This unit is the fourth in the MSXR209 series of five units on mathematical modelling. In this unit you will be taken through the whole modelling process in detail, from creating a first simple model, through evaluating it, to the subsequent revision of the model by changing one of the assumptions. The problem that will be examined is one based on heat transfer. This unit assumes you have studied Modelling pollution in the Great Lakes (MSXR209_1), Analysing skid marks (MSXR209_2) and Developing

What is ‘e-commerce’? This unit will look at typical application areas including the internet, supply chain management and online auctions. It will also help you to understand the underlying technologies used to implement e-commerce applications before looking at some of the problems that can be encountered when developing distributed e-commerce systems.
Being able to understand and use a range of numerical, graphical, algebraic and other mathematical techniques is a central feature of number skills. Use the following list to help you identify the areas you may need to work on. Will you need to:
make observations, measurements, and express and combine the units of measurement correctly?
read and interpret scale drawings, graphs, tables and charts? If so, do you need to learn about the

A decade ago, the possibility of a link between the MMR vaccine and autism hit the media. Fear of the vaccine spread rapidly and, despite an almost unanimous consensus that the claim was unfounded, still persists today. In this unit, we’ll examine why this controversy took on such a life of its own and why parents still agonise about the vaccine.

Deep Content: Guide to Effective Searching of the Internet
This outstanding website is, without question, one of the most comprehensive online resources for learning efficient Internet search techniques. The guide begins with some fairly non-technical background about the Internet and explains why searching such a massive amount of information is more complex than it seems. The general process used by search engines to rank webpages is described. After covering the fundamentals of search engine operation, the guide discusses some best practices to use w
Education Module: Space Technology is Used to Observe and Measure Tectonic Motion of the Earth's Sur
This educational resource, provided by the Southern California Integrated Global Positioning System (GPS) Network, provides instruction, exercises, and projects that illustrate how space technologies are used to predict and measure earthquakes. Using these resources, students can learn about plate tectonics, earthquakes, and satellite technologies. These resources are intended for secondary school or undergraduate students, but the explanations are simple enough that educators of younger childre
Beat the Heat at Arizona Science Center
TryScience.com offers an unique energy learning activity called Beat the Heat. This fun and interactive lesson lets users design a house in a particular location and test it in various seasons to best utilize the heat of the sun for energy efficiency. You can choose various types of roofs, windows, solar panels, skylights, and plants, as well as the direction your house faces, to see how each of these variables effects your home's efficiency. This in-depth and intriguing exercise teaches some ve
Digital Signal Processing Tools
A collection of seven Java applets and associated tutorials are available on this site from the Signals and Systems Group at the University of Edinburgh. The tools illustrate various concepts of digital signal processing, like convolution, correlation, the Fourier transform, and discrete-time applications of each. Seven other applets that demonstrate more advanced concepts are also available, but no documentation or explanation accompanies them. A few conference publications and reports related

Earth Science Week
The American Geological Institute organizes Earth Science Week (ESW) each year in October "to help the public gain a better understanding and appreciation for the Earth Sciences and to encourage stewardship of the Earth." The website offers highlights, evaluations, and news clippings of past ESW events. During the months leading up to ESW, users can search for Earth Science events taking place in their area. Teachers can find numerous classroom activities for grades K-12 based in the National Sc
Design a Parachute
After a discussion about what a parachute is and how it works, students will create a parachute using different materials that they think will work best. The students will test their designs, which will be followed by a class discussion (and possible journal writing) to highlight which paper material worked best.
