  1. 1From Harvested Stalks to Clean GrainFollow a harvest to see why handpicking, threshing, and winnowing solve different separation problems.
  2. 2Sorting Solids by Size and MagnetismCompare sieves and magnets as ways to sort solid mixtures by different properties.
  3. 3Recovering a Dissolved SolidUse evaporation to understand why water can leave a salt solution while salt remains.
  4. 4Settling and Pouring Off MixturesLearn when gravity can settle material and when careful pouring can separate layers.
  5. 5Filtering Liquids and Designing a FilterFollow tea and muddy water through different porous materials, then plan a useful filter.
  6. 6Choosing and Combining Separation MethodsUse churning and a property-first decision process to solve mixtures with many components.
  7. 7Summary & PracticeConnect every method to the property it uses and solve everyday separation problems step by step.
