2.3 Corrosion processes
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.

Molly Brown: Biography of a Changing Nation
The true story of Margaret Brown transcends the limitation of myth, revealing a woman of extraordinary spirit and complexity who embodied the issues of her times and the power of individual action. This reformer worked hard to make a difference and her confidence made it possible for her to help others and this 2:30 video helps explains these. Unfortunately, it just touches on them so this video could be used as a discovery lesson since it includes reformers, mining, and even the Titanic.

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.

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

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
