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. any substance, often a protein, that induces an allergy | Allergen | 2. a Y-shaped protein on the surface of B-cells that is secreted into the blood or lymph in response to an antigenic stimulus, such as a bacterium or virus | Antibody | 3. a type of lymphocyte that, when stimulated by a particular antigen, differentiates into plasma cells that synthesize the antibodies that circulate in the blood and react with the specific antigens | B-cell | 4. differentiated plasma cells that secrete a specific antibody and a clone of memory cells that make the antibody on subsequent encounters. | Clones (of plasma cells) | 5. a physiologically active amine found in plant and animal tissue and released from mast cells as part of an allergic reaction in humans. It causes the dilation of capillaries, constriction of bronchial smooth muscle, and decreased blood pressure | histamine | 6. a cell hybrid produced in vitro by the fusion of a lymphocyte that produces antibodies and a myeloma tumour cell in order to produce a continuous supply of a specific antibody. | hybridoma | 7. a type of lymphocyte that is released as a specific immune response and is stored in case of a second exposure to the same antigen | Memory cell | 8. any of the highly specific antibodies produced in large quantities by the clones of a single hybrid cell that has been formed in the laboratory by the fusion of a B-cell with a tumour cell | Monoclonal antibodies | 9. an agent that causes disease or illness in another organism. | Pathogen | 10. a fully differentiated B-lymphocyte (white blood cell) that produces a single type of antibody | Plasma cell | 11. an acute, highly infectious, often fatal disease caused by a poxvirus. It is characterized by high fever and aches, and is believed to have been eradicated globally by widespread vaccination | Smallpox | 12. a type of white blood cell that completes maturation in the thymus and that has various roles in the immune system, including the identification of specific foreign antigens in the body and the activation and deactivation of other immune cells | T-cell | 13. a preparation of a weakened or killed pathogen, such as a bacterium or virus, or of a portion of the pathogen's structure that stimulates antibody production or cellular immunity against the pathogen once administered, but is incapable of causing severe infection | Vaccine |
