Warm-up

When you hear the word
astronomy
, what do you think of?

Write what
words
or
phrases
come to your mind in your science journal.

And
GO
, you have 3 minutes.


Sun-Earth-Moon System
Reading Time!
Go to Sun-Moon-Earth Assignment on Edmodo. Open the Earth's Motion reading pdf.

Describe the shape of Earth’s orbit.

What produces Earth’s revolution around the Sun?

What causes the Sun’s apparent motion across the sky?
Your Turn
The Force is With Us
Work in your small group and only use yourself as props to demonstrate how the force of gravity depends on the distance between two objects and the masses of the objects.

Science is out of this world!
Astronomy
Sunrise, Sunset
Work with a partner and use only yourselves as props to demonstrate why the Sun appears to rise and set. As you move, each student should describe what is happening to him or her.

Frayer Model
Complete a frayer model for the following vocabulary words:
Rotation
Revolution

Your frayer model must include a
definition, picture, example, and a non example
.
Exit Ticket
1. How does the Earth move?

2. The path Earth follows around the Sun is Earth’s _______.
Warm-up

Answer the following question in your science journal.

1. What causes day and night?

2. What causes the seasons?
What is your favorite season?
Launch Lab
Does Earth’s shape affect temperature on Earth’s surface?

Temperatures near the Earth’s poles are colder than temperatures near the equator. What causes these temperature differences?
Write an original 6-8 line poem that explains what causes seasons.
(Poems should be creative, but scientifically accurate, and mention both Earth’s tilt on its axis and Earth’s revolution.)
Reason for the Seasons

Why is Earth warmer at the equator and colder at the poles?

Describe how light strikes areas of the Earth near the equator.
When is Earth closest to the Sun? When is it farthest from the Sun?
How does the tilt of Earth’s rotation axis affect Earth’s weather?
Write a couple paragraphs that explain how seasons along the equator differ from seasons in a mild temperate zone.
Same Old, Same Old?
Make a list of five major cities on Earth. Locate the cities on the globe, and using Figure 5 as a reference, describe how sunlight strikes that city.
Hot or Cold?
Notebook Check
Does he or she have the Frayer Models for rotation and revolution completed?
(Definition, picture, example, and non example)
4pts

Do they have the title from Monday written down? ( As the World Turns)

What causes day and night? (The rotation of the Earth.)



Warm -up
Copy the following in your Science Journal.

What do you think?

The Moon was once a planet that orbited the Sun between Earth and Mars.

Earth’s shadow causes the changing appearance of the Moon.

After you copy the two statements, write if you agree or disagree with them.

What does the verb
waxing
mean?
What does the verb
waning
mean?
Use a dictionary to answer the following questions. (yes, you can use your iPad or your cellphone.
Warm-up
Mod 2
The craters on the moon were caused by
a. tides
b. meteoroids
c. volcanoes
d. maria
Think of two other uses of the word
phase,
either as a noun or a verb. One should be science related, the other should be an everyday use of the term.
Science Use Vs. Common Use
The portion of the Moon or a planet reflecting light as seen from Earth is called a
phase
.
Phases of the Moon
Waxing Phases
During the waxing phases, more of the Moon's near side is lit each night.
Waning Phases
During the waning phases, less of the Moon's near side is lit each night.
What is the shape of a full moon? New moon?

What produces the phases of the moon?

Describe how the Moon’s shape changes as the Moon waxes.


During which moon phase is the entire near side of the Moon visible from Earth?

Describe how the Moon’s shape changes as the moon wanes.

Why can’t an observer on Earth see the new moon phase?
Warm-up
1. The lit part of the Moon as viewed from Earth is a(n) __________.
Exit Ticket
You fist read the statements below on Monday. Did you change your mind about whether you agree of disagree with the statements? Rewrite any false statements to make them true.

The Moon was once a planet that orbited the Sun between Earth and Mars.

Earth's shadow causes the changing appearance of the Moon.
Warm-up
Name the moon phases in order, starting with the first phase the new moon.


What do you think?

A solar eclipse happens when earth moves between the Moon and the Sun.

The gravitational pull of the Moon and the Sun on Earth’s oceans causes tides.

Write if you agree or disagree with the statements.

Copy the following into your science journal.

Solar Eclipse
Define the following in your own words

Umbra
Penumbra
Warm-up
Distinguish the differences between the umbra and the penumbra?
How does a solar eclipse occur?

How do you think a lunar eclipse occurs?
Read the section in the book - When do lunar eclipses occur? on page 25
Draw a picture using one of the apps on your iPad. Share it with your classmates...post it to Edmodo
What is a lunar eclipse?

When can a lunar eclipse occur?
Where on Earth would you not be able to see the lunar eclipse?
Tides
How do tides work?

How does the total lunar eclipse differ from a partial lunar eclipse?

How would a total lunar eclipse look different from a partial lunar eclipse?
Total Eclipse v. Partial Eclipse
