Lesson for grade 9 science quarter 3 focuses on constellations and stars
Stars are powerful balls of flaming gases that emit electromagnetic waves
Our galaxy has approximately 400 billion stars and there are about 170 million galaxies
The sun is a medium-sized star, 150 million kilometers away from Earth
A star can be defined by brightness, color, surface temperature, size, and mass
Star's brightness depends on size, temperature, and distance from Earth
Star's color indicates its surface temperature, ranging from red to blue
Stars come in various sizes - from white dwarfs the size of Earth to giants filling our solar system
Mass determines a star's life cycle - low mass stars become white dwarfs, high mass stars end in supernova explosions leaving behind black holes
Stars originate from huge gas and dust clouds called nebulae
Constellations are groups of stars forming imaginary patterns, with names tracing back to ancient civilizations
Different cultures have diverse names for constellations, like Orion the hunter or Taurus the bull
Earth's revolution causes different constellations to be visible at different times of the year
There are 88 constellations recognized by the International Astronomy Union
Zodiac signs are based on 12 specific constellations
Some constellations appear and disappear in the night sky due to Earth's revolution
Constellations seem to move across the night sky due to Earth's rotation on its axis
Examples of constellations include Scorpius the scorpion, Virgo the maiden, and Pegasus the winged horse

Test your knowledge on constellations, stars, and their characteristics like brightness, color, size, and mass. Learn about the life cycles of stars based on their mass and the formation of stars from nebulae. Explore how Earth's revolution affects the visibility of constellations throughout the year.
