Earth Science & Astronomy

  • Map how far the sun is from the moon

    The moon is approximately 380,000 km from the earth and the sun is about 1,500,000,000 km away from the earth. It is very difficult to interpret and understand what these distances mean, but the following science experiment should shed...

  • 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...

  • Defying gravity with centrifugal force

    Gravity can be explained as the force with which the earth attracts bodies near its surface. You will know the effect of this force if you have ever fallen down on the playground! One way to work against the...

  • Study the effect your location in a tall building have on gravitational pull

    Even though some forces exist in nature that we are unable to see, we still are able to see what effect such forces, such as 'gravity' can have with some interesting science experiments. Gravity can be explained as the...

  • Study the force of gravity with this simple experiment

    A scientist called 'Galileo', put forward the theory that all objects are pulled down to earth due to gravity, at the same speed, no matter their weight. Try to prove Galileo's theory for yourself in the following science experiment.

  • Find some rare earth metals in ordinary garden soil

    Feel like doing some mining for rare metals in your own garden? The dirt in ordinary garden soil can contain very small particles of magnetic material or 'metals'. In this science experiment, find and study this particles with a...

  • Measure the extend of creeping soil on hillsides

    Hillsides are prone to moving or 'creeping' soil where the soil creeps along in a gradual downward flow. Use a protractor and a weight to determine the amount of 'lean' in objects such as trees, posts and other vertical...

  • Use the continents of today as puzzle pieces to reconstruct the past

    Scientists believe that all present continents were once joined together and collectively known as a 'supercontinent' called a Pangaea. The different continents drifted slowly apart and became the way they are today. See if you can reconstruct the map...
