Grouping Materials

Science · Matter & Materials · procedural

Compare and group everyday materials based on their simple physical properties

What mastery looks like

  • Sort a set of materials into groups based on a chosen property (e.g. transparent vs opaque)
  • Compare two materials and state which properties they share and which differ
  • Explain the reasoning behind a grouping decision using property vocabulary

Check your understanding

Can Grouping Materials sort a pile of objects into groups based on their properties, like all the waterproof ones together or all the transparent ones?
