The Goofy Golf Ball

A Geometry PBL

Company Name Group Members:

THE SITUATION

You and your team are members of a large golf ball manufacturing company in Costa Rica! Your company has put together you and your team of experts to create a new package to sell their golf balls making sure that it is creative and stands out to customers, but that also is cost-effective and maximizes the use of the space. Your challenge is to design a golf ball package that is cost-effective and functional, but that also is attractive to potential customers.

Your design team will decide on a shape and material for the package you would like to design. You will use your knowledge of surface area, volume, and other geometry skills to help make the best decision as a group. You must balance between creating a low-cost package and a fancy design that will attract customers..

Once you have decided on 3 possible package designs, your team will collaborate and create a multimedia presentation which incorporates why you chose each design, the mathematics used in the creation of the package, and which design is your number one choice. You will propose your golf ball package design to the board of directors. Each member of the group must be part of the presentation.

Golf Ball and Package Material Information

A standard golf ball has a diameter of 42 mm. Use the space below and/or extra paper to calculate the size and shape of the packages you will design. Think about the appropriate length, width, and height of the package that will allow a space-efficient design. You must choose a material with which to design your package. However, different materials have different costs. Not only do you need to take into account the cost of your package, but you also want to think about the quality of the materials used and the marketing effect you want to have with your clients. Recycled Cardboard (standard brown color): $0.01 per square mm Clear plastic: $0.02 per square mm Colored Plastic: $0.03 per square mm Single Colored Cardboard (any one color): $0.04 per square mm Multiple Colored Cardboard: $0.05 per square mm Use the space below to calculate the cost of building your package designs.

Design #1 Planner 1. Which geometrical shape will you use for this design?

2. Formula for Surface Area

3. Material Cost of each package design

4. Formula for Volume

5. Number of Golf Balls each package will hold

6. The Unit Rate (cost per golf ball) of each design

7. The Art behind the design

8. The Appeal to the customer

9. Since the golf balls are spheres, there will be space left over in any package. Calculate how

much of this wasted air space will be left inside your package.

Presentation Planning Sheet Audience: Board of Directors STEP ONE – DRAFT INTRO: Discuss your purpose. Briefly introduce your 3 golf ball package designs. PARAGRAPH 1, 2, and 3: Describe each package design. Include the measurements of Volume and Surface Area, as well as the creative design process used to make the product more appealing to customers. Make sure to include the cost of each design based on the materials used PARAGRAPH 4: Decide as a group which of the 3 designs is your preferred golf ball package. Sell it to the board of directors, and make sure to include the reasons why you feel that this design is better than the other to. CLOSING: Briefly thank the board members for their time, and make your final remarks. Turn in your first draft document to the group folder.

Draft document written by STEP 2 – REVISE Proofread together with a second group member. Look for mistakes, spelling and grammar errors, things that don’t make sense, etc. Make sure all required information was included. Turn in your revised document to the group folder.

Draft document revised by STEP 3 – PUBLISH: Produce your writing in an electronic copy. The third group member should proofread carefully and look for mistakes and spelling/grammar errors. Make sure all required information was included. The electronic document will be turned in with the final product.

Extension Activity

1. A standard shipping container is a rectangular prism with dimensions 20cm x 16cm x12cm.

Take into consideration the shape of your individual golf ball package. How many of your

packages can fit into one of these boxes? Show your calculations.

2. How much unused space will be left in the shipping container?
