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. Name one of the principles of the Cell Theory	Cells come from pre-exsisting cells and cannot be created from non-living material
2.
3. What is the function of the pilli in Prokaryotic cells	The pilli helps the cell in adhesion and in exchanging genetic material.
4.
5. State one difference between animal and plant cells	Animal cells do not usually contain any vacuoles and if present they are small or temporary. On the other hand plants have a large vacuole that is always present.
6.
7. What is the cell membrane of Eukaryotic cells made of?	Phospholipid molecules make up the cell membrane and are hydrophilic (attracted to water) as well as hydrophobic (not attracted to water). They have a hydrophilic phosphate head and two hydrophobic hydrocarbon tails.
8.
9. Describe the events that occur during Anaphase?	During anaphase the spindle microtubules pull the sister chromatids apart splitting the centromeres. This splits the sister chromatids into chromosomes. Each identical chromosome is pulled to opposite poles.
10.
11. What is the purpose of the nucleoid region in Prokarotic cells?	It is the region containing DNA which stores the hereditary material (genetic information) that controls the cell and will be passed on to daughter cells.
12.
13. State the definition of binary fussion?	Binary fission is a method of asexual reproduction involving the splitting of the parent organism into two separate organisms.
14.
15. State the function of golgi apparatus?	It receives proteins from the rough endoplasmic reticulum and may further modify them. It also packages proteins before the protein is sent to it’s final.
16.
17. What is one of the differences of Prokaryotic cells and Eukaryotic cells?	In prokaryotes there are either no or very few organelles bounded by a single membrane whereas in eukaryotes which have many of them including the Golgi apparatus and the endoplasmic reticulum.
18.
19. What are two ways molecues are transferred in and out of the cell?	Diffusion and Osmosis
