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.

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. 399 BC. That’s 2018+399= 2,417 years ago. You start learning addition in Kindergarten. | Do you know the year of the first catapult? |

2. Velocity is how fast something moves. To figure it out you’ll need multiplication which you learn in 3rd Grade. | What is Velocity? A city? A bird? Math? |

3. Yes you have. It’s known as DNA and it’s what carries genetic information, making you, You! | Have you ever had deoxyribonucleic acid? |

4. Probability is how likely something is to happen or not happen. You’ll learn this in 6th grade using the multiplication you learned already. | Which of these will you use to study genetics? Probability? Macaroni? |

5. Charles Darwin wrote the Origin of Species in 1859. | Who wrote about Natural Selection? Charles Dickens? Charles Darwin? |

6. They should land at the same time. Gravity pulls all objects at the same rate. Wind resistance can change this. | If you drop a bowling ball and a marble from a tall building at the same time, which will land first? |

7. 9.81 meters per second per second. You start to learn about meters in 2nd Grade | Do you know how fast those two things are falling? |

8. They both weigh a pound. You’ll learn about weight in Kindergarten and Pre-Kindergarten. | Which weighs more, a pound of pennies or a pound of feathers? |

9. 145 pennies. That’s $1.45. You’ll learn about money in 1st Grade. | How many pennies are in a pound? |

10. Angles. Angles are measure in degrees. 180 degrees is a straight line. You start learning about angles in 2nd Grad | To build a bridge, an engineer must know about Angles? Apples? |

11. A camel is slowest at 30 beats per minute. A bat is the fastest at 750 b.p.m. | Whose resting heart rate is lower: human, camel, or bat? |

12. This equation tells you how much fluid is travelling. V is the volume, or amount of fluid. T is the time it took. You will start learning about division in 3rd grade. | What are these letters telling me? Q = V/T |

13. Slime was first sold by Mattel in 1976. | When was slime first sold? 1976? 1986? 2016? |

14. A ratio shows a relation between numbers. A typical slime recipe is 1 oz glue: 0.25 cups water: 0.25 Borax. You could convert that to whole numbers as 4:1:1. You will learn about ratios in 6th Grade | To mix slime you need to use a circumference? a ratio? a meter? |

15. Light moves at 186, 000 miles every second. You would be able to go around the Earth 7 times. | If you could travel at the speed of light, in 1 second you would make it to Boston, England, around the world? |

16. Angles are often measured in degrees. A straight line is 180 degrees and a circle is 360 degrees. You will start to learn about special angles in 5th grade. | The angles you measure to direct light are measured in degrees, feet, grams? |

17. Hans Lipershey was a Dutch eyeglass maker who applied for the first patent but several other stories exist of earlier inventions. Galileo Galilei heard of the invention, improved it, and used it to look at the stars. | The inventor of the telescope was named Galileo, Hans, Unknown? |

18. To determine the magnification (power) of a telescope you divide the length of the telescope by the eyepiece diameter. You’ll learn about diameter in 6th Grade | How do you know the strength of your telescope?. |

19. Degrees. In all of these areas they need to measure angles in degrees. You learn about degrees in 4th grade | Did you visit the Plants or Telescope station? If you did, you may have heard this word for measurement that is also used with filming on a green screen. What is it? |

20. 1930 and the screen was blue. The movie was The Thief of Baghdad. | In what year did the Green/Blue Screen get used in a movie? 1930, 1960, 1980? |

21. Yes! Those are the same lengths. One is in metric and the other US Customary. You’ll learn about that in 2nd Grade. | An unraveled silkworm cocoon can produce how much thread? 100-300 meters or 325-925 feet? |

22. 6-8 weeks. That’s’ 42-56 days or a month and a half to two months. You will start learning time duration in 2-4th Grades | The life cycle of the silkworm is 6-8 days? 6-8 weeks? 6-8 months? |

23. The full Genome (DNA information) was printed in 2008. The silkworm has 28 chromosomes. | Did you visit the Gene (DNA) exhibit here tonight? If so, here’s a fact. |
