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. Cell - The most basic unit of life. Smallest unit that can perform functions of life.
2. Cell Wall - A protective layer (made of cellulose) that surrounds the cell.
3. Plasma Membrane - The thin sheet that holds the contents of the cell together and serves as a protective barrier from the surrounding environment.
4. Cytoplasm - The living semi-fluid material inside the cell membrane.
5. Organelles - Small structures inside the cell that carry out physiological processes.
6. Plastids - Organelles that produce and store food.
7. Chloroplasts - Type of plastid that contains green pigments called chlorophyll.
8. Chlorophyll - Traps light energy for photosynthesis. Found in cells exposed to light, abundant in leaves.
9. Ribosomes - Bead-like structures found on the endoplasmic reticulum. Major site for the assembly of amino acids into proteins.
10. E.R. Smooth - The site for the production of lipids (fats) and hormones. Also breaks down toxic chemicals.
11. E.R. Rough - Produces proteins for the cell secretion and cell membranes.
12. Golgi Bodies - Proteins are processed, sorted and modified. These processes result in the complex molecules needed for plant growth.
13. Mitochondria - Converts sugar into energy through cellular respiration. Able to convert the food that it has made and stored into a form of energy.
14. Nucleus - The command center of the cell. Holds the genetic information for a cells activity within a nuclear membrane.
15. Nucleolus - Specialized structure in a nucleus that is the site of ribosome synthesis.
16. Chromosome - Holds the genetic blueprint of the organism and direct all functions of the cell, including protein synthesis.
17. Middle Lamella - A thin cementing layer that holds together plant cells.
18. Vacuole - Large sac bound by a membrane that may occupy up to 90% of the cell. It serves to transport and store water, foods, salts, minerals, pigments, proteins and wastes.
