QR Challenge: Biology Midterm Review QR Scavenger Hunt
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!
C. TIPS / OTHER IDEAS

Questions / Answers (teacher reference)
Question | Answer |
| 1. 1. When the cell membrane allows only certain substances to move across it freely, it can be described as | Selectively Permeable
|
2. 2. The transport of materials across a membrane that requires energy? | Active Transport
| 3. 3. The cell membrane is made of phospholipids with a ___________ phosphate head and 2 ________________ fatty acid chain "tails. | Hydrophilic&Hydrophobic
| 4. 4. What type of transport requires extra energy (ATP) to be used to bring materials into the cell or expel materials out of the cell moving from low concentration to high concentration AGAINST the concentration gradient? | ActiveTransport
| 5. 5. What type of transport requires no extra energy by the cell because molecules move from high concentration to low concentration areas DOWN the concentration gradient? | PassiveTransport
| 6. 6. The number of molecules of a substance in a given volume is called | Concentration
| 7. 7. The two types of cellular transport | Passive&Active
| 8. 8. Two types of passive transport are | Diffusion&Osmosis

| 10. 10. A raisin is placed in a cup of water overnight, by the morning the raisin swells to twice its original size. This is an example of | Osmosis
| 11. 11. What do you call a solution in which the water concentration is below what is found in a cell's cytoplasm? (HINT: What is the concentration inside the cell) | Hypertonic
| 12. 12. What do you call a solution in which the water concentration is above what is found in a cell's cytoplasm? (HINT: What is the concentration inside the cell) | Hypotonic
