Classic Chemistry Experiments

This collection of classic chemistry experiments, from the Royal Society of Chemistry, covers a wide range of tried and tested practical work investigations.

These experiments:

* Allow students to apply their knowledge and understanding to what they experience, developing basic skills such as selecting and using equipment, and learning various techniques

* Illustrate a concept or process, offering first-hand experience before further discussion or analysis

* A starting point for investigations, encouraging students to ask questions and make predictions

* Extend the scope of the curriculum and can be done in chemistry or science clubs.

Separating a Sand and Salt Mixture

In this classic experiment, from the Royal Society of Chemistry, students use physical processes to separate a mixture of sand and salt. The soluble salt dissolves and so the mixture can be filtered, leaving the sand in the filter paper.

The resource is set out as teachers' notes followed by the students'...

Viscosity

In this classic experiment, from the Royal Society of Chemistry, students investigate the viscosity of liquids. Different liquids are sealed in tubes with a small air bubble, inverting the tube and timing the rising air bubble allows students to compare viscosity.

Rate of Evaporation

In this classic experiment, from the Royal Society of Chemistry, students investigate factors affecting evaporation. Using propanone on microscope slides, students change the conditions and time how long it takes for the propanone to evaporate. An explanation of a teacher demonstration using data logging apparatus...

Chromatography of Leaves

In this classic experiment, from the Royal Society of chemistry, students use propanone to separate the pigments in a leaf. Chopping up the leaves, and grinding them up with propanone releases the pigments. Propanone is also the solvent used to separate the pigments. The resource is set out as teachers' notes...
