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. It is estimated that in 1996, the population of the “third world” was 4.6 billion, or about 79 % of the total world population;in 1996 the world’s population was estimated to be 5.8 billion people and growing at a rate of 1.8%;if the third world’s population is growing at a rate of 2.1%, use the equation A = 4.6e^.021t to determine what part of the world’s population the third world will be in the year 2025? | 86.5% | 2. 2. In 1947 an Arab Bedouin herdsman climbed into a cave near Qumran on the shores of the Dead Sea;he found some earthenware jars containing what we now know as the Dead Sea Scrolls;the wrappings of the scrolls were analyzed and found to contain 76% of their original Carbon-14;estimate the age of the scrolls? | 2268.7 | 3. 3. The half-life of a radioactive substance is 8 minutes;how long does it take 80 grams of this substance to decay to 7 grams? | 28.1 | 4. 4. A colony of staph bacteria grows from a population of 600 to 4500 in 12 hours;find the rate of growth using this equation A = A(subzero)e^rt? | 16.8% | 5. 5. 100 grams of a radioactive substance decays at the continuous rate of 4% per hour;how long will it take until 25 grams remain? | 34.7 | 6. 6. 100 grams of a radioactive substance decays at the continuous rate of 4% per hour;what is its half-life? | 17.3 | 7. 7. How long will it take a population to double if it increases at a rate of 5%? | 13.9 | 8. 8. How long will it take a population to double if it increases at a rate of 15%? | 4.6% |
