QR Challenge: Nuclear Fusion GREEN DAY 2014

Created using the ClassTools QR Treasure Hunt Generator

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

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

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!

Questions / Answers (teacher reference)

Question	Answer
1. 1. Nuclear Fusion turns Hydrogen into Helium.	y
2. 2. Nuclear Fusion releases HUGE amounts of energy.	y
3. 3. Nuclear Fusion requires huge temperatures and pressures in order to work.	y
4. 4. The Hydrogen atoms need to be heated up enough so that they lose their electrons and become ions (see diagram 1).	y
5. 5. The Hydrogen ions are heated up further, to many millions of degrees of Celsius, this causes them to move around faster.	y
6. 6. They are pressurised to squash them as close together as possible.	y
7. 7. When the Hydrogen ions are moving fast enough and are close enough together, instead of bouncing off one another they stick or fuse together.	y
8. 8. We could get all the Hydrogen we ever needed from sea-water.	y
9. 9. The only waste product is Helium, which is inert, non polluting and not dangerous.	y
10. 10. A bath tub full of water contains enough Hydrogen to provide ALL of the energy that a single person would require in 30 years.	y
11. 11. We currently can’t use Nuclear Fusion to produce electricity as we don’t have the required technology to efficiently heat and pressurise sufficient quantities of Hydrogen.	y
