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) The branch of biology that investigates the relationships between different organisms and their environment is called _____________. | (ecology) | 2. 2) The source of energy in all ecosystems is the _____. | (sun) | 3. 3) In a food chain or food web, the arrow points towards the organism that is.... | (eating, doing the consuming, absorbing the energy) | 4. 4) An organism’s “job” or role in the ecosystem (for example: decomposer, scavenger, etc.) is called its ___________. | (niche) | 5. 5) Fill in the blanks on the general food chain below. Word bank: herbivores, decomposers, the sun, carnivores, producers | (see image) | 6. 6) The niche that breaks down dead matter is _______________. | (decomposer) | 7. 7) If an organism eats scraps of dead organisms that it did not hunt for itself, it is known as a(n) ______________. | (scavenger) | 8. 8) In a food chain or web, the organisms that eat plants (and thus get their energy directly from autotrophs) are called herbivores or _______________ consumers. | (primary) | 9. 9) Melody was conducting research on paramecia (which are animal-like protists) in pond water. She observed that the populations would sometimes increase, then level off, then decrease, then eventually increase but generally stayed around the same level overall. Her data resembled the graph pictured below. The dotted line (which shows the population size the paramecia tended towards) represents what concept? | (carrying capacity) | 10. 10) A population cannot grow past a certain size due to limitations in amounts of food, water, air, and living space. Additionally, diseases, natural disasters, and other environmental aspects can keep population growth at a certain level. What is the term given to these factors (food, water, etc.) that limit population growth? | (limiting factors) | 11. 11) When two organisms of different species live in close proximity to each other in a relationship that is helpful, harmful, or neutral for the organisms involved, it is referred to as a _____________ relationship. | (symbiotic) | 12. 12) Organisms that live in a symbiotic relationship of any kind are called ___________. | (symbionts) | 13. 13) Lichen is a symbiotic relationship between blue-green algae (a protist) and a fungus. The fungus helps absorb moisture (which helps the algae) and the algae photosynthesizes to create food for itself and the fungus. What kind of symbiotic relationship exists between these symbionts? | (mutualism) | 14. 14) A female robin makes a nest in the branches of an oak tree. The robin benefits by having a safe shelter for her eggs and the oak tree is not harmed or helped by the robin’s nest. What kind of symbiosis is this? | (commensalism) | 15. 15) Dirofilaria immitis is a roundworm that causes the disease heartworm (common in dogs). They swim through the bloodstream as larvae and mature in the dog’s heart. They absorb nutrients and oxygen from the dog’s blood and can eventually cause congestive heart failure and other organ failure if they are not killed by medicine. Which kind of symbiosis occurs between heartworms and dogs? Explain. | (This is an example of parasitism. In parasitism, one organism (the parasite) benefits while the other organism (the host) is harmed. In this case, the roundworm is the parasite and the dog is the host. The roundworm benefits by absorbing nutrients and oxygen and the dog is harmed because its nutrient and oxygen metabolism is impacted, its blood flow is impaired, and its organs are damaged.) | 16. 16) In a certain forest, wolves hunt rabbits. In this case, the wolves are the _____________ and the rabbits are the ______. | (wolves are predators and the rabbits are prey) | 17. 17) In a certain meadow, many different species depend on being able to eat grass to survive. The deer, rabbits, and insects are in a ______________ relationship to get food. | (competition) | 18. 18) Cornelius was observing bottlenose dolphins as part of his marine biology research fellowship. If he tracks the numbers of only the Tursiops truncatus species in one particular area, he is tracking a(n) _____________. | (population) | 19. 19) Maya was filming a documentary for National Geographic that took her all over the savanna in Sierra Leone. On film, she captured beautiful footage of trees, grasses, zebras, insects, giraffes, elephants, and birds. Together, these different species in a particular area make up a(n) ____________. | (community) | 20. 20) Frank liked a picture from a travel account on Instagram. The picture showed lots of sand, very few trees, and some animals that looked like they were well-adapted to the heat. The caption was “desert vibes.” The photo did not have a specific location tagged, but it had a lot of general characteristics of a desert __________. | (biome) | 21. 21) The area of the planet on which life can exist is called the ____________. | (biosphere) | 22. 22) If we follow one path in the food web below, we see that the zooplankton are the _______ consumers (eating the phytoplankton). Thus, the fish is a ___________ consumer, and the seagull is a __________ consumer. The leopard seal is a ________ consumer and the killer whale is quinary consumer (fifth level)! | (zooplankton: primary or first-level or first-order consumers; fish: secondary or second-level or second-order consumers; seagull: tertiary or third level or third-order consumers; leopard seal: quaternary or fourth-level or fourth-order consumers) | 23. 23) This picture shows an energy pyramid. Explain what happens as you move up the pyramid in terms of ENERGY available and POPULATION SIZE. | (As you move up the energy pyramid, the available energy for the next level decreases. For example, the energy available to the producers is all the energy the sun radiates, but the energy available to the primary consumers is only what is stored in the producers. As you move up the energy pyramid, the populations also decrease. In a healthy ecosystem, there must be plenty of producers to feed the primary consumers, plenty of primary consumers to feed the secondary consumers, and so on.) | 24. 24) Consider the energy pyramid below. Imagine that the phytoplankton (the producers) died off due to a disease. Which population would be immediately in danger? What would eventually happen to the whole ecosystem? Explain. | (Though the crustaceans (the primary consumers) that eat the phytoplankton (the producers) would be the first impacted due to loss of food, eventually the whole ecosystem would collapse. Producers are vital for the health of the ecosystem as they convert sunlight energy into a usable form for the other organisms involved. Without producers, primary consumers would starve, which would cause the secondary consumers to starve, and so on.) | 25. 25) Consider the energy pyramid below. Imagine that the lions (the apex predators) were overhunted. What would happen to the GIRAFFE population? What would happen to the What would happen to the PLANT populations? Explain. | (If the apex predators were killed off, the giraffe population would rapidly increase as there is nothing left to hunt them and keep their numbers low. As the giraffe population increases, the plant population will decrease greatly because there are more giraffes than the ecosystem can support and they are competing for resources, including food.) |
