The National Geographic Bee (called the National Geography Bee until 2000, also referred to as the Nat Geo Bee) is an annual geography contest sponsored by the National Geographic Society.  The bee, held every year since 1989, is open to students in the fourth through eighth grades in participating schools from the United States. Andrew Wojtanik (born 1989) was the winner of the National Geographic Bee hosted by Alex Trebek in 2004, and the National Geographic World Championship in 2005.  To get to the National Geographic Bee finals, he survived two tiebreakers to advance to the final round against 13-year-old Matthew Wells of Montana, beating him to win a $25,000 scholarship.  He credits his success to a 384-page book he compiled, which is now an official study guide for the Bee, called "Afghanistan to Zimbabwe: Country Facts That Helped Me Win the National Geographic Bee", which was published in 2004.  A second edition, "The National Geographic Bee Ultimate Fact Book: Countries A to Z", was published in 2011.  Andrew lived in Overland Park, Kansas and in 2008 graduated from Blue Valley West High School.  His family has since moved to Florida. The 29th annual National Geographic Bee was held in Washington, D.C. It was sponsored by the National Geographic Society.  The State Bees were held on March 31, 2017, where the 54 finalists were determined.  The 2017 Champion, Pranay Varada, receive a $50,000 college scholarship, a lifetime membership to the National Geographic Society, and an all-expenses-paid Lindblad expedition for four to the Galápagos Islands aboard the new National Geographic Endeavour ll. Communal work is a gathering to accomplish a task or to hold a competition.  A number of cultures have such gatherings, often for the purpose of holding a competition, such as a spelling bee, or for providing manual labour, such as in a barn raising, or quilting bee. The 27th National Geographic Bee was held on May 11–13, 2015 in Washington, District of Columbia.  It is sponsored by the National Geographic Society.  The winner was Karan Menon of John Adams Middle School in Edison, New Jersey, who won $50,000 in scholarships, a trip for 2 to the Galapagos Islands, and a lifetime membership to the National Geographic Society.  The runner-up was Shriya Yarlagadda of Grand Blanc East Middle School in Grand Blanc, Michigan who won a $25,000 scholarship.  The Third place winner was Sojas Wagle of Springdale, Arkansas, who won $10,000 in scholarships.  Finishing in 4th place was Tejas Badgujar of Pennsylvania.  The competition started with the school level rounds, in which more than 5 million students competed in 11,000 schools across the nation.  Other students who placed in the top ten include Kapil Nathan of Alabama, Nicholas Monahan of Idaho, Patrick Taylor of Iowa, Abhinav Karthikeyan of Maryland, Lucy Chae of Massachusetts, and Shreyas Varathan of Minnesota.  The Florida State Champion, Rishi Nair, became the 2016 National Geographic Bee Champion.  The winners of the school bees then took a written qualification test to see who could qualify for the state level competition.  The top 100 or so scorers on the qualification test in each state were selected to go for the state championship.  The winners of the state championship would then get $100 in cash, a National Geographic 10th Edition Atlas, and the opportunity to represent their state in the National Finals held in Washington, DC. The 20th National Geographic Bee was held in Washington, D.C. on May 21, 2008, sponsored by the National Geographic Society.  The final competition was moderated by Jeopardy! host Alex Trebek.

The National Geographic World Championship (previously called the International Geography Olympiad, which is now the title of another similar competition for older schoolchildren) is a biennial, two-day-long international geography competition typically held in late July or early August.  The Championship was first held in 1993, and is sponsored by the National Geographic Society.  Teams of three students plus one alternate are selected from among those who finished highest in their respective countries' national competitions (e.g. the National Geographic Bee in the U.S.A., the Olimpíada Geográfica Argentina in Argentina or the Australian Geography Competition in Australia).  On the first day of competition, these teams take a written test on which all members confer and work together, then take part in a team geography skills-testing activity, such as using a map to find specified locations in unfamiliar surroundings.  The scores from these two events are tallied, and the top three teams advance to the final round on the second day.  The final round consists of questions primarily in the style of the National Geographic Bee, as a moderator (since 1993, Alex Trebek) reads questions to one team or one individual at a time.  These questions may also involve the use of visual aids such as maps or photographs.  Members of the top three teams receive bronze, silver, or gold medals for finishing third, second, or first, respectively.
