QR Challenge: Safety Science Scenario

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. Scenario #1 The teacher was not in the room yet. Jake began weighing chemicals and touching them with his hands. His nose itched, so he rubbed it.	Never work alone in the laboratory. Never Perform activities that are not authorized by your teacher.
2. Scenario #2 Heather and Jennifer were absent the day before when the investigation was discussed. They gathered the materials and watched their classmates to see what to do, not taking the time to read the directions.	Read all directions for an investigation several times.

3. Scenario #3 Sam was heating a test tube. He didn't put on safety goggles since he was wearing glasses. He slanted the tube away from his work area, but toward students on the opposite side of the table.	His behavior was unsafe, because glasses do not protect the side of your eyes, and he could still get fumes or particles in his eyes. Also, a student should never point the open end of a test tube toward anyone. If it boils over or spills, it could injure a classmate.
4. Scenario #4 Cindy broke a test tube. Carefully she picked up pieces with one hand and placed them in her other hand. Then she dumped the glass pieces into the wastebasket.	Cindy should have notified the teacher immediately, and the glass should go in the glass disposal.

Make sure you start cleaning up when the teacher instructs you to do so. Always completely clean your lab station before you leave class.
8. Scenario #8 Gina didn’t pay attention when the teacher explained where safety equipment was found and how it was used. She thought to herself, “I’ll never need that.”	Gina's behavior is unsafe,because everyone should be aware of where the safety equipment is, in case an accident happens.
9. Scenario #9 Martha is thirsty. She rinses a beaker with water, refills it with water, and takes a drink.	There can be chemicals left over in a beaker, or on lab tables that can be harmful if ingested. You should never eat in a lab, and should never taste anything in a lab.
