3. Lesson 1

5. 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.

6. 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

9. 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

13. Lesson 2

14. 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.

15. 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???

17. 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.

18. Big Dipper/Ursa Major

19. Can you find the Big Dipper?

20. 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)

21. 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

22. Little Dipper/Ursa Minor *** Record your observations

24. Cassiopeia and Cygnus

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

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

28. 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!

30. 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

31. 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

32. Lesson 3

33. 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.

34. 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

36. 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!

37. 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
