The Ancient Egyptians were very much keen to understand the night sky. They began their research on stars in around 4000BC. There were numerous reasons why the Ancient Egyptians studied astronomy. The foremost reason was that stars can help to know the time. In the ancient times it was very essential for the Egyptians to have an accurate calendar that could provide them an idea about when to plant and harvest crops for food. After a regular observation and extensive analysis of stars the Egyptians discovered that a day has 24 hours. With this fact they discovered an year-long calendar that included 12 months with 30 days.
The Egyptians also observed that the position of stars did not fluctuate but there appeared other objects that did not stop moving at a different speed and sometimes disappearing for a while. The ancient Egyptians called these objects 'the stars that know no rest' which we today know as the planet Venus, Mercury, Mars, Saturn & Jupiter.
The pyramid also has an interesting story discovered by the old Egyptians. There are today two shafts built on to the sides which were built at the location facing the passing of two stars. One was Thuban, that was near to the Pole Star and Alnilon, a star situated in Orion's belt. The ancient Egyptians discovered the Orion with 'Osiris', who was known to be the god of rebirth.
There are much more reasons and stories as why the Ancient Egyptians studied astronomy. With the advancement in technology you can now teach your students astronomy in a more interesting and convenient way. Since, most students have never seen a night sky that is not destroyed by pollution. So, without having to spend on field trips, you can get portable planetarium that usually consist of an inflatable room with a potential to accommodate about thirty students. Inside is a novel projector that can take your students to the night sky. You can make them watch real stars, planets, the moon and the minutest of details hidden in the cloudless night sky. By simply changing the projection cylinder, the can even draw outlines of a globe of the Earth, constellations or a diagram of the human cell and much more. Without much hassle and efforts, now you can make your astronomy students learn about the changing motions of the sun, moon, stars and planets just in a few minutes.
