water cycle
What process turns liquid water from rivers and lakes into water vapor that rises into the air?
evaporation
What does "water scarcity" mean in one clear sentence?
lack of enough clean water for people and ecosystem
Name one simple action a student can do at home to conserve water.
turn off faucet while brushing, shorter showers
What does the word "bioeconomy" mean in one simple sentence
economy using biological resources sustainably
Name the process when water vapor cools and becomes tiny droplets that form clouds
condensation
Give one common human activity that increases water scarcity
examples: overuse, pollution, population growth
What is a water-efficient fixture you might find in houses that saves water when flushing the toilet?
low-flow or dual-flush toilets
Give an example of a product made from renewable biological resources
examples: bioplastics, biofuels, bamboo products
What is the term for water moving through plants from roots to leaves and then into the air?
transpiration
Describe one natural cause that can lead to water scarcity in a region
natural cause: drought, climate patterns
Explain how fixing leaks helps conserve water and why small leaks matter over time.
leaks waste gallons over time — fixing saves cumulative water and money
Explain how using plant-based materials instead of fossil fuels can help conserve water or protect water quality.
plant-based materials often require less pollution from extraction and can reduce runoff/pollution compared to petrochemical processes
Explain, in one sentence, how precipitation and runoff help refill groundwater and surface water
precipitation and runoff refill surface and groundwater
Explain how droughts affect both people and ecosystems
drought effects: less drinking water, crop failure, habitat loss, stressed wildlife
Describe a school-wide conservation project students could run to reduce water use
project idea: water-use audit + pledge + signage + monitoring
Describe one way that sustainable farming can support both the bioeconomy and water conservation.
sustainable farming: crop rotation, cover crops, reduced chemical runoff protecting water quality and creating biomass for bioeconomy
Identify and briefly describe the step in the water cycle where water soaks into the soil and becomes part of underground aquifers.
infiltration into aquifers.
Provide two ways that cities can change their water systems to reduce the risk of scarcity
city changes: reduce leaks, improve recycling/reuse, use efficient irrigation, diversify water sources.
Compare and explain the difference between "water conservation" and "water reuse" with one example of each.
conservation = using less water (shorter showers), reuse = treating and using water again (greywater for irrigation).
Imagine a small community using bio-based solutions to reduce pollution and save water; list three connected actions they could take and why each helps
community actions: create wetlands to filter water, switch to bio-based cleaning products, composting to reduce waste — each reduces pollution, improves soil, or reduces water treatment needs.
