The 20 questions

  1. What is a mangrove?

    • A salt-tolerant tree that grows where the land meets the sea
    • A type of coral that grows in deep, dark water
    • A desert plant that stores water in its thick stem
    • A cold-loving shrub that grows on polar ice and survives under deep snow all winter long

  2. What does synoptic mean in this enquiry?

    • Measuring the same thing many times over to check that the instrument is working properly
    • Bringing many ideas from the unit together to answer one big question
    • Answering a question using only one single source
    • Looking at one small place in great detail

  3. What is a stakeholder?

    • A tourist who pays to visit a protected area
    • A scientist who records data for a government
    • A person or group who is affected by a decision
    • A person who owns a shop and sells goods to customers

  4. What is a trade-off?

    • When gaining one thing means giving up another
    • A price that is lower for buyers than for sellers
    • A deal that gives equal gains to every person
    • A loan repaid with interest over many years

  5. What does justify mean when making a case?

    • Measuring the size of a habitat with a tape measure and recording the answer in a table
    • Describing every feature of a place in full detail
    • Listing the names of all the animals in a biome
    • Giving clear reasons that show why your choice is a good one

  6. What do mangrove roots provide for baby fish?

    • Shelter from predators in a safe nursery
    • Warmer water that speeds up their growth
    • Salt that is pumped out of the sea water
    • Soft mud that turns into rich farmland

  7. What is one way mangroves help protect people on tropical coasts?

    • They produce oil that is used in cars
    • They stop all rain from falling on nearby villages
    • They make the sea water warmer for swimmers
    • They shield coasts from storm waves

  8. Which activity is a common reason mangroves are cleared?

    • Making way for shrimp farms
    • Creating ski slopes on the coastline
    • Building large solar farms in the desert
    • Growing cactus for export to other countries

  9. A government can protect one ecosystem. Which pair of reasons is strongest for choosing a mangrove coast?

    • It has a very pretty view that tourists enjoy
    • It is close to the capital and easy to reach
    • It receives a lot of rain each year, so the land is wet and covered with thick forest
    • It is a habitat for many species and it protects villages from storms

  10. A plan includes the action 'replant mangroves'. Which benefit is for wildlife?

    • The villages are moved to inland towns, where the new homes are built far from the coast
    • New roots shelter baby fish, so fish numbers can recover
    • The coast is cleared to build new hotels
    • Shrimp farm owners earn more money from new land

  11. A plan includes the action 'pay local fishers as guards'. Which benefit is for people?

    • Storm waves become larger because the trees are guarded
    • Shrimp farmers are given free use of the mangroves
    • Fishers are moved away from the coast for good, so the fish stocks can recover slowly
    • Fishers earn wages, so they have a reason to protect the trees

  12. Which is a cost of replanting mangroves?

    • It takes years for the new trees to grow and rebuild the habitat
    • It makes storms stronger because the roots trap water
    • It stops all fish from living in the sea
    • It forces every village to move inland, so the coast is left completely empty of people

  13. Which stakeholder is most likely to want the mangroves cleared?

    • A fisher whose catch is shrinking
    • A villager flooded in the last storm
    • A scientist studying rare birds
    • A company building a shrimp farm

  14. A plan bans shrimp farms in the worst-hit area. What is the main trade-off?

    • Wildlife loses its homes, but farmers gain more land for crops
    • Wildlife is protected, but some farmers lose income from their land
    • Tourism falls, but the mangroves grow faster and provide shade for many new tourists
    • Storms become stronger, but fishers earn more money

  15. A pupil says 'the mangrove is pretty, so we must save it.' Which change would make this reason stronger?

    • Say that everyone loves mangroves, so the government must agree
    • Add evidence of what it does for fish and for people, such as shelter and storm protection
    • Repeat the claim more loudly in every sentence, so that the reader cannot ignore it or question it at all
    • Say it is pretty again and add more adjectives about its colour

  16. Which statement shows a justified plan?

    • We should build a hotel on this coast because it will make money fast for the town, bring many tourists, and create lots of jobs for the town's families
    • We should clear the trees because the land is flat and empty
    • We should protect the coast because it is important and must be saved
    • We should protect this mangrove coast because it shelters fish and protects villages, so the plan helps wildlife and people

  17. Which is the best synoptic response to a two-action plan?

    • It links each action to wildlife and people, weighs a benefit against a cost, and gives a clear overall reason
    • It describes the coast in detail but makes no decision, and it lists facts about the coast without any reasons for them, so it is only a description
    • It repeats one benefit three times to make it sound strong
    • It lists two actions and stops there, without any reasons

  18. Why must a good protection plan consider several stakeholders?

    • Only scientists need to be consulted, because they know all the facts
    • A plan only needs one stakeholder to succeed, because the strongest group always decides every outcome for everyone involved
    • Stakeholders only care about money, so their views can be ignored
    • Plans that ignore local people or businesses often fail, because those affected may resist them

  19. Which reason best justifies protecting a mangrove coast rather than clearing it for farms?

    • Farms need more fresh water than mangroves ever use, and farms always make more money for the local coast
    • Mangroves are only useful for the first few years after planting
    • Mangroves shelter fish and protect the coast from storms, keeping wildlife and people safer over time
    • Mangroves grow faster than any crop, so they feed people sooner

  20. Which statement best shows a trade-off in a plan to protect mangroves?

    • Protecting the trees keeps fish and the coast safe, but may limit land for farming or building
    • Protecting the trees gives farmers more land and no costs at all, so everyone agrees the plan is perfect
    • Protecting the trees makes storms more dangerous for villages
    • Protecting the trees costs nothing and gives everyone a benefit
