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!

Questions / Answers (teacher reference)

Question

Answer

1. What is the definition of light absorption?When light is taken in.
2. What is the definition of accessory pigments?Reflect colors of light other than green.
3. What is the definition of chlorophyll?Most of the light energy that plants absorb is absorbed by this pigment.
4. What is the definition of a pigment?Absorbs many colors of light and reflects one color of light; chlorophyll is an example.
5. What is the definition of reflection of light? When light bounces back.
6. What is the definition of the visible spectrum? All of the light that humans can see; includes all the colors of the rainbow.
7. What is the structure of upper leaf cells (what are they physically made of)? Packed together very tightly, and have many chloroplasts.
8. What is the structure of lower leaf cells (what are they physically made of)?Packed together very loosely, and have space between them like a sponge.
9. What is the structure of stomata (what are they physically made of)?Pores (holes).
10. What is the structure of guard cells (what are they physically made of)?Sausage-shaped cells that surround the holes.
11. What is the structure of xylem (what are they physically made of)?Tubes.
12. What is the structure of phloem (what are they physically made of)?Tubes.
13. What is the structure of cuticles (what are they physically made of)?waxy, waterproof layer.
14. What is the function of cuticles (what they do)? Keeps water inside of the leaf.
15. What is the function of guard cells (what they do)? Open and close the stomata.
16. What is the function of lower leaf cells (what they do)? Let carbon dioxide and oxygen move around in spaces inside of the leaf.
17. What is the function of phloem (what it does)?Transports food.
18. What is the function of xylem (what it does)?Transports water.
19. What is the function of stomata (what they do)? Let carbon dioxide in, and lets oxygen and water vapor out.
20. What is the function of upper leaf cells (what they do)? Absorbs lots of light energy, and do most of the photosynthesis.
21. Are more stomata usually OPEN during the day or during the night? Why?During the day, so that photosynthesis can take place.
22. What are the 2 reactants (inputs) of photosynthesis?Carbon Dioxide and Water.
23. What gives the energy for photosynthesis to happen?Light Energy.
24. What are the 2 products (outputs) of photosynthesis?Sugar and Oxygen.
25. How do chloroplasts help make photosynthesis happen? They absorb light to get energy for photosynthesis.
26. How do vacuoles help make photosynthesis happen? They store water for photosynthesis, and store the food that is made in photosynthesis.
27. How do vacuoles help make photosynthesis happen? They make the plant rigid (stiff) so that the leaves can be held up to absorb light.
28. What is the carbon dioxide—oxygen cycle?Plants take in carbon dioxide for photosynthesis, and give off oxygen; animals take in oxygen and give off carbon dioxide. The process is ongoing.
29. Why do leaves look green?Chlorophyll is the major pigment in leaves. Chlorophyll mainly absorbs red and blue light, and reflects green light. We see leaves as green because the green light reflects into our eyes. Accessory pigments are pigments that are different colors than chlorophyll. Accessory pigments are usually not seen in leaves because chlorophyll covers them up.
