3
Rotation of the Earth
The Earth spins and moves around the sun.
The spinning of the earth is called rotation.
It takes the earth abut 24 hours, or one day, to make one complete rotation
4
Revolution
The earth is moving around the sun. This is called a revolution. It takes a little over 365 days, or one year, for the earth to make one full revolution around the sun.
5
Multiple Choice
It takes Earth 24 hours to complete one rotation.
6
Multiple Choice
It takes the Earth 365 days to complete one revolution.
7
Earth's Tilt
As the earth spins, it also tilts. It is because of this tilt that we have seasons. This will change how high the sun will get in the sky.
The tilt is 23.5 degrees,
8
Seasons
The seasons are caused by the revolution of the Earth around the sun and the tilt of the Earth’s axis

Inner Planets
Our solar system has four inner planets. Mercury, Venus, Earth, and Mars are closest to the sun.
They are called terrestrial planets and are largely made of rock and metal.
12
Outer Planets
Jupiter, Saturn, Uranus, and Neptune
They have ring systems. Saturn, for example, has an enormous ring. It can hold a billion Earths.
The outer planets are made up of gases that swirl around in cold, windy storms.
They are called gas giants. They formed in an extremely cold area of the solar system.
13
Earth
Earth is the only planet in our solar system that is known to support life.
It is just the right distance from the sun to have water and oxygen.
Our atmosphere is made up of layers of gases. The atmosphere protects us from being harmed by the sun’s rays

Moon Phases
Remember, light from the right.
The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth
17
The Apollo Missions
The Apollo program, also known as Project Apollo, was the third United States human spaceflight program carried out by the National Aeronautics and Space Administration, which succeeded in landing the first humans on the Moon from 1969 to 1972.

Solar Eclipse
A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth.
A solar eclipse can only take place at the phase of new moon.
20
Lunar Eclipse
A lunar eclipse can occur only at full moon.
A total lunar eclipse can happen only when the sun, Earth and moon are perfectly lined up
21
Tides
High and low tides are caused by the moon.
The moon's gravitational pull generates something called the tidal force.
The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
22
The Sun
The Sun is a yellow dwarf star, a hot ball of glowing gases
Its gravity holds the solar system together
Electric currents in the Sun generate a magnetic field that is carried out through the solar system by the solar wind
The Sun produces energy through fusion.

24
Elliptical galaxies
About one-third of all galaxies
They have little gas and dust, contain older stars and are not actively forming stars anymore.
25
Spiral galaxies
Spiral galaxies are twisted collections of stars and gas that often have beautiful shapes and are made up of hot young stars.
26
Irregular Galaxies
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy.

Multiple Choice
The phases of the moon remain the same each night.
