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
4. Cut them out and place them around your class / school.
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!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. 1. Plants and fungi used to be classified together but today, we know their energy metabolism is very different. Plants are ___________ (producers) and make their own food through photosynthesis, while fungi are ___________ (breaking down dead matter for food). | (autotrophs; decomposers. “Heterotrophs” is okay, but decomposers is more specific. Answers must be written in this order to count correctly so they match with the right blanks.) | 2. 2. Plants and fungi are in different kingdoms, but they do have some similarities that caused them to be previously classified together. Both kingdoms of organisms are in the domain __________ and thus are __________ (have a nucleus and organelles). Additionally, both have ______ ______ around the outsides of their cells for extra protection. | (Eukarya; eukaryotic; cell walls. Answers must be written in this order to count correctly so they match with the right blanks.) | 3. 3. Which kingdom is this: decomposers, some species are parasitic, some species are unicellular, some species are multicellular, some species reproduce sexually, some species reproduce asexually? | (fungi) | 4. 4. Which kingdom is this: all species are autotrophs (though some species can occasionally act as heterotrophs), all species are always multicellular, some species reproduce sexually, some species reproduce asexually? | (plants) | 5. 5. How do fungi digest their food? | (external digestion: they secrete digestive enzymes onto their food source and then absorb the nutrients) | 6. 6. Fungi do not have roots. Instead, they have chains of cells called __________. When lots of these cells twist together, they form a structure (usually underground) called a ___________. | (hyphae; mycelium. Hyphae together form a mycelium—not the other way around). | 7. 7. Mold, like the kind that can grow on bread, is an example of which type of fungus? | (threadlike) | 8. 8. Which kind of fungi are truffles and yeast? | (sac fungi) | 9. 9. Mushrooms are a common example of _______ fungi. | (club fungi) | 10. 10. The parasitic fungus that causes athletes foot and the very helpful fungus penicillium (which makes the antibiotic penicillin) are examples of which kind of fungus? | (imperfect fungi) | 11. 11. ________, which can serve as an indicator of air quality, is an alga and a fungus living in a symbiotic relationship on rocks. | (lichen) | 12. 12. Complete the chart below with the different types of reproduction fungi can do (depending on the species and circumstances). | (fragmentation, budding, spores, sexual) | 13. 13. In plants, the process of photosynthesis happens primarily in organelles called _______________. This organelle is full of a pigment called _______________ that helps the photosynthesis reaction. | (organelle: chloroplasts; pigment: chlorophyll) | 14. 14. Write the BALANCED chemical equation for photosynthesis. | (6CO2 + 6H2O + sunlight -> C6H12O6 + 6O2) | 15. 15. In the process of photosynthesis, what materials are the reactants (starting ingredients)? | (carbon dioxide and water, along with sunlight energy) | 16. 16. In the process of photosynthesis, what materials are the products (what is made in the reaction)? | (glucose and oxygen) | 17. 17. Some plants have specialized tube-like structures (called vascular tissue) to help them move materials through their bodies. ____________ is the vascular tissue that moves water from the roots of plants up to the leaves. | (xylem) | 18. 18. Some plants have specialized tube-like structures (called vascular tissue) to help them move materials through their bodies. ____________ is the vascular tissue that moves food (glucose) from the leaves of plants down to the roots. | (phloem) | 19. 19. True or false: Nonvascular plants (like mosses) can grow just as tall as vascular plants (such as trees). Explain your choice. | (False! Having vascular tissue helps move materials throughout a taller organism. It also helps with specializing processes such as photosynthesis or water absorption. Without vascular tissue, plants must have all cells in contact with both the moist ground for water absorption and with sunlight for photosynthesis. Though a nonvascular plant can grow over a large area, it cannot grow tall.) | 20. 20. Plants have a waxy covering called a _________ on the outside of their leaves and stems to prevent them from drying out. | (cuticle) | 21. 21. Fill in the plant classification flowchart. It will work best to copy it onto your answer sheet and fill it in that way. Word bank: angiosperms, vascular, monocots, plants with seeds, dicots, gymnosperms, seedless vascular, nonvascular. | see chart | 22. 22. Mosses and other plants that do not have vascular tissue (nonvascular plants) do not have seeds. Do you think the opposite of this statement is true? Do you think this means that all plants that have vascular tissue (vascular plants) also always have seeds? Explain your answer and give examples. | (This statement is not true. There are plants, called seedless vascular plants, that have vascular tissues such as roots but do not reproduce using seeds. Such plants include ferns and clubmosses and they reproduce using spores.) | 23. 23. Rose bushes, apple trees, and tulips are all examples of flowering plants. They have their seeds inside of fruits or flowers. Another way of saying “flowering plants” is ________________. | (angiosperms) | 24. 24. Pine trees, spruce trees, and other trees sometimes called “evergreens” or “conifers” have their seeds out in the open, meaning they aren’t encased in fruits or flowers. Another name for this kind of plant is ________________. | (gymnosperms) | 25. 25. A tropism is a plant’s response to environmental stimuli. For example, a plant’s roots will sense gravity and always grow down. This is called ________________. A plant’s stem will sense light and grow towards it. This is called _______________. | (gravitropism; phototropism. Answers must be written in this order to count correctly so they match with the right blanks.) |
