Use cobalt chloride as a humidity detector to predict the possibility of rain
Read moreHumidity 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...

Test and compare the protein content in various everyday foods
Read moreMeat 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.

Use red cabbage as an indicator to test if a substance is an acid or base
Read moreAcids 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...

Use chromatography to predict the ‘fall’ colour of a green leaf tree
Read moreIn 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,...

Use iodine to test for the presence of starch in foods
Read moreWhen 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...

Study how temperature affect the stretch of an elastic band
Read more'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...

Extract the starch from raw potatoes and break it up into sugar
Read moreWhen 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...

Drawing colours from black ink using basic ‘chromatography’
Read moreVarious 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...

Make your own stalactites
Read moreStalactites 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.

Learn why some liquids do not mix with each other
Read moreNot 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...
