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 |
