FOSS Third Edition Mixtures and Solutions Complete Kit

Grades 4 - 6


Chemistry is the study of the structure of matter and the changes or transformations that take place within those structures. The Mixtures and Solutions Module introduces students to the properties and behaviors of substances and changes in substances–fundamental ideas in chemistry.

Students will:

  • Make and separate mixtures, using screens, filters, and evaporation.
  • Measure solids and liquids to compare the mass of a mixture to the mass of its parts.
  • Use a balance to determine relative concentration. Layer solutions to determine relative density (concentration).
  • Plan and conduct saturation investigations.
  • Compare the solubility of substances in water.
  • Identify an unknown substance based on the properties of solubility and crystal form.
  • Observe and compare reactants and products of several chemical reactions.


  • Investigation 1: Separating Mixtures
