· The moon has no atmosphere and is unable to support life. There is no weather on the moon.
· The moon’s surface is rocky. It has craters, mountains, and plains.
· There is no water on the moon.
· The moon rotates in about a month.
· Earth supports a great variety of plant and animal life. Because Earth has an atmosphere and it has water, we experience all kinds of weather.
· Earth has a few craters, mountains, and plains.
· The Earth rotates in about a day.
· A solar eclipse happens when the Earth passes through a new moon’s shadow.
· A lunar eclipse happens when the full moon passes through the Earth’s shadow.

Comparing Earth and Moon
When the Earth and moon first formed they were both very hot. Because the Moon is smaller and has less mass than Earth, it cooled rapidly. Deep moonquakes tell us that the moon may have a partially molten core. The Earth is almost four times larger than the moon. It did not cool completely and has a large molten core.
The Earth’s internal heat causes the crust to be broken up into moving plates. The moving plates cause earthquakes and build mountain ranges. There are only small mountains on the Moon. They are the remains of extinct volcanoes or formed when meteorites slammed into the Moon’s surface. The lowlands on the Moon (called marias) were formed from past lava flows. Maria means "seas" because the first astronomers thought the smooth, dark plains were oceans.
Only meteorites cause erosion on the Moon’s surface. They create craters and make rays that look like white streamers radiating out from the edges of craters. Craters formed on Earth by meteorites have been eroded way over time. Without an atmosphere or weather on the Moon, wind and water can not disturb its dusty and rocky surface. On the Moon no soil is produced, the sky is always dark, and the temperature range is much higher during te day and much lower at night than the Earth’s.
When the moon formed, it did not have enough gravity to hold onto an atmosphere. That means there is no air to breathe on the moon. There is also no weather. When Earth formed, an atmosphere developed around it. Earth’s atmosphere is made up of gases. We get the oxygen we need to breath from the atmosphere. Earth has weather because it has an atmosphere that includes air and water.
The distance around the moon (circumference) is almost 4 times smaller than Earth’s circumference.
Hmm! Scientists think that a large object the size of Mars slammed into the Earth sending its crust and mantle into space which eventually formed the Moon.

· The sun is the only star in our solar system. It is the largest object in our solar system.
· The most important source of energy for Earth is the sun.
· The sun provides light energy and thermal (heat) energy.
· The sun’s gravity keeps the Earth and the other planets in our solar system in orbit around it.
· The sun is made of burning gases, mainly hydrogen and helium.
· The sun is not the same temperature all over. Sunspots are dark areas that appear on the sun. These places are not as hot as the rest of the sun.

The Sun, Earth and Moon.
What we need to know in 5th grade:
· The Earth is part of the solar system.
· The Earth orbits the sun once a year.
· The moon revolves around the Earth once a month.
· The Earth rotates once a day.
· The Earth orbits the sun and the moon orbits the Earth.
· Models help us to understand things that are too small, too big, or too far away to work with.

· Models help us to understand things that are too small, too big, or too far away to work with.
· We always see the same side of the moon.
· We see the moon because it reflects light from the sun.
· How the moon looks to us is different every day because the Earth and moon are constantly moving.
· The different ways that the moon seems to look in the sky are called moon phases.
· The main moon phases are new moon, first quarter moon, full moon, and third (last quarter moon).

- planet: a large body that goes around (orbits) the sun
- comet: a chunk of ice and dust that orbits the sun
- asteroid: rocky and metallic object that orbit the sun that are too small to be considered planets

What about Pluto?
Pluto is now called a "dwarf planet."
Pluto is now called a "dwarf planet."
- So our solar system now has 8 planets and several dwarf planets.
- Scientists used the data they have gathered over many years to define what makes a planet a planet. Planets are now defined as a celestial body that:
- is in orbit around the sun.
- has sufficient mass to assume a nearly round shape
- clears the neighborhood around its orbit.
- Pluto meets the first two criteria, but not the third because Pluto crosses inside Neptune's orbit. Based on this information, the characteristics of Pluto do not match the definition for a planet.
- Ceres, Eris, Haumea, and Makemake are also classified as dwarf planets.
- Most asteroids, comets, and other small objects will be called "small solar-system bodies."
scale: a way to show the relationship between distance on a map (or in a model) and real distance
model: an object that looks like the real one, but in a smaller or bigger
size
inner planet: the planets in our solar system that are between the sun
and the asteroid belt; Mercury, Venus, Earth, and Mars
outer planet: the planets in our solar system that are located beyond
the asteroid belt; Jupiter, Saturn Uranus, and Neptune
