In the lessons

In science the particle model explains solids, liquids and gases: in a solid the particles are packed tightly and vibrate in place; in a liquid they are close but slide past each other; in a gas they are far apart and move fast. When you heat something, its particles move faster. Air pollution and smoke contain particles that are harmful to breathe. Phrases: tiny particles, dust particles, particle of truth.
