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. The earliest commercial movies were called silent movies. Most silent moves were projected using a film speed of one foot per second. How many frames per second were displayed in a silent movie?16 frames per second.
2. When sound was introduced in 1929, the motion picture frame rate was increased to 24 frames per second. The same rate is still used in movies today. How fast does the film move at this rate, in feet per second?1.5 ft/sec or 1 1/2 ft per sec.
3. The movie Toy Story 2 runs for 92 minutes. How long is the projector film for this movie? 8280 feet
4. How many frames were in the movie Toy Story 2?132,480 frames.
5. In a live action movie, only a small fraction of the film that is shot makes it into the final movie. Each scene may be shot several times (“Scene 6, take 3!”), and only portions of each shot are used. Suppose only 1/20th of the film that is shot is eventually used to make Toy Story 2. How much film must be purchased to shoot the movie?You would need at least 165,600 feet of film.
6. If a 400 foot roll of camera film cost $220 and developing costs $0.20 per foot, how much money did it cost for the filming and developing of Toy Story 2?124,200
