Airplane pilots often make use of a device called an 'inclinometer' to give them an idea of the angle that their aircraft makes with the horizon. Make your own 'inclinometer' in the following science experiment.

A total solar eclipse, also called totality, occurs when a shadow, called an 'Umbra', falls on a region of the earth. People near it, in the 'Penumbra', see only a partial solar eclipse in which not all of the...

All magnetic fields have a similar shape no matter what the size of the magnet. The earth is in fact also a massive magnet with its gigantic magnetic field wrapping from the north to the south pole. This is...

We know that the earth moves around its own axis once every 24 hours, providing us with day and night. Other than the position of the sun in relation to the earth, there is not much evidence that the...

Various forces exist in nature that we are unable to see or feel. One such force is the force of the earth spinning at a tremendous speed around its own axis. How fast does the earth rotate? Find out...

The Chinese, Greeks and the Romans developed a device for telling the time known as a 'sundial'. Make your own 'sundial' to tell the time in this science experiment

Stars are so far away from the earth, that when you look up at the stars in the sky, you don't see the stars, but rather only the refraction patterns of their light millions of kilometers away. In this...

A good way to understand the phases of the moon is to examine the sun's effect on the moon during its various phases, with the following science experiment.

The constellations called the 'Big Dipper' and the 'Little Dipper', located in the northern sky, near the pole are often used to find the north star. You must be located in the northern hemisphere to see them both clearly...

All nine of the planets in our galaxy orbit around the sun, and the moons orbit around the planets. Orbiting bodies such as planets and moons have a balancing point called the 'barycentre', which is the gravitational centre of...
