  • Propel a small ‘boat’ with magnetic power

    You can have a lot of fun by making a 'sail' boat that is invisibly driven by magnetic power. In this science experiment we will be making a boat that can 'sail' even when there is no wind power!

  • Use a solar powered calculator to measure light levels

    In the following science experiment, use the solar cell on a solar powered calculator as a light-measuring device to test if two 60W bulbs emit the same amount of light as one 120W bulb.

  • Remove the tarnish off silverware using an electrolyte

    In a process called 'electroplating' it is also possible to reverse the process and 'add' electrons to a metal by taking the electrons from a more 'active' metal such a copper and fusing them to a metal such as...

  • Make a spring balance to compare the weight of various objects

    'Gravity' is the force with which the earth attracts bodies near its surface. All objects have weight because the earth's gravitational force pulls on them. The greater the pull of gravity on an object, the more it weighs. In...

  • Make a see-saw candle

    Two identical objects can be 'balanced' when suspended from a horizontal beam at an equal distance from a centre pivot point or 'fulcrum', because the gravitational force acting on each object is the same. If one of the...

  • Learn about the speed of various falling objects

    Gravity can be explained as the force with which the earth attracts bodies near its surface. Gravity causes a falling object to hit the ground with a thud. The greater the height from which an object falls, the bigger...

  • Test if marble is present in rock samples

    When unpolished marble is found in the rough, most people will confuse it with just any other metamorphic rock. Geologists often make use of various lab tests to test for the presence of specific substances in rocks. Similarly, in...

  • Measure the height of your school with the use of the sun

    Think of some ways to measure the height of your school building with relative accuracy and ask some of your friends to help. This science experiment is based on the general idea that tall objects cast longer shadows than...

  • Tell the time with your own water clock

    In the old days telling time was not as easy as it is today. They used hourglasses, candle clocks and a device called a water clock. Do the following science experiment to learn how water can be used to...

  • Make a rainbow with water and a mirror

    A 'spectrum' consists of the seven colours of the rainbow: red, orange, yellow, green, blue and violet – as well as two other invisible colours called: ultra-violet and infra-red. Isaac Newton used a 'prism' to split up white light...
