Cost Comparisons
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 calculations, they graph their results to compare how costs change depending on the use of different materials (steel vs. concrete). They conclude by creating a proposal for a city bridge design based on their findings.

Lunar Lollipops
The students work in teams of two to discover the relative positions of the Earth, Sun and Moon that produce the different phases of the Moon. The students will be given a Styrofoam ball that they will attach to a pencil so that it looks like a lollipop. This ball will be the Moon, the students will be the Earth and a hanging lightbulb will be the Sun. The students will move the “Moon” around them to discover the different phases. They will fill in the position of the Moon and its correspond

Improving West Corridor Design
This lesson uses the FasTracks Living Lab, a web portal to interactive train (transit) traffic data for a major metropolitan city. In this lesson, students will first evaluate whether a particular section of the transit system is functioning in an efficient manner and whether it is meeting design requirements. Then, students will suggest design improvements and evaluate whether they make a positive impact on the performance of the transit system. Throughout this lesson, students will work with r

3.3 Summary of Section 3

  1. E. coli has a remarkable method of obtaining iron from its environment, which involves the use of very powerful iron chelators, called siderophores.

  2. One siderophore in particular, enterobactin, forms an extremely stable complex with iron(III).

  3. The high stability of this complex is due partly to the rigid, preorganised structure of the ligand, and partly to the iron(III) being the correct size and charge to be chelat

3.2 Search engines and subject gateways

Although both search engines and subject gateways will help you find the resources that you need, the types of information that you find will differ.

Search engines such as Google and Yahoo! search the internet for keywords or phrases, and then show you the results. These results are not mediated by the search engines, and therefore you need to use your own judgement on the reliability of the results. You may, for example, find websites written by experts, alongside websites written by

2 A 4.6 billion-year history

Climate change is a natural process of warming and cooling that has occurred all through the Earth's history. Throughout geological time there have been ‘hot-house’ periods and ice ages. In order to understand the current situation, it is necessary to have some sense of context and perspective, from historical and geological time-scales. The document below shows a chart showing a generalised temperature history of the Earth.
