Principle

This experiment to be performed by students themselves, demonstrates how a mixture of salt and sand can be separated into its components. This involves adding some water to a mixture of solid salt and solid sand to make a suspension which is then poured through a filter paper. The sand will remain in the filter while the salt will dissolve into a solution which passes through the filter into a beaker underneath.

Benefits

  • Experiment guides are very easy to understand, especially for younger students
  • Associated competences are directly linked to the experiments
  • Curriculum compatible
  • Fit for the future: implementation of tablets possible
