QR Challenge: Microbiology

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

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

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

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!

Questions / Answers (teacher reference)

Question	Answer
1. how are viruses, bacteria, and parasites alike?	They can infect a host and cause disease.
2. What is a major difference between an epidemic and a pandemic?	An epidemic affects fewer people than a pandemic.
3. Several people contract the same flu-like symptoms in a particular city. Other cases with the same symptoms show up across the state but the concentration remains localized in a few original cities. Some cases turn up elsewhere in the nation but doesn’t catch on everywhere. In the cities where the flu-like symptoms rate remains more than you would expect to normally see would be an example of an epidemic. How could this scenario turn into a pandemic?	It could spread to more people or to more locations.
4. Are viruses living or non-living?	non-living
5. What kind of cells are bacteria?	prokaryotic
6. What are viruses composed of (give 2)	DNA/RNA and a protein coat
7. What do viruses need to reproduce?	A host cell
8. What generally happens to a host cell after a virus uses its enzymes and organelles to reproduce?	dies
9. List 3 ways viruses can be transmitted.	human contact, insect bite, water
10. What is used to prevent viruses?	vaccines
11. What kind of cells are bacteria?	prokaryotic
12. Why are bacteria so prolific?	Because they can live in a variety of places, including extreme environments
13. A bacterial population can double very quickly, what makes this possible?	Bacteria reproduce using binary fission.
14. What is used to treat bacterial infections?	antibiotics
15. What is the problem that we are having with the overuse of antibiotics?	Overuse is causing antibiotic resistance.
16. Are fungi eukaryotic or prokaryotic?	eukaryotic
17. What is the difference between eukaryotic and prokaryotic cells?	eukaryotic have membrane bound organelles which prokaryotic do not.
18. Fungi reproduce both asexually and sexually, describe the advantages of both types of reproduction.	asexually offers quick, one individual and sexual offers genetic recombination which offers adaptations to the environment
19. Other than attacking us directly, what other hazards do fungi cause humans (minimum 2)?	attack our food source and mold spore allergies
20. What is a parasite?	an organism that feeds on another individual
21. Give an example of how a parasite is specifically adapted to its host.	the tapeworm does not have an intestinal track
22. How are an epidemic and a pandemic different?	An epidemic is not as widespread as a pandemic. An epidemic also affects less individuals than a pandemic.
