A WebQuest for 9th Grade (Algebra I) Designed by Richard Hung, Diego Onuchic, Terri Vu
 * Speed for Your Price**



 **Introduction** You'll be getting your driver's license soon and may be looking into buying a car. Today, you have a lot of options with a variety of cars. Some will be more expensive than others, but with that increase in price comes a number of benefits. For a lot of us, a car's top speed is one of the most important deciding factors in whether or not to purchase the car. How will you decide what car to buy with price and speed in mind? In this webquest, it will be up to you to find the most cost effective car.

 **The Task** From a list of cars, your job is to choose 10 of the given cars. Using the links, you will compile a list of prices and top speed for your group's 10 cars. You will then compare the price of the cars to their speed and determine which of the cars you would choose as the most cost effective.

 **The Process**

Here are the steps:
 * 1) You will be assigned to a team of 3 students.
 * 2) Decide as a group which 10 cars the team would like to research
 * 3) Together, you will find the price and speed of one car
 * 4) Calculate the ratio of price / top speed
 * 5) Record all your data in a table similar to the one below[[image:http://img822.imageshack.us/img822/3936/tabletechclass2.gif]]
 * 6) You will then individually repeat this process for 3 of the remaining 9 cars
 * 7) As a team, you will create a scatter plot with the ratios that you have found
 * 8) Together, decide which car is the most cost effective
 * 9) Write a brief paragraph explaining the choice of your car and how you've made your decision. Questions that you may consider:
 * How did your group decide that this car was the most cost effective?
 * Would you purchase this cost effective car?
 * Is there another car that is not as cost effective, but you would rather buy that than the one you have chosen?

Now that you know what you'll be doing. Here is the list of all the cars you can choose from:
 * BMW M6 2007
 * Cadillac CTS-V 2007
 * Chevrolet Corvette 2007
 * Ferrari Scaglietti 2007
 * Jeep Grand Cherokee 2006
 * Lamborghini Muricielago 2007
 * Lincoln LS 2006
 * Lincoln Mark LT 2006
 * Mercades GL-Class 2007
 * Porsche 911 GT-3 2007
 * Porsche Cayman 2007
 * Toyota Land Cruiser 2006
 * Volvo S60 2007

Once your group has chosen 10 cars, use the links below to find the price and top speed of the cars:

 **Evaluation** You will be graded together as a group based on:
 * 1) Completion of your table
 * 2) Accuracy of your graph
 * 3) Explanation of your decision

 **Conclusion** In this activity, you used the web to look up data for your cars. You also calculated ratios and created a graph based on those ratios to determine which car is the most cost effective. You had to report your most cost effective car and explain whether or not you would purchase that car. From this exercise, we will move on to learning about word problems that involve ratios.
