Georgia Performance Standards

• S4E2. Students will model the position and motion
  of the earth in the solar system and will explain
  the role of relative position and motion in
  determining sequence of the phases of the moon.
• a. Explain the day/night cycle of the earth using
  a model.
• b. Explain the sequence of the phases of the
  moon.
• c. Demonstrate the revolution of the earth around
  the sun and the earths tilt to explain the
  seasonal changes.
• d. Demonstrate the relative size and order from
  the sun of the planets in the solar system.

Vocabulary

• ? revolution
• ? orbit
• ? satellite
• ? axis
• ? rotation
• ? phases
• ? gravity

• Keep an eye out for these yellow vocabulary
  words. They will appear throughout the
  presentation. Have 7 index cards ready to create
  your vocabulary flash cards. Try to guess what
  you think each word means after seeing it in the
  presentation.

5
Earth

• It takes Earth one year (365.25 days) to make a
  complete revolution around the sun.
• Earth has a certain path it takes around the sun
  called its orbit.
• A satellite is an object that moves around
  another object in space.

• While Earth revolves around the sun, it spins on
  an imaginary line called its axis.
• The axis runs from the North Pole to the South
  Pole.
• Earth takes one day (24 hours) to complete one
  rotation on its axis.

6
Day and Night

• What do you think causes day and night?

When Earth makes one rotation on its axis (24
hours), day and night occur. The sun lights up
the side of Earth that is facing it for daytime
and the other side has nighttime.
7
Seasons

• ? Earths axis is slightly tilted.
• ? Seasons are caused by Earths tilted axis and
  the revolution Earth makes around the sun each
  year.
• ? For part of each year (1/4), the Northern
  Hemisphere tilts towards the sun and the Southern
  Hemisphere tilts away. This causes summer in the
  Northern Hemisphere and winter in the Southern
  Hemisphere.

Seasons
9
The Moon

• It take a little more than 28 days for the moon
  to complete its orbit around Earth.
• The moon does not give off its own light-it
  reflects the light from the sun.
• The moon seems to have different shapes, or
  phases because of the way the suns light is
  hitting it.

Weight on Other Planets

• Gravity affects how much you weigh. Gravity is a
  pulling force. If a planet has more gravity then
  here on Earth, you will weigh more. If a planet
  has less, then you will weigh less. This table
  shows your weight throughout the Solar System if
  you weigh 100 pounds here on Earth.

14
Age on Other Planets

• A year represents one revolution around the sun.
  Planets travel at different speeds and some have
  larger orbits. This would affect your age on
  different planets. This table shows how old you
  would be on other planets if you were 10 here on
  Earth.

Measure the Solar System!Materials meter stick,
adding machine tape (15 meters long), pencil,
marker
Directions In groups of five use the table to
create a model of the solar system. Draw a
vertical line at the beginning of the tape for
the sun. Each measurement given is to be measured
from the edge of the sun. Mark you measurements
with a pencil. Use the marker to dot and label
each planet measured.
