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. A horizontal line on a distance- time graph means an object is ... STATIONARY
2. The gradient of a distance-time graph shows how _____ something is moving. QUICKLY
3. A horizontal line on a speed- time graph means an object is ... CONSTANT SPEED
4. Acceleration = change in speed/ ? TIME TAKEN
5. Rearrange this equation to show how we would calculate the change in speed. CHANGE IN SPEED = FINAL SPEED – INITIAL SPEED
6. What is the name given to the distance travelled between putting your foot on the brake and the car stopping? PHYSICAL BRAKING DISTANCE
7. Why does the thinking distance increase with speed? STRESS INCREASES
8. Why does drinking alcohol cause the thinking distance to increase? REACTION TIME IS LONGER
9. Work done = ? x force DISTANCE
10. What is the name given to the units we use to measure work? JOULES
11. Car A runs at 5 miles per gallon; car B at 12 miles per gallon. Which has the best fuel consumption? CAR B
12. Why does running an electric car often still require burning of fossil fuels? COAL POWER STATIONS
13. What is the name given to movement energy? KINETIC ENERGY
14. Which two factors affect the amount of this energy? SPEED AND MASS
15. What is an active safety features? ANTIBRAKE LOCK SYSTEM
16. What is a passive safety features?. SEAT BELT AND AIRBAGS
17. What is the function of a crumple zone? DRIVER FEELS LESS IMPACT FORCE
18. Name two forces acting on a falling parachute. DOWNWARD WEIGHT AND UPWARD AIR FRICTION
19. What is the name of the speed at which these forces are balanced and the speed will remain constant? TERMINAL VELOCITY
20. Give one thing car manufacturers can do to reduce drag. REAR SPOILER/LOWER PROFILE
21. What is the name of the type of energy an object held above the ground will have? GRAVIATIONAL POTENTIAL ENERGY
22. What affects this energy? MASS AND HEIGHT AND GRAVITY
23. When a coaster car rolls downwards, this energy is changed to what sort of energy? KINETIC ENERGY
