Sky Science Review for Test
Science 6
S.O. 1 – Recognize that the Sun and stars emit the light by which they
are seen, and that most other bodies in space, including Earth’s moon,
other planets and their moons, comets and asteroids, are seen by
reflected light.
Bodies in space that emit (give off) light-
Bodies in space that reflect light-
* Meteors reflect light until they enter the Earth’s atmosphere and
burn*
*Comets are not burning*
S.O. 2 – Describe the location and movement of individual stars and
groups of stars (constellations) as they move through the night sky.
The star remains in the same location is called (3 names)______________________, ___________________, __________________
4 constellations found in the Northern Sky

S.O. 3 – Recognize that the apparent movement of objects in the night
sky is regular and predictable, and explain how the apparent movement
is related to Earth’s movement.
Why do the stars appear to move across the sky at night?
_____________________________________________________________
Draw the position of the big dipper (Ursa Major) in each season:
S.O. 4 – Understand that the Sun should never be viewed directly, nor
by the use of simple telescopes or filters, and that safe viewing requires
appropriate methods and safety precautions.
 Looking directly at the Sun causes damage to our eyes that cannot
be repaired.
 It is also dangerous to look at the Sun with cloud coverage, or
during an eclipse.
 The safest way to view the Sun is to use #14 welder’s glasses.
 It is also possible to create a pinhole camera, which is designed to
show the reflection of the Sun.
S.O. 5 - Construct and use a device for plotting the apparent movement
of the Sun over the course of a day; e.g., construct and use a sundial or
shadow stick.
How does a sundial work? How does a shadow stick work?
Why aren’t shadow sticks and sundials reliable?
What is important when considering where to position these devices?
How will the length and position of a shadow change through a day?
(morning, noon, evening)
How will the length and position of a shadow change in relation to the
seasons? (winter, spring, summer, fall)
Draw a diagram of how you would use a shadow stick to determine time.
Make sure you label everything you use/need.
S.O. 6 - Describe seasonal changes in the length of the day and night and
in the angle of the Sun above the horizon.
Draw the position of the Earth in relation to the Sun in each season.
Make sure you include the tilt of the Earth’s axis in each of the diagrams.
Label the following:
Summer Solstice
Autumn Equinox
Winter Solstice
Spring Equinox
Label the appropriate dates for each Earth position.
12 hours of day and night occur on ___________________ and
__________________
The Northern hemisphere has more daylight hours in which season?
______________________
The Southern hemisphere has more daylight hours in which season?
___________________
Describe the angle of the Sun for each season. How does this affect
temperature?
