Lesson Plan: Filtration and Crystallization Chemistry

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to separate mixtures using filtration and crystallization, decide the apparatus needed, and determine when each should be used.


Students will be able to

  • describe and explain how filtration can be used as a separation and purification method,
  • describe and explain how crystallization can be used as a separation method,
  • identify crystallization and filtration labware and apparatus from descriptions and illustrations,
  • describe and explain how crystals can be obtained from evaporating all the solvent,
  • describe the key steps in performing filtration or crystallization,
  • identify the best methods for performing particular separations,
  • identify which purification and separation method would be best for a given mixture or experiment,
  • identify problems, errors, and potential hazards that may occur during filtration or crystallization.


Students should already be familiar with

  • solutions,
  • scientific equipment,
  • solubility.


Students will not cover

  • distillation,
  • forms of filtration such as ultrafiltration or microfiltration,
  • recrystallization.
