Transcript EARTH'S ROTATION AND REVOLUTION

Day 1:
Objective: Students will understand
that the appearance of the moon
changes in a predictable cycle as it
orbits Earth and as Earth rotates on
its axis.
What are our “I Can” statements?
Lesson Title:
ROTATION AND REVOLUTION
Essential Question
• What are axis, rotation, and
revolution and how do they
relate to the sun, moon and
earth connection?
Earth’s Rotation
• Rotation is the spinning
of the Earth on its axis.
• The time for one rotation
is 24 hours.
• It rotates
counterclockwise.
• The speed of rotation
24,855 miles/24 hr or
1,038 miles/hr

Earth’s Revolution
• A revolution occurs as the earth moves
around the sun.
• Time for one revolution = 365 1/4 days
= 8,766 hours
• The speed of earth’s revolution is
about 18 miles per second.
Earth’s Revolution
An example:
Another way to think of these
vocabulary terms is to go to the
world of ice skating. As you
skate around the ice rink, that is
like a revolution, or orbit. If you
spin on the toe of your skate,
you are completing a rotation.
Earth’s Orbit
• The path an object takes as it revolves around
another object.
Around and Around We Go
• Every second, that you sit in
this classroom, the Earth's
orbital motion carries you
about 18 miles through
space.

Question Starters:
After you have finished taking notes, it
is important to add questions about the
material that you can later use to quiz
yourself or a friend.
Turn to “Question Starters” in your
interactive notebook.
Awesome job today students!
