How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Which option is a renewable energy technology: solar panels, coal furnace, or gasoline engine?

Answer: Solar panels. They convert sunlight directly into electricity without pollution.

Flashcard 2: Identify the best action to save water at home: fix leaks or leave a tap dripping?

Answer: Fix leaks. Leaks waste thousands of gallons annually.

Flashcard 3: What does energy efficiency mean for community buildings and devices?

Answer: Using less energy to do the same job. Reduces waste and saves resources.

Flashcard 4: What is the main purpose of a water treatment plant in a community?

Answer: Remove pollutants so water is safer for people and ecosystems. Filters and chemicals clean water before distribution.

Flashcard 5: Which option best shows science guiding decisions: collect data first or guess first?

Answer: Collect data first. Evidence-based decisions are more effective than assumptions.

Flashcard 6: Which option is a science tool communities use to track air quality: thermometer or sensor?

Answer: Sensor. Sensors measure specific pollutants in real-time.

Flashcard 7: Which option best describes why planting trees can reduce environmental impact?

Answer: Trees absorb $CO_2$, reduce erosion, and improve air quality. Trees provide multiple environmental benefits.

Flashcard 8: What is an example of a renewable energy resource a community can use?

Answer: Solar energy. Sunlight can be converted to electricity repeatedly.

Flashcard 9: What is an example of a nonrenewable energy resource?

Answer: Coal. Forms over millions of years and can't be replaced quickly.

Flashcard 10: What is the main environmental benefit of reducing waste sent to landfills?

Answer: Less land pollution and less methane released from decomposing trash. Landfills produce harmful gases and contaminate soil.

Flashcard 11: Identify the best choice to reduce fertilizer pollution in local streams: use more or use less?

Answer: Use less. Excess fertilizer washes into waterways causing harm.

Flashcard 12: Which option is the best science-based reason to use public transportation?

Answer: It reduces fuel use and air pollution per person. Shared vehicles mean fewer total emissions.

Flashcard 13: What is the key science idea behind using LED light bulbs to reduce impact?

Answer: They use less electrical energy for the same brightness. LEDs convert more electricity to light, less to heat.

Flashcard 14: Which action most improves energy efficiency at home: LED bulbs or leaving lights on?

Answer: Using LED bulbs. LEDs use 75% less energy than traditional bulbs.

Flashcard 15: What is the greenhouse effect?

Answer: Heat trapped by gases in the atmosphere that warm Earth. Natural process that keeps Earth habitable.

Flashcard 16: Which community choice reduces greenhouse gas emissions most: public transit or more single-car trips?

Answer: Public transit. Shared vehicles reduce total emissions per person.

Flashcard 17: What is recycling?

Answer: Processing used materials to make new products. Reduces landfill waste and saves raw materials.

Flashcard 18: What is composting?

Answer: Breaking down food and yard waste into nutrient-rich soil material. Natural decomposition creates fertilizer.

Flashcard 19: Which waste item is best for composting: banana peel or glass bottle?

Answer: Banana peel. Organic matter decomposes; glass doesn't.

Flashcard 20: What is an ecosystem?

Answer: A system of living things interacting with each other and their environment. All parts depend on each other for survival.

Flashcard 21: What is habitat restoration as a community environmental solution?

Answer: Repairing damaged habitats to support native plants and animals. Rebuilds natural homes for wildlife.

Flashcard 22: Which practice reduces soil erosion most: planting ground cover or leaving soil bare?

Answer: Planting ground cover. Plant roots hold soil in place.

Flashcard 23: What is a watershed?

Answer: Land area where all water drains to the same river, lake, or ocean. Shows how water connects different areas.

Flashcard 24: What is the scientific purpose of monitoring air or water quality in a community?

Answer: To measure pollution levels and guide solutions and policies. Data helps identify problems and track improvements.

Flashcard 25: What is environmental impact in a community science context?

Answer: The effect of human activities on air, water, land, and living things. Focuses on how people change their surroundings.

Flashcard 26: What is the main goal of sustainability for a community?

Answer: Meet needs now while protecting resources for the future. Balances current use with future availability.

Flashcard 27: What is conservation as a science-based community action?

Answer: Using natural resources wisely to prevent waste and damage. Protects resources through careful use.

Flashcard 28: What is pollution?

Answer: Harmful substances added to air, water, or soil. Contaminates natural environments.

Flashcard 29: Which option is a renewable energy source: coal, wind, or gasoline?

Answer: Wind. Can be naturally replenished, unlike fossil fuels.

Flashcard 30: What science idea explains why solar panels can reduce air pollution?

Answer: They generate electricity without burning fossil fuels. Clean energy avoids combustion emissions.
