Achievement Task

You are a member of a promotion team working for the University of Ontario. You were hired to make a presentation to Doppler Tech Incorporated on the various applications of Doppler Radar. Doppler Tech currently manufactures radar guns for the OPP and is interested in expanding their business within the radar technology field. Your research should focus on the various uses of radar. As a member of the team you (and your group) will focus on one of the many applications for this technology. Rely on the rest of your team members to gather information about other devices. You will present your findings to a panel of research and design personnel from Doppler Tech.

Part A: Research

1. Who was Doppler? When did he first discover the Doppler effect? What was the significance of the discovery?
2. View the simulation at www.pearsoned.ca/physics11. Draw a diagram to summarize how wavelength and frequency are involved in the Doppler effect.
3. When was radar first discovered? What role did this technology play in World War II?
4. You and your team should develop a list of technologies that utilize radar technology and/or the Doppler effect. Write a one or two line summary for each type of technology.
5. Once the whole group has created a suitable list of technologies to investigate, break into smaller teams and begin detailed research on the technology you are assigned.
6. Address the following…
   1. State the function of the device or technology.
   2. Who is credited for the invention of the technology.
   3. How does the technology make use of the Doppler effect in performing its stated function?
   4. Provide a diagram to illustrate how frequency and wavelength are involved in the operation of the device or technology.

Part B: Testing and Inquiry

In order to gain a better understanding of what the Doppler effect is develop a demonstration that involves the Doppler effect. Remember the Doppler effect can be seen as using anything that exhibits wave properties. (ex. water in a ripple tank, sound waves etc.) Your demonstration could be a model that properly illustrates the effect rather than a full working set-up.

Part C: Analyze and Reflect

Using your own criteria, consider the effects that funding your technology would have on modern society. Remember that Doppler Tech is looking for a new project to fund. Their money is limited so you need to sell the merits of your device or technology.

Part D: Communicate

Summarize the results of your research and organize the information into a poster. Your poster should be aimed at the research and development department of Doppler Tech. You will be given 5 minutes to highlight the important information on your poster. Remember you audience. You want to explain the technology, but you also need to sell the research and development department of the merits of funding your project.
