Identifying Patterns of ChangeThe student is expected to identify
patterns of change such as in weather, metamorphosis, and objects in the sky.

VocabularyChange- To make or become different.Cycle- A course or series of events that recur regularly
and usually lead back to the starting point.Metamorphosis- A change of physical or structure
(transformation).Revolve- To travel in a closed path around an object
such as Earth does as it moves around the Sun.Rotate- The spinning of an object on its axis.Phases of the moon- The illuminated changes of the
moon as viewed from Earth due to its motion around the Earth.

VocabularyAxis- An imaginary line that passes through Earth’s center
and its North and South poles.Season- A period of the year characterized by or
associated with a particular type of weather phenomenon due to the tilt of the Earth’s axis.
Weather- The state of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness.
Fronts- Fronts occur where two large air masses collide at the Earth’s surface.
Cold front- This occurs when a cold air mass pushes under a warm air mass.
Warm front- This occurs when a warm air mass slides on top of a cold air mass.

Life Cycle of a Frog

Froglet Adult Frog
10 days
At 10 days the tadpole
leaves the egg.
At 8 weeks the back legs have formed.
At 12-14 weeks the tail
begins to disappear.
It takes about 3 years for the frog to reach adult hood.

Comparing Tadpoles to FrogsComparing Tadpoles to Frogs
Tadpoles Frogs
Tadpoles have gills.They lose their gills and
breathe with lungs.
Tadpoles have tails.They lose their tails
when they become frogs.
Tadpoles cannot reproduce.
Frogs can reproduce.
Tadpoles cannot live on land.
Frogs can live on land.

A cold front occurs when a cold air mass pushes under a warm air mass. Weather associated with cold fronts
involves low pressure systems that are usually severe and may include thunderstorms, hail, and a drop in
temperature.
16
A warm front occurs when a warm air mass slides on top of a cold air mass. Weather associated with warm fronts is usually less severe and may include steady, light precipitation with warmer, dryer air.

Phases of the Moon
NEW MOON
The illuminated side of the moon is not facing the Earth, therefore the moon is not visible from Earth.
20
Phases of the Moon
WAXING CRESCENT
From Earth, the moon appears to be partly illuminated.
In this phase less than half of the moon appears illuminated.
The illuminated portion is increasing in size from our point of view on the Earth.
21
Phases of the MoonFIRST QUARTER
From Earth, half of the moon appears to be illuminated.
The moon has completed one-fourth of its revolution around the Earth.
The illuminated portion within our view is increasing in size.
22
Phases of the Moon
WAXING GIBBOUSFrom Earth, more than
half of the moons surface appears to be illuminated.
The illuminated portion within our view is increasing in size.
23
Phases of the Moon
FULL MOON
The moon’s illuminated side is facing the Earth.
From Earth, the moon appears to be completely illuminated.
24
Phases of the Moon
WANING GIBBOUSFrom Earth, the moon
appears to be more than half illuminated.
The illuminated portion within our view is decreasing in size.

Phases of the Moon
LAST QUARTERFrom Earth, half of the
moon appears to be illuminated.
The illuminated portion within our view is decreasing in size.

What are eclipses?
An eclipseeclipse occurs when an astronomical body such as a
planet or moon is between the Sun and another body (planet or moon).
From Earth, we experience two types of eclipses: lunar eclipses
and solar eclipses.
