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. Welcome! In this scavenger hunt, you will learn about a place in our solar system that has shown promising life-supporting evidence. Search for the QR codes in numbered order, and scan for questions and answers. | Q1 | 2. Saturn! It's small icy moon Enceladus has water and other biological elements that show promise for sustaining life. | What planet has a moon that has promising potential for sustaining life? | 3. Enceladus has a diameter of 314 miles. Tiny! For scale, it could fit inside the state of Arizona. | How big is Enceladus? | 4. Enceladus is 790 million miles from Earth. | How far are we from Enceladus? | 5. The moon has an extremely cold climate, with temperatures getting as low as -330 degrees Fahrenheit. Despite this, it still maintains liquid water on the surface. | What is Enceladus' climate like? | 6. Aside from atmospheric qualities, Enceladus remains at such low temperatures because the surface of the moon reflects sunlight rather than absorbing it and trapping the heat that it provides. | Why is Enceladus so cold? | 7. Cassini! The Italian spacecraft was able to orbit Saturn and it's moons and capture detailed images of Enceladus, among other moons. | How did we get such detailed information about Enceladus if it is so small and far away? | 8. Enceladus' ocean is actually below the moon's icy crust. The rocky core of Enceladus does in fact generate enough energy to keep the sub-surface ocean in a liquid state. | If the surface of Enceladus is so cold, why doesn't it's liquid water freeze? | 9. There has also been hydrogen found spewing from below the moon's surface, which is essential to life. The subsurface ocean has been found to contain hot spots where colonies of bacteria and small organisms could thrive. | Is an ocean below the surface of Enceladus actually enough evidence to determine that it could sustain life? | 10. The large amount of hydrogen in the atmosphere puts into question whether or not there are any current inhabitants. If there were organisms using the hydrogen, there wouldn't be nearly as much free in the atmosphere. | Is there evidence that there are currently organisms inhabiting Enceladus? | 11. Probably not. Temperature would be a big problem, and there would need to be other biological elements necessary on Enceladus for human life to be supported. | Could humans ever inhabit Enceladus? | 12. The next step is to get back to the moon, with a lander capable of actually testing for life forms and getting additional information, as well as analyze samples from the surface. | Now that we know about Enceladus, what's next? | 13. Thanks for taking part in the Enceladus scavenger hunt!What did you learn? | Done. |
