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.
- 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
