Matter Is Made of Particles

Science · Matter & Materials · conceptual

Develop a model to describe that matter is made of particles too small to be seen, and that this explains properties of solids, liquids, and gases

Sign in to track this

What mastery looks like

  • Describe matter as made of particles too small to see with the naked eye
  • Use a particle model to explain differences: particles tightly packed (solid), loosely arranged (liquid), spread far apart (gas)
  • Use the particle model to explain a state change (e.g. heating makes particles move faster and spread apart)

Check your understanding

Can Matter Is Made of Particles explain that everything is made of tiny particles we can't see, and that how tightly packed they are determines whether something is a solid, liquid, or gas?
