Lesson 1

I can recognize that the sun and stars emit the light by which they are seen and that most other bodies in space are seen by reflected light.

Emitted versus Reflected Light Emit – to send or give out Objects that emit light are sources of energy and give off heat and light Reflect – to cast back Objects that reflect light are seen by the objects that emit light Read Notes about stars and comets in our books. Make a class collage

Comets, Asteroids & Meteors Comets: They are made out of dust and ice, kind of like a dirty snow ball. Asteroid: An asteroid is a large rock in outer space. Meteoroid: a sand to boulder-sized debris in the solar system. Called a meteor when it enters Earth’s or another body’s atmosphere: AKA shooting or falling star Called a meteorite if it reaches ground and survives

Lesson 2

Write these down! I can describe the location and movement of individual stars and groups of stars (constellations) as they move through the night sky. I can recognize that the apparent movement of objects in the sky is regular and predictable. I can explain how the movement of objects in the night sky are related to Earth’s rotation.

Astrology – the study of stars in order to predict future events Astronomy – scientific study of celestial objects outside Earth’s atmosphere Astrology – the study of stars in order to predict future events Greeks tried to make sense of the stars by observation Found out that Earth revolves around the Sun and the Moon revolves around Earth One way they observed the stars was to cluster them into constellations Can you name some???

Constellations Ursa Major Big Dipper Ursa Minor Little Dipper Cassiopeia Cepheus Draco polar constellations - very close to the North Pole. If stars are close enough to the pole they never set below the horizon and we can see them all year long Circumpolar means to circle around the pole. They move in a counterclockwise direction.

Big Dipper/Ursa Major

Can you find the Big Dipper?

Info. About the Big Dipper Not really a constellation It's what's called an 'asterism‘ - a highly recognizable part of a constellation The full constellation actually is Ursa Major Arcturus – one of the brightest stars in the Big Dipper because it is the red giant Why is it so important? The Two Pointers point to the north star – Polaris (in the Little Dipper)

Can you find the Big Dipper in Ursa Major using your iPad Can you find the Big Dipper in Ursa Major using your iPad? *** Record your observations

Little Dipper/Ursa Minor *** Record your observations

Cassiopeia and Cygnus

Cassiopeia/Queens Throne and Cygnus/The Swan Cassiopeia/Queens Throne and Cygnus/The Swan *** Record your observations on master 2c

Orion – only seen early winter to late spring *** Record your observations

Myth Sharing Using the links found in your Gmail, search up the constellation assigned to you and research the myth associated with it On your index card, write some key points about your constellation’s story Be prepared to share with the class!

CONSTELLATION NOTES There are 88 official constellations Some constellations are visible in only the northern or southern hemisphere Constellations are also visible based on which season it is of the year because of the Earth’s rotation around the Sun

Star Finders Cut around the dotted line Glue the Star Finder to another piece of hard paper or a file folder – trim off the excess paper/file folder Staple – where it says staple Cut out circles – with constellations and glue them together

Lesson 3

I can understand that stars all have a life cycle I can also understand that the different stars in the universe emit light and are classified based on size, colour, temperature and brightness.

What is a Star? A star is a big ball of burning gas Fusion happens in the core of the star This creates heat and light that is emitted from the surface of the star Stars have life cycles from birth to death

All stars are formed in a STELLAR Nebula Depending on the initial size of the star, it follows one of two life cycle paths These life cycles take billions of years!

TYPES OF STARS Stellar Nebula Main Sequence Star -Massive Star Red Giant -Red Supergiant Planetary Nebular -Supernova White Dwarf -Neutron Star/Pulsar Star Black Dwarf -Blackhole -Brown Dwarf -Binary Star
