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. Atom | The smallest unit of an element | 2. Boiling Point | Temperature at which a liquid changes to a gas at a given pressure | 3. Chemical change | A change that occurs when one or more substances change into entirely new substances with different properties. | 4. Conservation of matter | the principle stating that matter is not created or destroyed during a chemical reaction | 5. Compound | A substance made up of atoms of two or more different elements joined by chemical bonds | 6. Chemical Reaction | the process by which one or more substances change to produce one or more different substances | 7. Chemical Property | a characteristic of a substance that can be observed ONLY when the identity of the substance is changed | 8. Density | mass/volume | 9. Element | A pure substance made of only one kind of atom | 10. Equation | A symbolic representation of one set of compounds reacting together to form a new set of compounds | 11. Endothermic Reaction | chemical reaction in which heat energy is absorbed | 12. Exothermic Reaction | A chemical reaction in which heat energy is given off | 13. Freezing point | Temperature at which a solid changes to a liquid at a given pressure | 14. Formula | An expression of compounds reacting together to form a new set of compounds | 15. Gas | State of matter composed of freely moving molecules capable of indefinite explanation | 16. Physical Change | A change in the physiucal properties of a substance, which is usually reversible | 17. Group | Elements that occur in a vertical column on the periodic table; also called a family. | 18. Homogeneous Mixture | A mixture that is evenly mixed; also called a solution | 19. Heterogeneous Mixture | A mixture that is unevenly mixed | 20. Indicator | Something that produces an observable physical change but still retains its original form. Some of these changes may include the appearance or disappearance of a color. | 21. Law of Conservation of Mass | A law that states that matter cannot be created or destroyed during a chemical reaction. The mass of the reactants is equal to the mass of the reactants. | 22. Liquid | State of matter composed of freely moving molecules that do not usually separate | 23. Metal | An element below and to the left of the stair-step line of metalloids; about 80% of the known elements are metals | 24. Mass | The quantity of matter within an object | 25. Molecule | A group of atoms bonded together, often represented the smallest unit of a compound | 26. Metalloid | An element with properties of both metals and nonmetals located along the stair-step line on the right side of the periodic table | 27. Mixture | The physical combination of 2 or more substances; can be separated by physical means | 28. Malleability | The ability to be hammered into a sheet | 29. Nonmetal | An element above and to the right of the stair- step line of metalloids | 30. Period | Elements that occur in a horizontal row on the periodic table | 31. Property | A characteristic of a substance that can be observed | 32. Physical Property | A characteristic of a substance that can be observed without changing the identity of the substance | 33. Periodic Table | A chart illustrating chemical elements that compose all physical matter listed by atomic number and related groups | 34. Precipitate | A solid separate from a solution | 35. Physical Science | A branch of natural science involving matter or energy | 36. Solution | A homogenous mixture of two or more substances ( a substance is dissolved into a solvent) | 37. Suspension | A mixture of fluid and other particles, which are undissolved | 38. Solid | State of matter composed of tightly packed molecules, resting in a firm substance |
