Far away in the southern part of Earth , there was a flourishing country Ethiopia which was ruled bu King Cepheus with his wife Queen Cassiopeia. King Cepheus and queen Cassiopeia had Queenan only child- their daughter named andromeda.

Outraged and griff by Queen Cassiopeia Nereids bursted into tears. The Queen complained god poseidon. Poseidon became angry and sent a great disaster to Ethiopia. Every day when Helios flew by his gold coach in the sky, Monster whale came out in the heavy sea.

She began to cry and she couldn’t say anything. King Cepheus and Queen Cassiopeia cried for long time seeting how the flame coming out of the month of whale bunt out the country and transformed it into a desert, they decided to executive the will of gods.
Early in the morning “pinkfinger” Eous openned the door to let Helioscomed in with his gold coach Cepheus and cassiopeia look their daughter Andromeda to the rocky sea beach Andomeda was chained by her parents to a sea cliff to be caten by the monstre. Only ray on the sun caressea the fase of Andromeda. At that moment the sea fuffled. The big wove with noice smashed in the seaside rocke.
From the depth of the sea the monster whale came out. He openned a wide month and spitted a flame whale looked at Andromeda chained to rocks, openned his month wider and shower sharp teeth with his eyes blooded he rushed with fury to her.Andromeda cryied.
One more moment and the monster was going to tear her. But from heights, carried bu his wing sandalds, Perseus saw the monster coming towards the rock and listened the cry of Andromeda

He thrusted his hand in to his bag and look the head of Meduza. He turned his head not to look at in and derected its face towards the monster. At that very moment the whale transformed into a big rocky island in the rough sea.
Perseus put the head in the bag again, set Andromeda free and asked her who she was and why she was on the rock.
In tears caused bu the ehperienced horror, Andromeda, told Perseus about her evil fate. He took Andromeda to the palace of her father. Tears of happines gushed from the eyes of King Cepheus and Queen Cassiopeia as soon as they saw their beautiful Andromeda alive.

King Cepheus gave Perseus a beautiful palace and a hald of the band of Ethiopia.
Perseus didn't stay in the kingdom of Cepheus. With his wide Andromeds he went to the island of Serig to se his mother Danaia. There he found her in terrible misfortune. She hid in the temple of Zevs to run from Polidekt couldn't come out of it.

Becouse you dont't believe my words, he with your eyes. He looked Polidekt at Medusa's head and at once transformed into a stone. His friends to transformed in stone. Perseus gave the island of Sezif to Diktis, Peredikt is brother. Once Diktis had taken Peredikt and his mother from the sea with his fishing met. After that Perseus, Andromeda and his mother went to argoss where his grandfather Akrizis lived. His draudfather remembered the preduction of the oracle that he would die from the hand of his grandson and there fore evaded from Argoss far away to the north Perseus stayed and ruled his native argoss.

In 1572 a supernova exploded in the constellation and the exposion was being watched by Tiho Brahe. Accoroding to his deseription its light was compared to the light of the planet Vennus (the brightest space body after the Sun and the Moon). This star could be seen even when thick dard elounds covered the sky and no other stars could be mentioned. Now at its place radiosignals are caught. The star "y" of Cassiopeia is very interesting becouse of its unregular brighnests. In 1937 this was the brightest star in the constellatin. then its light began to decrease from 1m,6 to 3m. it can be seen with the naked eye.
Even more interesting is the star "p", visible with the unaided eye, too. It is usually of 4m but suddenly its light can decrease to 6m,2 aud it becones invisible.
The star "y is one of the most beautiful and brightest double stars. The main star of 3m,5 is yellow. Its satelite 7m,4 isred.
Near the star "B" of Cassiopeia is the radiant of the meteoflood Cassiopeiids. It can be observed fron 19 th July to 15th August. The maximum is between 25th and 28th July. Metheorids of this flood have a considerable geocentric speed - about 60 km/s.

5.Lesson

Aim:
1) To teach the students how to find out and distingnich the constellation in the real sky and in the planetarium.
2) To obtain in formation about the most interesting and the brightest object, which are included in its boundariets.

Auhiary Myths and legends about the constellations, asss. prof. means: Angel Bonov, published by Nauka i izkustvo, Sefia, 1978.

Steps:
1 To find books and magazines with information about the constellation.
2 To find sites in the Internet with information about the constellation.
3 To study and analyze the collected information.
4 To compase the data about the Cassiopeia constellation with the data about the Fishes constellation, which is the topic of the project of another group of the Peyo Yavorov schoos team.
5 To examine the constellation in the real sky and in the planetarium in order to find the brightest and the most interesting object in it
A) from Cassiopeia - a star with changeable brightuest - observing wich the naked eye
B) from Cassiopeia - a star wich changeable brightuest observing with the naked eye
C) from Cassiopeia - a double star - observing with a telescope
D) meteor stream ( flow, flood ) Cassiopeia the radiant is close to Cassiopeia - it is observed between 19th July and 15th August with its max betveen 25th-28th July.
