How dirty is the air near you? Is it better inside or outside? For this experiment homemade monitors measure air for a week. Though most pollution is invisible this experiment can indicate air quality. Pollution levels are a key part of the climate change issue. NPL is involved in air quality measurements: particulates both visible (which this experiment detects), and invisible, plus gas emissions including greenhouse gases.
