Science Helps Reduce Environmental Impact - 5th Grade Science

Fix leaks. Leaks waste thousands of gallons annually.

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

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

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

Sensor. Sensors measure specific pollutants in real-time.

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

Solar energy. Sunlight can be converted to electricity repeatedly.

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

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

Use less. Excess fertilizer washes into waterways causing harm.

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

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

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

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

Public transit. Shared vehicles reduce total emissions per person.

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

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

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

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