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. 1. When the cell membrane allows only certain substances to move across it freely, it can be described asSelectively 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 calledConcentration
7. 7. The two types of cellular transportPassive&Active
8. 8. Two types of passive transport areDiffusion&Osmosis
9. 9. Two examples of active transport areExocytosis&Endocytosis
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 ofOsmosis
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
13. 13. When a cell "eats" or engulfs solids into a vesicle and digests them it is known as__________________Phagocytosis
14. 14. When a cell "drinks" or engulfs liquids into a vesicle and digests them it is known as__________________Pinocytosis
15. 15. When a cell uses energy to expel large amounts of materials out by using a vesicle it is referred to as_______________Exocytosis
