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

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!

C. TIPS / OTHER IDEAS

4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.

Questions / Answers (teacher reference)

Question

Answer

1. This power tool consists of removing material from the workpiece by the use of a rotating wheel that has a surface composed of abrasive grainsGrinder
2. A hammer having one end of the head hemispherical and used in working metal2 Ball peen hammer2
3. This welder is used also referred to as a solid wire welder. An arc welding process which joins metals by heating them with an arc. The arc is between a continuously fed filler metal (consumable) electrode and the workpiece. Externally supplied gas or gas mixtures provide shielding3 MIG Welder3
4. This type of tool can be locked into position, using an over-center action. One side of the handle includes a bolt that is used to adjust the spacing of the jaws, the other side of the handle (especially in larger models) often includes a lever to push the two sides of the handles apart to unlock them4 Vise grips/locking pliers4
5. A tape of cloth, paper, or steel marked off in a linear scale, as of inches or centimeters, for taking measurements5 Steel tape measure5
6. a toughened steel chisel6 cold chisel6
7. A powered vertical drilling machine in which the drill is pressed to the work automatically or by a hand lever7 Drill press7
8. Welding with the heat from an oxy-fuel flame, with or without the addition of filler metal or pressure8 Gas welder8
9. These come either covered with flux, or just bare wire. In the field it is called a "rod" in stick welding, and "wire" for Mig and Flux Cored Arc Welding9 Electrode9
10. A hand clamp that holds a welding rod and conducts electricity out of the rod in DIRECT CURRENT ELECTRODE NEGATIVE, or into the rod in DIRECT CURRENT ELECTRODE POSITIVE10 Electrode holder10
11. A heavy block of iron or steel with a smooth, flat top on which metals are shaped by hammering11 Anvil11
12. A heavy clamp, usually mounted on a workbench and operated by a screw or lever, used in carpentry or metalworking to hold a piece in position12 Vise12
13. This cutting tool is used to create cylindrical holes, almost always of circular cross-section. They come in many sizes and have many uses and are are held in a tool called a drill, which rotates them and provides torque and axial force to create the hole13 Drill bits13
14. These finish tools are graded according to the degree of fineness, and according to whether they have single- or double-cut teeth14 Files14
15. A saw consisting of a tough, fine-toothed blade stretched taut in a frame, cuts on the down stroke,used for cutting metal15 Hack saw15
16. For hydraulic powered punching of holes of many sizes and shapes, and for cutting, shearing, notching and bending metal flat bar and angle iron16 Ironworker16
17. To cut sheet metal17 Metal shear17
18. Used to bend metal to make a box or pan18 Box and/or Pan Brake18
19. This type of welding that uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point19 Arc Welder/SMAW19
20. A tool, manual or powered, for turning (driving or removing) screws20 Screwdriver20
