Chemical Analysis

Humidity is often seen as an indication of the likelihood of rain occurring, and this is usually measured with a 'hygrometer'. A chemical humidity detector or 'hygrometer' can be made by dipping a piece of paper or cloth in...

Meat and dairy products are foods which are rich in protein. In this science experiment, test for proteins in some everyday foods to see which have the highest content.

Acids and bases are opposites and cancel each other out or 'neutralizes' when mixed together. 'Litmus' paper is an 'indicator' and turns red when mixed with an acid or blue when mixed with a base. In the following science...

In a process called 'chromatography', scientists can separate the individual parts of a mixture so that each one can be identified separately. In the following science experiment, use 'chromatography' to analyse which other 'pigments' are present in green leafs,...

When starch is combined with hot water it breaks up into a kind of starch/sugar molecule called 'dextrin'. When the 'dextrin' is heated further, it breaks up into even finer sugar molecules called 'maltose'. In this science experiment you...

'Polymers' are compounds made of very long chains of molecules which often have 'plastic' or 'rubber' properties. An elastic band is made up of long polymer chains giving it its elastic properties. In this science experiment you will...

When starch is combined with hot water, it breaks up into a kind of sugar molecule called 'dextrin'. When the 'dextrin' is heated further, it breaks up into even smaller sugar molecules called 'maltose'. In this science experiment...

Various colours of ink can be mixed together to form new ink colours and this is often used to obtain a specific colour for ink bottles, calligraphy pens and felt tipped pens. In the following experiment you will see...

Stalactites form on the roof of a cave, whereas stalagmites form on the floor. When the water drips, it 'evaporates' and leaves the dissolved minerals behind, as you will see in the following science experiment.

Not all liquids can be mixed together to form one new liquid substance. If more than one liquid cannot be mixed together it is called 'immiscible' liquids. In this science experiment we will investigate the strange behaviour of some...
