StarsThere are billions of stars in the milky way
galaxy.A Star is a huge ball of burning gas with an
intense heat and light.The sun is the nearest star from the earth and
is not solid.Consist out of burning gasses with very harmful
ultra violet beams.The Sun is in the middle of our solar system.The Sun is the main source of light & heat and
produce its own light. 7

The sun works as a magnet keeping the planets in place.
Every planet orbits around the earth and revolves around its own axes.
Earth axes are not round but ovalThe shape is called ellipse.

DAY & NIGHTAt any given time during the Earth’s rotation
around its own axis, half of the Earth is facing the sun and has daylight while the other half is in darkness.
As the Earth turns, the half in daylight moves towards the darkness and nighttime while the half in darkness moves towards the light and daytime.
Remember the Earth turns from West to East. EXPERIMENT : GLOBE & TORCH PRESENTATION: DAY/NIGHT

What’s the time? Imaginary lines run from the North Pole to the
South Pole. These are called lines of longitude. They help us to pinpoint locations on the Earth’s surface as well as to determine the time at any given place on Earth.
The Greenwich Meridian is found at 0˚ longitude. There are lines 180˚ east and west of the Greenwich Meridian.

The time is determined by adding one hour to the time at the Greenwich if you move east and subtracting one hour to the time at the Greenwich if you move west. Eg. 5 o’clock in the afternoon in Cape Town and 12 0’clock midnight in Perth.
