Planet EarthNATURAL SCIENCES GRADE 52How the Earth MovesThe Earth moves in two different ways:

1. The Earth moves around the Sun

NATURAL SCIENCES GRADE 5(Click on Play to play the animation. There is no sound)3How the Earth moves around the Sun

NATURAL SCIENCES GRADE 5The Earth moves in an oval shaped ORBIT (pathway) around the Sun

The Earth takes 365 days (1 year) to complete one orbit

4Orbits of Other PlanetsOther planets take a longer or shorter time than a year to orbit around the Sun. Have a look at this story

Click on link for animated story with audio.5How the Earth MovesThe Earth also spins on its own AXIS (an imaginary line)The axis does not moveThe line is tilted at an angleWe can compare it to this picture

Click on Play no sound6When the Earth has made a full turn, we call it a ROTATIONIt takes 24 hours for the Earth to make a full rotationThis is how we have night and day

NATURAL SCIENCES GRADE 57The Earth spins, and so we have Night and Day

Egypt is in the dark. It is night time thereThe suns rays are beaming down on South Africa - it is day time in South AfricaAs the Earth keeps turning, different countries will experience day and night South AfricaEgypt

NATURAL SCIENCES GRADE 58 Lets Practice! Can you see Africa in this picture?If you lived on the red dot, would it be day time or night time?If you lived on the purple dot, would it be day time or night time?
