Putting It All Together (Piat): Making the Case for Currency

PUTTING IT ALL TOGETHER (PIAT): MAKING THE CASE FOR CURRENCY

UNIT 1

To Begin:

Re-read the PIAT introduction on pages 22 - 23 of your textbook, then read the detailed assignment on pages 143-44**.

Overview:

For this PIAT, you will evaluate the benefits and drawbacks of adopting a new design for dollar currency. Your challenge will be to convince the U.S. public to accept the currency that you design. The rationale for your choice of material and design must be supported by the chemistrythat you have studied and the information gathered from reliable Web sites. Note the URLs provided for your reference at the end of your presentation and write-up.
Good starting point:

1. Presentation Portion:

This is a3 minute summary for your proposal (oral or slide show, webpage, etc..), with draft pictures (or 3D print out!) of your currencydesign. Also highlight relevant information about your choice of materials (either pure or alloys) including:how they are found in nature, where, process of obtaining the raw materials, lifespan, cost, and various physical and chemical properties.

2. Written Proposal:Please type up your responses to the questions on pages 143-144. *Note, you do not have to do a publication or discuss strategies to ease the transition of your new design. Please do include the following additions:

Include size, shape, and percent composition of your currency.
Include only TWO balanced chemical reactions that occur in the processingof the ore/s needed to create your currency.
Using the TWO balanced equations and stoichiometry, show how much ore you would need to create one unit of yourcurrency based on how much of that metal (in grams) will be in one coin. Show your calculations.

Evaluation:

Your performance will be evaluated according to these standards. The boxed area should be the bulk of the presentation.

1)Recommendation – what is your currency design? Brief overview of your rationale for choice in materials.

2)Rationale – coin design-factors influencing decision – chemistry involved in process and stoichiometry based off of percent composition and weight of coin.

3)Environmental Implications – gathering raw materials, life span, waste involved in refining, transport, and production

4)Advocacy Plan – identify concerns and address them, suppose you are asked to present the proposal in from of a judged panel (make your arguments convincing).

All materials must be typed, not handwritten (except chemical equation and stoichiometry work).
