Nino is present. Researchers say the Pacific may transition to the c

These figures have been adjusted to match United Nations totals. The most dramatic differences in population are not readily visible in this animation because they are located in cities. The maximum population density in 1990 was about 79,000 people per square kilometer, while the estimated maximum population density in 2015 will be about 236,000 people p
