1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.
2. If their phone camera doesn't automatically detect and decode QR codes, ask students to
4. Cut them out and place them around your class / school.
1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.
2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.
3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. 1. With around 68 percent of all people living with HIV residing in sub-Saharan Africa, the region carries the greatest burden of the epidemic | AIDS1 | 2. 2. A common cause of the spread of HIV is through husband to wife; men often work for months away from home, patronize prostitutes while away, and pass HIV to their wives when they return home | AIDS2 | 3. 3. Poor medical care, inadequate nutrition, and cultural resistance to sex education complicate efforts to deal with this epidemic | AIDS3 | 4. 4. The Republic of South Africa, one of the most developed countries on the continent of Africa, has the largest number of people with HIV/AIDS | AIDS4 | 5. 5. In many countries of sub-Saharan Africa, AIDS has erased decades of progress made in extending life expectancy. Average life expectancy in sub-Saharan Africa is now 54.4 years and in some of the most heavily affected countries in the region life expectancy is below 49 years | AIDS5 | 6. 6. The social and economic consequences of the AIDS epidemic are widely felt in the health sector but also in education, industry, agriculture, transport, human resources and the economy in general | AIDS6 | 7. 7. The effect of the AIDS epidemic on households can be very severe, especially when families lose their income earners. In other cases, people have to provide home based care for sick relatives, reducing their capacity to earn money for their family. Many of those dying from AIDS have surviving partners who are themselves infected and in need of care. They leave behind orphans, who are often cared for by members of the extended family | AIDS7 | 8. 8. The HIV and AIDS epidemic has dramatically affected labor, which in turn slows down economic activity and social progress. The vast majority of people living with HIV and AIDS in Africa are between the ages of 15 and 49 - in the prime of their working lives | AIDS8 | 9. 9. Investing in HIV/AIDS education is one of the most significant steps that can be taken to reduce the spread of this disease, especially investing in female education | AIDS9 | 10. 1. Desertification is the degradation of arid or semi-arid land | DES1 | 11. 2. Over 250 million people are directly affected by desertification | DES2 | 12. 3. About 1 billion people in over one hundred countries are at risk including many of the world\'s poorest, most marginalized, and politically weak citizens | DES3 | 13. 4. Desertification, like that in Chad, is caused largely by over-farming, overgrazing, deforestation and bad irrigation practices | DES4 | 14. 5. The Sahel is a semi-arid region on the southern border of the Sahara desert that is turning into arid desert for the reasons listed in 4 | DES5 | 15. 6. Africa is the worst affected continent; with two-thirds of its land either desert or drylands. Almost a third of land in the U.S. is affected by desertification; and one quarter of Latin America and the Caribbean, and one fifth of Spain | DES6 | 16. 7. The areas affected find it virtually impossible to raise food to feed its people resulting in migration to other areas, putting more of a burden on those areas | DES7 | 17. 8. Education of farmers and herders in order to improve land management practices is one strategy in combating the causes of desertification | DES8 | 18. 9. The Green Belt Movement in which bands of trees are planted to try to hold down valuable topsoil and fight erosion has had mixed results | DES9 | 19. 10. Deforestation and desertification contribute to the albedo effect in which the sun\'s rays, instead of being absorbed by the ground such as tree cover, reflect back into the atmosphere, contributing to Global warming | DES10 | 20. 1. Deforestation is clearing Earth\'s forests on a massive scale, often resulting in damage to the quality of the land | DEF1 | 21. 2. Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama are lost each and every year | DEF2 | 22. 3. The biggest driver of deforestation is agriculture where farmers cut forests to provide more room for planting crops or grazing livestock | DEF3 | 23. 4. Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. Loggers, some of them acting illegally, also build roads to access more and more remote forests—which leads to further deforestation | DEF4 | 24. 5. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees | DEF5 | 25. 6. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes | DEF6 | 26. 7. Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor back into the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts | DEF7 | 27. 8. Trees also play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests means larger amounts of greenhouse gases entering the atmosphere—and increased speed and severity of global warming | DEF8 | 28. 9. In their drive to modernize in the 20th century, nations like Brazil have allowed mass deforestation to occur, even though it has slowed down in recent years | DEF9 | 29. 10. Responsible cutting with new tree plantations is a possible compromise in this drive to modernize | DEF10 | 30. 1. Preventing the shipment of narcotics from Latin America labs to North American criminal distributors has been a major goal of the United States in recent decades | NAR1 | 31. 2. One of the world\'s largest suppliers of illegal narcotics, Colombia leads the world in production of cocaine | NAR2 | 32. 3. Under colonial rule, the Spanish encouraged the production of cash crops in Colombia, primarily coffee | NAR3 | 33. 4. After Colombia won its independence in the 19th century, Colombia\'s economy was still restricted by this reliance on one or two cash crops which makes the country very vulnerable to world market and weather conditions | NAR4 | 34. 5. The growth of the Medellin and Cali drug cartels in the late 20th century led to an increase in farmers being given coca to grow instead of coffee | NAR5 | 35. 6. These drug cartels invested in their own private armies, airplanes, ships, labs, and processing plants | NAR6 | 36. 7. The term narcoterrorism arose to describe the campaigns of violence used by the drug cartels against government and civilian targets; resulting in the murders of hundreds of political and military officials | NAR7 | 37. 8. Colombia has been further disturbed by warfare waged by left-wing guerrilla groups since the 1960s - one of the most famous being FARC | NAR8 | 38. 9. These guerrilla groups and the paramilitary groups that fight against them are financed by the drug trade | NAR9 | 39. 10. In the 21st century alone, the US government has invested over $5 billion in aid to combat the drug trade with military measures such as training Colombian soldiers and providing combat helicopters | NAR10 |
