household dirt

A young boy mops, sweeps, and dusts until his room meets with his mother's approval, but there is still a spot far under his bed that the dust bunnies grow.

Describes distasteful things that can be found in houses, such as dust mites, dander, germs, and mold.

Presents full-color illustrated drawings that describes what dust is, the different kinds of dust such as pollen, house dust, dirt from the farmer's plow, dust storms, fires, and ash from volcanoes.

Using scanning electron microscopy, studies household dirt, dust, and germs, and the substances that are used to get rid of them.
