QR Challenge: Cells and Epithelial Cells

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. What does the term cell mean	the fundamental microscopic unit that makes up all living matter
2. In what year did Robert Hooke write his book Micrographia	1665
3. In 1839 cell theory was proposed and the idea was supported by the work of which two scientists	Schleiden and Schwann
4. The original cell theory has been modified because of the development of which techniques and theories	electron microscopes, evolutionary theory and genetics
5. write a modern definition of cell theory	cells arise only by the division of existing cells. Cells are able to divide to form new cells. Cells contain inherited information which controls their activities. Metabolism takes place in cells, given suitable conditions cells are capable of independent existance.
6. What are the challenges facing cells in a multicellular organism	coordination and communication
7. Describe the role of tissues and organs in an organism	A tissue is a group of similar cells and the intercellular substances associated with them that work together to carry out one or more functions in an organism. Organs are multicellular structures composed of different tissues adapted to carry out one or more functions
8. Where are epithelial cells found	Lining the walls of cavities such as the gut
