Measuring Air Quality Improvements from Vegetative Barriers.

Vegetative barriers, which include trees and bushes, can help reduce pollution near busy highways and roads. As part of EPA's research on this topic, K-5 lesson plans and activities have been developed that focus on air quality, air sensors, air pollution, and the impact of air pollution on human health. Each lesson contains an in-class activity as well as a field experience activity which requires the use of stationary and/or mobile sensors.
