The universe is everything that exists, including all matter everywhere.
Astronomy is the study of what is beyond earth.
Constellations are groups of stars that seems to form shapes or patterns

Objects in our solar system
1. Sun
5. Mars
2. Mercury
6. Jupiter
3. Venus
7. Saturn
4. Earth
8. Uranus
Planets and moons are non-luminous and do not emit light.

Effects of planetary motion
Section 13.3 pages 404-407
Rotation: when an object (planet) spins around an axis or straight line from
top to bottom. The axis of the earth goes through the north and south pole.
It takes the earth 24 hours to make one rotation. This is what caused day
and night to occur on earth.
Revolutions are the length of time required for an object to make one turn
around another. It take the earth 365 days to travel around the sun.
The effects of the earths revolutions
1. Enables us to see different stars and planets at different times of the
year.
2. Combined with rotations on an axis they are responsible for the
seasons of the year.

Properties of planets in the Solar System
Pages 418 chart with statistics on planets
Name: ___________________________________________
Date: ___________________________
Activity: Drawing a large scale model solar system.
Equipment:
Need string and side walk chalk.
Form complete with correct information
Masking tape
Work:
1. Find the ratios of planet size (radius) and planet distance (radius) from
the sun.
2. Find the individual size of each planet and the distance from the sun,
write this information down. Make a chart to help you.

Distance from cm
sun
3. Cut two strings, one for planet size radius and one for planet distance
from the sun radius, using masking tape write down the size of the
planet’s radius, this needs to be done ten times, including the size of
the sun. Using masking tape write down the radius of each planets
revolution around the sun this needs to be done 9 times.
4. Provide a sketch of the diagram that you will create outside on the
pavement; include distances and anything else that could help you.
Additional work:
1. Include an explanation of comets and how you might represent comets
on you large scale diagram of the solar system.
