Science Content Knowledge Who Got There First? The North Pole Controversies By Laura Kissel and Lynn Lay If you want to go somewhere you've never been, what do you do first? Pull up MapQuest on your web browser and input your destination? Or, do you have a GPS unit for your car? Maybe you use a printed map or an atlas. Back in the early days of polar discovery, none of these tools were available. In fact, much of the Arctic and Antarctic wasn't even mapped yet. COMPETING CLAIMS In 1909 a bitter controversy involved two American explorers, Frederick A. Cook and Robert E. Peary. Both claimed to be first to reach the North Pole on foot. Finding the North Pole is tricky. Unlike the South Pole, which lies on a land mass, the North Pole is actually in a vast sea covered by floating ice. Since the ice is constantly in motion, planting a flag or otherwise marking the spot is futile. In addition, magnetic compasses are rendered useless in the polar regions due to the magnetic field at the poles. Determining one's position, then, is based on

calculations using a chronometer - basically a highly efficient time piece and a sextant - a navigational instrument that allowed an explorer to compute latitude based on the position of the sun. In September of 1909, Frederick A. Cook, a medical doctor from New York, announced that he and two Inuit companions had reached the North Pole on April 21, 1908. He claimed that bad weather conditions and drifting ice had prohibited his southward return and he and his companions were forced to winter over in an ice cave. A week later, Robert E. Peary, a civil engineer and a commander in the U.S. Navy, announced that he had reached the North Pole, accompanied by his long-time companion Matthew Henson, and he denounced Cook as a fraud. In any case, Peary had some very powerful sponsors, including the New York Times as well as the National Geographic Society. Though Cook appeared to welcome Peary's announcement and was willing to share the limelight, Peary was furious at Cook's attempt to "steal" his victory. By all accounts, Peary was a driven man, and this was his third attempt at the North Pole. Henson, an African-

Science Content Knowledge American, had traveled with Peary on all of his "farthest north" expeditions. Though Peary recognized Henson's contribution to his success, stating, "Henson was the best man I had with me for this kind of work," he also minimized Henson's role after the fact. Complicating the situation for Cook was that his claim to have been the first to summit Mt. McKinley (in Alaska) in 1906 had been called into question. Cook's critics felt that if he lied about Mt. McKinley, then certainly he was lying about the North Pole as well. It didn't take long for Peary's claim to overshadow the claim of the rather unknown Cook.

today, when travelers might blog about their journeys to places unknown, taking hundreds of digital images and video along the way, polar explorers in 1909 were much more limited by their tools. Even radio transmission was limited during this time period; explorers had to get to the nearest populated city in order to share their discoveries with the world. A lot of research and attention has been given to the Cook/ Peary North Pole controversy over the last 90 years. Each side has its supporters as well as detractors. Some researchers have concluded that neither one actually got to the North Pole. It is fascinating that there seems to

Shortly after they returned from the Pole, Cook and Peary each published their version of the truth in books that discussed their expeditions and discoveries in minute detail. The books became bestsellers and also fueled the public debate. The burden of proof for polar discoveries lies on the explorer. Without modern methods of GPS mapping and plotting of locations, how was this done? Polar explorers during this time were expected to keep detailed, handwritten diaries of their travels, including navigational calculations. Unlike

be no end to the debate in sight, even after all of these years. Researchers continue the hunt for primary documents that might lead them to the answers. The Byrd Polar Research Center Archival Program holds the papers of the Frederick A. Cook Society, while Cook's diaries and other personal papers are held in the Library of Congress in Washington, D.C. Robert E. Peary's papers can be found in the U.S. National Archives in Washington, D.C. CONTINUING CONTROVERSIES The North Pole controversy does not end with Cook and Peary; fast forward from 1909 to 1926. By this time, technological advances changed the focus of polar exploration. Simply getting there was no longer the primary goal; scientific study of the polar regions included geological investigation, advances in radio transmission, weather observation, and continued mapping of the vast Arctic and Antarctic regions. Richard E. Byrd, officially retired from the U.S. Navy, was a proponent of aerial investigation. He earned his pilot's wings after an injury to his foot forced him to redirect his naval career. After participating in the Greenland Expedition of 1925, Byrd believed more than ever in the feasibility of flight in the Arctic.

Byrd was the commander of the aviation unit on this expedition. Though bad weather and mechanical breakdowns hampered the success of flight on the Greenland Expedition, Byrd continued to have faith that airplanes would indeed be successful in investigation of the polar regions. In 1926, with the backing of the National Geographic Society and private donations from many influential people of the time, such as Edsel Ford, John D. Rockefeller, Vincent Astor, and others, Byrd was able to secure enough money to lease a ship and buy an airplane and all the needed supplies to embark on a north polar flight. Other major investors included the New York

Times, Current News Features, and Pathe News, a producer of newsreels. In exchange for their investments, Byrd signed contracts guaranteeing his story to the various media. After extensive organization and planning, delays and complications, Byrd finally took off in his plane, the Josephine Ford, on May 9, 1926, at 12:30 a.m. Floyd Bennett did most of the piloting, with Byrd as navigator. The aerial navigator's role was complex, operating several instruments at a time. The sun compass (developed specifically for Byrd by Albert Bumstead of the National Geographic Society) was used to determine direction, a chronometer to find longitude, a bubble sextant for latitude, and smoke bombs and drift indicator to determine the influence of

Byrd received numerous honors for this accomplishment and became a public hero. The National Geographic Society examined Byrd's records and confirmed his navigational calculations and instrumentation as accurate. Almost immediately, however, some were skeptical of Byrd's accomplishment. Most doubters based their concern on the belief that the Josephine Ford was incapable of making the round-trip flight in only 16 hours. The most vocal skeptics came forward after Byrd's death in 1957. One even stated that Byrd's pilot, Floyd Bennett, confessed that he and Byrd had actually flown out of sight and circled until enough time had passed for Byrd to claim they had made it to the North Pole. The North Pole flight controversy simmered for decades after Byrd's death. It was reignited in 1996 when an Ohio State University archivist, Raimund E. Goerler, discovered Byrd's North Pole expedition diary among Byrd's papers. The Byrd papers came to the Ohio State University in the mid-1980s, but remained unprocessed until the

Science Content Knowledge 1990s, when a U.S. Department of Education grant provided the funding to process the collection. The diary went undiscovered for a time, probably due to the printed title, 'Diary, 1925. ' Indeed Byrd did use the diary in 1925; however, since he did not write on all of the pages, he used it again in 1926 and in 1927. Sometimes he corrected the printed date at the top of the page and sometimes he did not. Most entries are written in pencil and the entries are out of order chronologically. Some pages have notes and mathematical calculations, while several pages

show signs of erasure, though the erasures are not thorough and can easily be read. There are notes written by Byrd to his pilot Floyd Bennett, during the flight, due to cockpit noise which made it difficult to communicate verbally. It is apparent that Byrd used the diary as both a daily journal and a convenient notepad. In light of the discovery of the diary, the existing evidence was analyzed and reanalyzed. Some believe that the erasures present evidence that Byrd was lying about achieving the Pole; others believe that this simply shows that he made a calculation error

Science Content Knowledge NATIONAL SCIENCE EDUCATION STANDARDS: SCIENCE CONTENT STANDARDS The entire National Science Education Standards document can be read online or downloaded for free from the National Academies Press web site. The content standards are found in Chapter 6, http://books.nap.edu/openbook.php? record_id=4962&page=103. While explorers are usually part of a geography or social studies curriculum, including lessons on polar explorers (past and present) can also meet the History and Nature of Science Content Standard for grades K-4 and 5-8: K-4 History and Nature of Science Science as a Human Endeavor • Science and technology have been practiced by people for a long time. • Men and women have made a variety of contributions throughout the history of science and technology. • Although men and women using scientific inquiry have learned much about the objects, events, and phenomena in nature, much more remains to be understood. Science will never be finished. • Many people choose science as a career and devote their entire lives to studying it. Many people derive great pleasure from doing science. PIGICEBERGS.

5-8 History and Nature of Science Science as a Human Endeavor • Women and men of various social and ethnic backgrounds - and with diverse interests, talents, qualities, and motivations - engaged in the activities of science, engineering, and related fields such as the health professions. Some scientists work in teams, and some work alone, but all communicate extensively with others. • Science requires different abilities, depending on such factors as the field of study and type of inquiry. Science is very much a human endeavor, and the work of science relies on basic human qualities, such as reasoning, insight, energy, skill, and creativity - as well as on scientific habits of mind, such as intellectual honesty, tolerance of ambiguity, skepticism, and openness to new ideas. History of Science • Many individuals have contributed to the traditions of science. Studying some of these individuals provides further understanding of scientific inquiry, science as a human endeavor, the nature of science, and the relationship between science and society. • In historical perspective, science has been practiced by different individuals in different cultures. In looking at the history of many peoples, one finds that scientists and engineers of high achievement are considered to be among the most valued contributors to their culture.

Literacy Content Knowledge Differentiating at the Nonfiction Cafe By Tracey Allen and Clarissa Reeson It seems that, wherever we go, we are always developing different ways to reach our students in order to help them achieve. In fact, it happened again just the other night when we met for dinner at a local restaurant. The restaurant is known for being quite a culinary experience. It is different from the steak and seafood restaurants our husbands love, and vastly different from the pizza parlors our daughters enjoy. Once we were seated, we carefully began perusing the menu, looking for the entrée that would satisfy our palates. As we both gave our orders, we felt a sense of pleasant anticipation of what was to come. We had selected different entrées, similar appetizers, and the same beverage. At this point we both realized that, although we recognize the power of choice and decision-making in our personal lives, we rarely offer our students that gift in the classroom setting.

We understand that selecting foods in a restaurant is far different from learning in a classroom, but the idea of “choice” is the same and ultimately empowering to the individual. We would never expect all of our students to choose the same entrée from a menu; however, day after day we give students the exact same activity to complete without taking into consideration their learning styles or preferences. Why is that? This need for choice led us to develop a learning menu that would be meaningful, flexible and empowering to each learner. Our “Nonfiction Cafe Menu” (see Resources to the right) can easily be integrated with any nonfiction text. As indicated on the front of the menu, each student has $50 to spend at the café and must choose a balanced meal (i.e., one item from each category). As students peruse the menu and decide on an activity to complete, they inevitably choose a task that interests them, thus creating a desire to delve into their task with vigor. It is this power of “choice” that awakens the desire for all students to learn and ultimately succeed.

By Stephen Whitt What is the most isolated place on Earth? One good answer is a mountain chain at the bottom of the Arctic Ocean. Two miles below the frozen surface of the Arctic Ocean lies the Gakkel Ridge. It is one of the most difficult places on Earth to explore. Think about the obstacles. First, there are two miles of very cold water on top of it. The pressure of all this water is enormous. An ordinary submarine would be crushed like an eggshell. Second, the water at this depth is pitch-black. If you want to see here, you'll need to bring your own light. Third, there's a thick block of ice

between the water and the sky. If you need to come to the surface quickly, you'll likely find a wall of ice between you and the nearest oxygen. And yet scientists are now exploring this new frontier. The scientists can't visit the Gakkel Ridge themselves. Instead, they send robots. The names of these robots don't make one think of cold water or deep oceans. PUMA stands for "plume mapper." This robot uses sound, lasers, and chemical sensors to spot underwater volcanic plumes (the black smoke that rises from volcanoes). JAGUAR is PUMA's partner. Once PUMA spots a plume, JAGUAR travels to the spot. JAGUAR hovers over the plume, gathering images and information. The robots work with little direction from the scientists on

the surface. PUMA and JAGUAR are dropped into the water through a hole in the ice. Hours later, the robots must, on their own, find that hole once again. If the hole would only stay in the same place, the job would be easier. But ice moves. The hole might have drifted several miles, might have changed shape, might even have closed up since the robots went into the water. Even worse, it is difficult to communicate through water.

The scientists say it is easier to operate a robot on Mars than to keep track of their robots below the ocean. Radio waves easily travel through empty space. Water absorbs radio waves. In warm water, that problem can be solved with a tether. But in an ice-covered region, shifting ice sheets can snap tethers. If that happens, the robot is lost. Without tethers or radio waves, PUMA and JAGUAR have to be smart. They must make good choices. They must decide where to go and what to study.

And what have the scientists and their amazing robots found? Wonder! The animals of the Gakkel Ridge have been isolated for millions of years. In that time they've changed in unexpected ways. Perhaps the most exciting animal sighting was a new kind of Dumbo octopus. Flaps that look like elephant ears project from the creature's head. The octopus gently moves its flaps to swim. One day another animal swam into the view of the robotic camera. This animal looked like a sea cucumber with a fish's tail. Scientists still have no idea what this creature might be. Gakkel Ridge's volcanoes are still active. Since 1999 three of Scientists use a helicopter to find PUMA and JAGUAR. Photo courtesy of Woods Hole Oceanographic Institution.

Instead, it is left over from the eruptions of these hot, active, underwater volcanoes. Today we send robots to faraway planets and moons. Yet there are still places to discover right here on Earth. The Gakkel Ridge is one of those amazing places.

Across the Curriculum: Lessons Exploration Comes to Life with Orienteering, Geocaching By Jessica Fries-Gaither Bring the essence of exploration to your classroom with hands-on activity such as orienteering and geocaching. Both provide opportunities for students to learn about exploration by developing compass and map skills. Orienteering involves using a compass and a map to travel from one point to another. Geocaching, on the other hand, involves using a GPS (global positioning system) device to locate "caches," or containers, that hold a logbook and small prizes. The finder signs the

logbook and may elect to take an item from the cache, replacing it with another item. Hundreds of thousands of caches around the world are tracked online at the official geocaching web site, http:// www.geocaching.com/. Both orienteering and geocaching are popular hobbies, and teachers should find a wealth of resources and enthusiasts in their local areas. While incorporating these types of activities can require extra time and effort (and possibly even a field trip), teachers can find support through local orienteering clubs or geocaching enthusiasts. Individuals may be available to conduct presentations or help design and run an activity for students. Some clubs and parks offer orienteering activities for families as well. Ask parents at your

school - you might be surprised to find several geocachers and orienteers represented! Orienteering and geocaching clearly align with social studies standards involving the use of maps, but they can tie into other curricular areas as well. Math, reading, and writing are often incorporated into these activities, as are physical education and cooperative learning. Teachers can extend the literacy components of both activities by having students write directions or create a class geocaching book to document the activity or leave at a cache. Most simply, orienteering and geocaching allow students to practice the skills and experience the concept of exploration firsthand. We've provided links to some resources that may help you incorporate orienteering and geocaching into your classroom.

Science & Literacy: Lessons Lessons and Activites About Exploration By Jessica Fries-Gaither Including a unit on polar explorers in your curriculum can do much more than engage students with a fascinating subject and meet social studies standards. You can incorporate discussions of technology, both past and present, and scientific principles such as astronomy, ecosystems, and environmental change. The study of explorers is also based on literacy skills reading, writing, and discussion all naturally align with this type of unit. Finally, lessons might also target the History and Nature of Science content standard, of the

National Science Education Standards as many explorers also made detailed observations of the environment and conducted scientific studies while traveling or after returning from an expedition. In this article, we've highlighted lessons and activities about exploration in general as well as polar explorers. We've identified resources that go beyond the traditional research assignment, such as creating a scrapbook, a papier-mache map of an expedition, or an explorer's tool kit. A little creative thinking will go a long way in terms of engaging students and incorporating higher-order thinking skills into the unit. Some other ideas for enhancing your study of explorers:

• Compare and contrast two expeditions (historic and modern-day, in different locations) orally, using a graphic organizer, or in writing. • Create a video re-enacting an expedition or a significant discovery. • Conduct a mock interview of an explorer - as a skit, video, podcast, or newspaper or magazine article. • Discuss how the success of an expedition should be evaluated. Many expeditions failed to meet their initial goal, but made unexpected, yet significant, discoveries along the way. Should these expeditions be considered successful? Why or why not?

Since ancient times, people have wondered about what would be found in the northernmost and southernmost parts of our world. Later, many men and women risked their lives hoping to find something there that would make them wealthy or famous. Even today scientists and travelers take risks to learn a little more about the secrets these frozen places hold. One of the last great mysteries on Earth.

ARCTIC EXPLORATION

I, Matthew Henson: Polar Explorer. Carole Boston Weatherford. 2008. Nonfiction Picture Book. Grades K-5. Double-page pastel illustrations show the many obstacles-both physical and socialthat Matthew Henson faced before realizing his dream of reaching the North Pole. The large pages are perfect for reading and sharing aloud. Keep On! : The Story of Matthew Henson. Deborah Hopkinson. Nonfiction Picture Book. Grades 1-5.

The Search for the Northwest Passage. Jill Foran. 2005. Nonfiction. Grades 4-5. Offering vocabulary words, a timeline and a comprehension quiz, this book presents the historical motivation for seeking the Northwest Passage and the explorers who hoped to make their fortune by finding it. Even today, the Northwest Passage has limited usefulness as a trade route, but with global warming impacting the ice packs, the passage may be open for more months out of the year.

Off The Bookshelf ANTARCTIC EXPLORATION You Wouldn't Want to Be a Polar Explorer! Jen Green. 2000. Nonfiction. Grades 3-5. Readers take part in Ernest Shackleton's expedition to cross Antarctica by way of the South Pole. His ship becomes stuck in the ice and the crew is forced to haul their belongings behind them in sleds made of lifeboats. Crew members are lost when ice thaws and cracks in half in the middle of camp. Other treacherous events are detailed, and the reader learns some of the techniques the explorers used to survive. Comic-bookish illustrations make this an enjoyable read.

Discovering Antarctica: The People. June Loves. 1998. Nonfiction. Grades 3-5. Surprisingly, Antarctica was a mystery to European explorers and was not officially sighted or mapped until 1820. Students will learn about Captain James Cook's initial voyages inside the Antarctic Circle, the first explorers to set foot on "land," and the race to be the first expedition to find the South Pole. Today Antarctica is the site of international, collaborative research, with multiple bases where scientists gather data. Photos and maps show students the locations of historically significant expeditions and how camps have evolved technologically over time.

POLAR EXPLORATION

Polar Explorers for Kids. Maxine Snowden. 2004. Nonfiction. Grades 2-5. This book presents polar explorers chronologically and offers hands-on activities in each chapter. Women Explorers in Polar Regions. Margo McLoone. 1997. Nonfiction. Grades 3-5. Beginning by defining what an explorer is and the challenges explorers face, this book introduces readers to five explorers most of us have never heard of. From gold-rush heiress Louise

Boyd to travel writers Agnes Cameron and Ida Pfeiffer, to nurse Kate Marsden, to modern-day athlete Helen Thayer, each woman had reasons for traveling to the poles. Polar Exploration: Journeys to the Arctic and Antarctic. Martyn Bramwell. 1998. Nonfiction. Grades 3-5. This DK Publishing book provides an overview of exploration in both polar regions. Students will appreciate the numerous colorful illustrations, diagrams, and quotes from explorers.

Off The Bookshelf Into the Ice. Lynn Curlee. 1998. Nonfiction. Grades 4-5. From the ancient Greeks and Romans to the Europeans and Americans, the North Pole was a mysterious place to be conquered for its resources and potential for swift trade routes. Unprepared for the harsh environment, many missions failed due to poor diet, disease and lack of resources. Boats became trapped and crushed by the ice packs; some explorers attempted to travel over the ice on skis. Swedish explorer Salomon Andree even tried to travel by balloon. Made easier by the invention of the airplane, exploration turned to the South Pole in the early 1900s.

Pioneering Frozen Worlds. Sandra Markle. 1996. Nonfiction. Grades 4-5. So what do scientists do at the poles, anyway? Learn what technology has allowed scientists to explore the poles and what they are studying. The poles are a great place to test robots and vehicles for space exploration. Scientists study polar animals-what they eat and where they go. Scientists are learning about ice and how it melts. Core samples are being taken to study the climate and geological history of our planet. There's a whole lot going on in the coldest places on earth!
