**__50 points – Due Monday, February 6, 2011 at the beginning of the period__** //Although it’s winter, your group has been charged with preparing for a PV end-of-year barbeque. All 1201 PV students are expected to attend. Your goal is to provide a list of all items you will need to make enough burgers for 1201 based on the information provided below and the cost of the food for the BBQ. The Sophomore class has $1,700 in its treasury – is that enough money to purchase all of the food?//

 * A survey was taken of the student body asking them what type of burger they would like. They responded as follows:
 * 19.97% want hamburgers
 * 40% cheeseburgers
 * 24.03% bacon cheeseburgers
 * 15.99% double cheeseburgers
 * Based on last year, plan that each person will eat 1.4 burgers and that each person will only have one type of burger.
 * Each hamburger has:
 * Each cheeseburger has:
 * Each bacon cheeseburger has:
 * Each bacon double cheeseburger has:
 * Buns come in packages of one dozen
 * Expect one out of every two-dozen buns is moldy and unusable. Each package costs $2.00


 * Frozen patties come in boxes of two dozen
 * Expect freezer burn on 1.3 out of 4 dozen patties – those patties are unusable. Each box costs $13.00


 * Cheese comes in blocks of 5 pounds that is supposed to have 145 slices/block. Each block costs $25.00


 * Packages of bacon contain 19 slices; each package costs $2.50


 * One head of lettuce can provide enough for 25 slices; each head is $2.00


 * One tomato can provide enough for 11 slices; each tomato costs $0.50

**__YOUR TASK__** **You will create a Group Wikispace with __links__ for the following items listed 1-3 below. Give your group a name that as well as your class period as the name of the site (e.g. BACON Period 3!!). All project requirements must be completed at the beginning of the period Monday, February 6, 2011 for full points:** **(See attached grading rubric)** **1)** **Google Doc Spreadsheet (you cannot use Excel or Numbers) - the grocery list using a spreadsheet**   - **Columns and rows must be properly formatted and clear**    - **Include only boxes, jars, blocks, heads of lettuce, etc.**    **2)** **Google Doc Document - all calculations must be shown using the “Equation” function in Documents of Google Docs in dimensional analysis form** **3) Google Doc Presentation – your group will prepare 5-10 slides defining the problem, explaining how you solved the problem including a sample calculation, the grocery list, and the cost to the Sophomore class.** Names: ____________________________________________________________
 * One jar of pickles contains 16 pickles and each pickle can provide 17 slices; each jar costs $4.00


 * __General Planning of Mini PBL__**


 * __Period 1__**

1. Group selection and preparation of a Group Contract – use the template on my Schoolwires site as a starting point. This will need to be completed and uploaded to your group Wikispace on the first day. Administration of group activities and devolution of responsibilities also needs to be done quickly. Consider the following approach:

You will need to identify who needs to do what by which day so as to remain on target for a timely completion, leaving some group ‘face-time’ for editing and discussion. The best way to do this is to prepare a concept map (flow chart) and attach it to your Group Contract. You will NOT want to allocate all calculations to ONE person, all spreadsheet activities to ANOTHER, etc. Rather, consider assigning calculations for each type of burger to one group member, switch papers and then have a different person responsible for Google Doc Equation formatting (likely evening work). Switch work again and only then consider assigning each group member the task of uploading results to the spreadsheet.

At this point of the exercise, all your data should be uploaded in rough form to the Google Doc Spreadsheet. Assign 2 group members to prepare spreadsheet functions to do the calculations. Remember, these values must match the data contained in the equations contained in the Google Doc. The other 2 group members should begin work on the Presentation by discussing/preparing the general outlook of the slides. Be sure to seek input from your other group members.

Evening Work - group members will need to: a. Setup Group Wikispace and invite group members and Nilsen (include editing ability) b. Setup Group Google Doc and invite group members and Nilsen (include editing ability) – Link to group Wikispace c. Setup Group Google Doc Spreadsheet and invite group members and Nilsen (include editing ability) – Link to group Wikispace d. Setup Group Google Doc Presentation and invite group members and Nilsen (include editing ability) – Link to group Wikispace


 * __Period 2__**

1. Pen/paper/calculator calculations should begin by all group members. Use dimensional analysis. If not completed in class, consider the importance of having it done for the next day


 * __Period 3__**

1. Upload of paper calculations using ‘equation’ formatting in Google Doc.


 * __Period 4__**

1. Upload of results to Google Doc Spreadsheet 2. Preparation of spreadsheet functions to summarize data


 * __Period 5__**

1. Analysis of results and discussion of presentation formats/responsibilities 2. Presentation preparation – don’t forget that your presentation needs to be recorded.


 * __Period 6__**

1. Final editing/discussion of completed project with assignment of last minute activities for weekend. Identification of online (real time) meeting on weekend to go over last minute details.

**__Monday__** – beginning of class – final work ready to go – no editing possible
