Aurum Naturae Exit Store !"#$%& Gold is located on the Main Level The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 1 Exhibition Introduction Gold October 22, 2010– March 6, 2011 Gold tells the fascinating story of the world’s most desired metal, exploring its natural beauty, scientific value, and its power to shape history. A vast array of extraordinary objects including natural gold specimens of crystallized gold, enormous nuggets, gold bullion, coins from shipwrecks, gold bars, exquisite jewelry, and contemporary objects such as Olympic medals and an Oscar statue illustrate the manifold ways in which gold has captivated the imagination of generations past and present. Gold delves into humankind’s enduring fascination with this elusive metal, looking at how people have searched for it, stolen for it, fought for it, and used it to create scientific breakthroughs. Main Themes The following themes are threaded throughout the Gold exhibition and may be useful in framing how the exhibition connects with your curriculum: 1. Although it is extremely rare, gold is found on all continents and is prized above all other metals for its combination of unusual properties. 2. Through the centuries, gold became a symbol of wealth, luck, power and magic across cultures. 3. For thousands of years, gold has played an important part in human society as a medium of exchange—as money.

The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 3 Gallery Overviews Aurum Naturea Its Latin name, aurum, means “glowing dawn.” Elemental, Pure, and Rare Gold is rare; gold crystals are even more rare. The specimens of gold crystals in this section are presented, with the exception of some cleaning and preparation, just as they were found. Gold is one of the few minerals that occurs in a nearly pure, or native, state. Putting Down a Deposit In nature, gold deposits occur as veins or as placers. Most crystalline gold comes from hydrothermal fluid, extremely hot water rising from deep in Earth. As the fluid moves through openings in Earth’s rocky crust, tiny amounts of gold dissolve into it. Then, as the fluid flows through cooler rocks near the surface, the gold precipitates, or is drawn out of the fluid, and settles in cracks to form veins or lodes. Over millions of years, gold flakes and grains worn away from veins are swept into bodies of water. The heavy gold settles in bodies of water, forming placer deposits. Invisible Gold Microscopic particles of gold can also be extracted from rocks. After gold-bearing rocks are pulverized, the gold is recovered using chemical processes. Nearly 40 percent of all gold ever mined was recovered from South African rocks. Infinite Variety Gold nuggets are solid lumps of gold. Nuggets are often named for their appearance. Guiding Questions 1. Where is gold found in nature? In the cracks of rocks, gold is found as veins or lodes. Over millions of years, gold flakes and grains worn away from veins are swept into bodies of water. Gold settles in these stream-, lake- and riverbeds, and on the sea floor, forming placer deposits. Microscopic particles of gold can also be found in rock samples. Nuggets are rare, making up less than 2 percent of all native gold ever mined. 2. What characteristic suggests that a gold nugget was found in a vein or placer deposit? How do gold crystals differ? Rounded surfaces of gold nuggets show that they were worn smooth in streams or rivers and collected from placer deposits. Gold crystals appear in more complex arrangements such as wire, leaf or branched forms. Colorado Gold Specimen This delicate, crystallized gold specimen was found in Leadville, Colorado and formed from superheated gold-bearing water. Crystallized gold specimens like this are extremely rare in nature. ©Denis Finnin/AMNH The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 4 Gallery Overviews Incomparable Gold Gold, by any standard, is unusual. Gold Properties Gold’s beauty, value and its many other unique qualities make it the material of choice in many industries. Gold is dense, ductile, malleable, highly reflective of heat and light and conducts heat and electricity. Karats are a measurement of gold’s purity; a karat is 1/24 part, by weight, of the total amount. Pure gold is described as 24 karats. Treasure of Five Continents Gold has been mined from most countries on Earth. Although the mineral occurs in many different types of rock and ore deposits, almost all gold mined on Earth is native gold, gold in a pure or nearly pure state. Most crystallized gold samples are recovered from quartz- and calcite-rich veins and lodes. Earth’s Surprise Package Frog Ornament Metalworking techniques spread to Mesoamerica—the region that today includes central Mexico through Costa Rica—around 800 C.E. The Mixtec people became the greatest gold workers in the region. Part of the American Museum of Natural History’s prestigious collection, this Mixtec gold ornament is in the form of a frog (c. 1200¬–1521). ©C. Chesek/AMNH More than 90 percent of all gold ever used has been mined since 1848, when gold was discovered at Sutter’s Mill, California, but the lure of gold has been felt since the beginning of human civilization. Visible gold deposits are increasingly rare, so new exploration techniques must rely on the physical and chemical characteristics of gold deposits. Gold Mining and the Environment Today, the global demand for gold is higher than ever. Mining remains the primary means of satisfying this demand—but there are environmental costs to all mining—and gold mining in particular. Guiding Questions 1. What are some unique properties of gold? Gold is highly reflective of heat and light. Gold is ductile: it can be drawn out into the thinnest wire. Gold conducts electricity and heat. Gold is prized for its beauty. Gold is malleable. 2. How do humans use gold? The visors of astronauts’ space helmets receive a coating of gold to reduce glare and heat from sunlight. Most gold—78 percent of the yearly gold supply—is made into jewelry. Gold is used as a contact metal in the electronics industry as it is a good conductor of electricity and heat. Gold can be flattened into extremely thin sheets and used to cover a surface, an ancient technique called gold leafing or gilding. The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 5 Gallery Overviews Golden Ages Gold was one of the first metals to be worked by humans. Gleaming nuggets of gold were easy to find and collect from stream banks, and were easily shaped with simple tools. Through the centuries, gold became a symbol of wealth, luck, power and magic. The importance of gold in the civilizations of every era makes all ages “golden.” They Took It With Them: Ancient Times In much of the ancient world, owning gold was the exclusive right of nobility. The Egyptians filled the tombs of their pharaohs with gold to support them in the afterlife. Crossroads of Gold: The Ancient Middle East Since the Sumerians of Mesopotamia first worked gold for sacred and decorative objects 5,000 years ago, the ancient Middle East has been a center of gold work as well as the crossroads for trade to Asia, Africa, and Europe. The Sun on Earth: African Gold The Akan people formed the powerful Asante state in the late 1600s, in what is today the nation of Ghana. By the mid–1700s, the Asante state had gained control over trade in gold, textiles and slaves. The Gold of Enlightenment: Asia-China, Japan and the Himalayan Kingdoms Inka Figure A hollow gold Inka figurine from Peru was probably used as an offering and was originally wrapped in cloth. ©Denis Finnin/AMNH Among many cultures in Asia, owning gold was the privilege of the highest classes. Gold was the secret treasure of wealthy merchants or was used in temples. A Woman’s Worth or a Sign of Royal Birth: South and Southeast Asia The peoples of South and Southeast Asia have mined gold for thousands of years and used it with skill since ancient times. Today, India is the world’s largest consumer of gold. Gold of South America: Sweat of the Sun Gold in the Americas was a prized material for objects of adornment. It was also valued for its religious symbolism. For the Inca and other peoples of the Andean region of South America, gold was the “sweat of the sun,” the most sacred of all deities. But it was gold’s value as money that drove European exploration and colonization of the New World. Gold of North and Central America: Sacred Brilliance Gold was valued by the Indigenous peoples of Central and South America, but not as money. These peoples equated the metal with sacred brilliance and power. The Gilded Age of Gold: Europe and America 19th and 20th Century Whether furnishing the home or accessorizing the person, gold objects signaled the owner’s high social status as well as his high income. The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 6 Gallery Overviews Guiding Questions 1. In what ways did ancient civilizations connect gold to the sun and deities (gods)? In Akan thought (Sub-Saharan West Africa), gold is considered an earthly counterpart to the sun and the physical manifestation of life’s vital force, or kra. For the Inca and other peoples of the Andean region of South America, gold was the “sweat of the sun,” the most sacred of all deities. In the Aztec language, the name for gold is teocuitlatl, which means “excrement of the gods.” 2. How was gold used as a symbol of status in different cultures? The Egyptians filled the tombs of their pharaohs with gold to support them in the afterlife. In Peru, ornaments such as gold plumes were attached to headdresses or crowns worn by priests or political leaders. Royal Inca women fastened their garments with large gold pins known as tupus. A Mixtec noble wore a gold labret—a lip ornament that fit into a slit cut into the lower lip— and ear spools, worn in openings made in the ear lobes. In the 19th and 20th centuries, furnishing the home and accessorizing the person with gold objects signaled the owner’s high social status as well as his high income in American and European cultures. The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Keris Handle This keris (pronounced “crease”) handle found in Bali, Indonesia (c. late 1800sto early 1900s), is an example of the traditional dagger of Southeast Asia. The keris originated in Java as far back as 1400 b.c.e. © C. Chesek/AMNH, AMNH Division of Anthropology Page 7 Gallery Overviews Lost and Found For Spanish explorers and American adventurers, finding gold was only the beginning. They also had to bring it by sea to their home countries and financial centers. Hurricanes, far more than pirates or other accidents, doomed many gold-laden ships. Paths of Gold The Panama Route connected steamships in the Pacific and Atlantic oceans. These “Panama Steamers” carried almost all of the gold exported from California to eastern cities. Worth and Weight During the early years of the gold rush, private companies began to make their own gold coins to answer the need for currency. Federal coins slowly replaced privately minted ones. The first step in turning gold into money was to weigh and assay it. The assayer melted the gold in a furnace and poured it into an iron mold to form a bar called an ingot. Spanish Wrecks Reveal Their Secrets Gold Box Because gold doesn’t tarnish, this gold box recovered from the 1715 Wreck of the Plate Fleet’s San Roman off the coast of Florida looks much the same as it did before it was lost to the sea hundreds of years ago. ©C. Chesek/AMNH, Courtesy of the Florida Division of Historical Resources, Bureau of Archaeological Research In 1622, the Tierra Firma fleet left Havana bound for Spain. Eight of the vessels, sank in a hurricane, along with a fortune in gold, silver, emeralds and pearls. After a 16-year search, Mel Fisher and his treasure hunters discovered them in the 1980s. Guiding Questions 1. What is an assayer? What is an ingot? Describe the process that was used to turn gold into money. To turn gold into money an assayer, a chemist trained to test the purity of gold, melted the gold and formed a bar called an ingot. Next, the assayer cut small chips from opposite corners of ingot. The assayer performed chemical analysis of one chip to determine its purity. The other chip was the assayer’s commission. The ingot was stamped with the assayer’s information. Ingots could be used as currency in large transactions, such as banking or commercial shipments to New York. 2. What gold items have been recovered from sunken ships of the 1600s, 1700s, and 1800s? Answers may include items recovered from the 1622 wreck of the Santa Margarita that sank in the Caribbean while in route to Spain, the 1715 wreck of the Plate Fleet that sank off the Florida coast while in route to Spain, and the 1857 wreck of the S.S. Central America that sank off the South Carolina coast while in route to New York. The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 8 Gallery Overviews Gold Standard For thousands of years, gold has played an important part in human society as a medium of exchange; that is, as money. World’s Earliest Coins Early Chinese money developed from cowrie shells. True coins, made of electrum—a mineral combining gold and at least 20 percent silver —were first minted in the ancient Near Eastern kingdoms of Lydia and Ionia. As empires developed, large coins used in long-distance trade bore simple designs so that merchants all over the empire would recognize them. During the 1500s, gold currencies came into wide use in Europe. New World Coins Byzantine Coin (Front and Back) Byzantine gold Histamenon Nomis coin (1028-1034 c.e.) with a depiction of emperor Romanus III being crowned by the Virgin Mary and on the reverse, Christ enthroned. ©Craig Chesek/AMNH Gold coins in the New World were first minted in either Cartagena or Bogota, Colombia in 1622. The United States Mint began operating in 1792. Between 1776 and 1778, both the states and the federal government produced coins. After 1788, only the federal government had the right to issue coins. In 1933, President Franklin D. Roosevelt took the United States off the gold standard, but people still recognize the intrinsic value of gold. Top Drawer Storage The Federal Reserve Bank of New York holds the world’s largest accumulation of monetary gold. Only a small portion belongs to the U.S. government: the bank serves as guardian for the gold reserves of approximately 60 foreign governments, central banks and international organizations. The vault is 25 meters (80 feet) beneath the street and holds $147 billion worth of gold bullion. Guiding Questions 1. Observe the coins on display in the gallery. What are their similarities and differences? Answers will include a variety of observations related to the various sizes and shapes of the coins. Students may notice that there are pictures of rulers on many coins. Coin material varies. Early coins were gilded with bronze. Later coins were made of electrum, a mineral combination of gold and silver. Then people learned to separate gold and silver to make gold coins. 2. What is considered the most valuable coin in history? Why? In 1933, after President Franklin D. Roosevelt took the United States off the gold standard, 455,500 uncirculated double eagles ($20 gold coins) were melted into bars. Two coins were donated to the Smithsonian Institution before the rest were destroyed, but some coins were believed stolen from the mint. The Treasury Department located and destroyed nine coins; a tenth was recovered in 1996 and auctioned in 2001 for more than $7 million, making it the most valuable coin in history. The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 9 Gallery Overviews Golden Achievement From ancient times to the present day, gold has represented success. Kings, conquerors and captains of industry claimed it as a prize and bestowed it as a precious gift. Today gold is our symbolic reward for cultural achievements. In film and theater, in the music industry, in sports and athletics or for outstanding bravery, gold signals the ultimate reward. To claim the gold is to be, simply, the best. And the Winner Is … The music recording industry recognizes excellence through Gold® records and GRAMMYs. The first Gold® record was awarded to Perry Como in 1958 for his single, “Catch a Falling Star.” The first Gold® album followed shortly and was awarded to the cast of the musical Oklahoma. The Thrill of Victory Whether racing to the finish line or hurtling through space, extraordinary achievements are recognized with extraordinary trophies. Your Weight in Gold The idiom “worth its weight in gold” denotes something of immense value. Many commodities throughout history have been worth their equivalent weight in gold—salt, aluminum even black pepper. Guiding Questions 1. What are some examples of how gold is used today to recognize achievement? A gold medal is awarded for first place in the Olympics. The music recording industry recognizes excellence through Gold® records and GRAMMYs. The winner of the Kentucky Derby receives a gold trophy. Three individual 18-karat gold models of the American lunar module were made in 1969 on behalf of the French newspaper Le Figaro and presented to the three Apollo 11 astronauts during their post flight tour in Paris. The Chicago White Sox were awarded a gold trophy when they won the World Series in 2005. 2. Why are many cultural achievements recognized with gold items? Gold is a rare and therefore precious gift. It signals the ultimate reward. To claim the gold is to be, simply, the best. The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Cartier Replica of a Lunar Module Three individual 18-karat-gold models of the American lunar module were made in 1969 by the jeweler Cartier of Paris on behalf of the French newspaper Le Figaro and presented to the three Apollo 11 astronauts during their postflight tour in Paris. This model was presented to astronaut Michael Collins. ©Nick Welsh/Cartier Collection 2006 Page 10 Focused Field Trip Gold: What do you want to know?

(Early Elementary) 5.A.2a Formulate questions and construct a basic research plan. (Late Elementary) 5.C.2b Prepare and deliver oral presentations based on inquiry or research. (Late Elementary) Pre-Visit Activity To prepare students for a visit to The Field Museum’s Gold exhibition, write the word GOLD on a chalkboard or a piece of butcher paper. Ask students to share what they know about gold; record responses. Read the book Gold (A True Book) by Salvatore Tocci. Ask students to share what they learned about gold from the read-aloud; add their responses to the chalkboard or butcher paper. Have students create a two-column chart titled “Gold”; label the left column “Wonderings” and the right column “Learnings.” Have students write at least two questions they have about gold in the “Wonderings” column. Explain that students will find answers to the questions in the Gold exhibition at The Field Museum. Discuss some ways students will be able to find answers at the Museum. (Look at pictures, diagrams and maps, read the text, carefully observe objects, ask Museum docents or school chaperones for guidance). Be sure to have students bring their charts to the Museum. Field Trip Activity Before you enter the Gold exhibition, have students review the questions they wrote on their “Wonderings and Learnings” chart. Have students explore the exhibition, working to answer their “Wonderings.” As students find answers or make observations, have them add the information to the “Learnings” column. Support students as they explore the exhibition and record their findings. Have students to work in groups to promote discussion. Post-Visit Activity Encourage students to publish what they learned about gold in the form of a report, poster, exhibition review, or brochure. Give students the opportunity to share their final presentations with classmates or another audience. The Field Museum • Gold Educator Guide • fieldmuseum.org/gold Page 11 Focused Field Trip Gold: Who, What, When, Where, How Corresponds with the Golden Ages gallery Illinois Learning Standards 18.A.3 Explain how language, literature, the arts, architecture and traditions contribute to the development and transmission of culture. (Middle/Junior High School) 18.A.4 Analyze the influence of cultural factors including customs, traditions, language, media, art, and architecture in developing pluralistic societies. (Early High School) 18.B.5 Use methods of social science inquiry (pose questions, collect and analyze data, make and support conclusions with evidence, report findings) to study the development and functions of social systems and report conclusions to a larger audience. (Late High School) Pre-Visit Activity Before visiting the Gold exhibition, encourage students to think about how gold is a part of our culture. How is it used? Where does it come from? Who does it affect? What is it’s significance? Have students brainstorm ideas in peer groups. Discuss the ideas. Next, ask students to share some ways gold is a part of other cultures; list and/or share examples. Explain that students will be exploring gold’s significance to various cultures at The Field Museum. Have students create a chart for recording information at the Museum. Charts should have six columns: 1. Who (culture or people) 2. Where (continent, country, etc.) 3. When (time period) 4. How (how was/is gold significant to this culture or people) 5. What (Draw an example or describe a gold object of significance from this culture) 6. Other. Include at least two rows with ample space for writing and recording information. Field Trip Activity Before entering the Golden Ages gallery, instruct students to first walk through the gallery to make initial observations, then choose two cultures to focus on. You may want to organize students into small groups to encourage discussion. Students may study more than two cultures if there is extra time or interest. Please be conscious of traffic flow; consider rotating students through this gallery to prevent over-crowding. After visiting Gold, have students gather additional information from related permanent exhibitions (Africa, The Ancient Americas, China and Tibet Halls, Grainger Hall of Gems, etc). Post-Visit Activity Back in the classroom, ask students to share their findings. In small groups or as a class, identify similarities and differences in the way gold is used across cultures. After creating a list of similarities, encourage students to think about why: Why do these similar relationships with gold occur across cultures? Why is gold valued across time and place? What are examples of other natural resources that carry world-wide value? If time permits, have students research gold’s significance to various cultures or a different natural resource of value.
