Space Facts for 6th Grade

http://www.youtube.com/watch?v=SB_Qfngi0mo

The movie referenced below is 44 minutes long and detail 13 of the greatestAstronomy discoveries of all time.

Following are a series of slides related to our study of space.

You are responsible for the definitions given you in class.

You are also responsible for the material listed on the concept sheet.

The links are for you to enjoy but will be gone over in class so aren’t

required.Slide2

big bang theory

A cosmological theory holding that the universe originated approximately 20 billion years ago from the violent explosion of a very small agglomeration of matter of extremely high density and temperature.

Earth

The Earth is the third planet in order from the sun,having an equatorial diameter of 7926 miles (12,755 km) and a polar diameter of 7900 miles (12,714 km), a

mean distance from the sun of 92.9 million miles (149.6 million km), and a period of revolution of 365.26

days. Earth has one satellite, the moon.

hemisphere

A hemisphere is half of

the terrestrial globe

or

celestial

sphere,

especially

one

of

the halves into which the earth is divided.

Southern Hemisphere

Northern Hemisphere

Eastern Hemisphere

Western Hemisphere

axis

An axis is a line about

which a rotating

body,

such as

the

E

arth

,

turns.Slide6

An equinox is one of two date(s) at which the axis of the sun is directly parallel the sun. March 21 and Sept 21.

equinox

Equinoxes are days in which day and night are of equal duration. The two yearly equinoxes occur when the

Sun

crosses the celestial equator. Slide7

solstice

The solstices are days when the Sun reaches its farthest northern and southern declinations. The winter solstice occurs on December 21 or 22 and marks the beginning of winter (This is the shortest day of the year in the northern hemisphere.). The

summer solstice occurs on June 21 and marks the beginning of summer (This is the longest day of the year. In the northern hemisphere).

A

solstice

is one of two

date(s) at which the axis of the sun is pointed directly toward or away from the sun. June 21 and December 21Slide8

seasons

http://www.youtube.com/watch?v=DuiQvPLWziQ

Seasons are changes in climate (temperature, water, etc.) caused by the position of the Earth’s axis due to receiving different amounts of the sun’s energy as the Earth revolves around the sunSlide9

tide

Tides are the periodic rise

and fall of the

waters

of

the

ocean and its inlets, produced by

the

attraction

of

the moon and sun, and

occurring about every 12 hours.

Slide10

sun

The sun is a glowing ball of plasma – a yellow star.

The sun contains 99.86% of the

m

ass of the solar system. It is over

99% hydrogen with 1% helium. The

Sun is a yellow dwarf star.Slide11

solar eclipse

A solar eclipse occurs when the moon comes between the sun and a

point on the earth.

star

A star is a massive, luminous sphere of plasma held together by gravity. (plasma – a hot glowing ball of gases.

The Hertzsprung–Russell diagram is a scatter graph of stars comparing their brightness (absolute magnitude) and temperature (which causes their color). H-R diagrams are

not

pictures or maps of the locations of the stars. Instead, they plot each star on a graph measuring the star's absolute magnitude or brightness against its temperature and color.Slide13

the m

oonThe natural satellite of Earth, visible by reflection of sunlight and having a slightly elliptical orbit.

Dark areas are called

maria

(seas) and are flat areas like plains. Light areas are

terrae

(land) where there a mountains and craters.

It takes 28 days for the

moon to orbit the Earth.

Apollo 11

was the

spaceflight

which landed the first humans,

Neil Armstrong

and

Edwin "Buzz"

Aldrin

, Jr, on Earth's Moon on July 20, 1969, at 20:17:39

phases of the moon

The phases of the moon are changes in the moon’s appearance due to its position relative to the sun and Earth.Slide15

moon

A moon is a natural object that rotates around a planet or planetoid.

Earth’s moon revolves around the

Earth every 28 days and is about

250,000 miles from Earth. Earth

has one moon that stabilizes

Earth’s orbit.

Saturn has more than 30 moons.

Why do we only see one side of the moon? Watch this video.Slide16

lunar eclipse

http://www.youtube.com/watch?v=DU-mW-qy4PU&feature=related

A lunar eclipse occurs

when the

moon passes

behind the

Earth

so that the Earth blocks the

sun's

rays from striking the Moon.

During a total lunar eclipse, the

m

oon appears to be red and is

s

till visible.Slide17

rotation

A rotation is the act or process of turning around a center or an axis: the axial rotation of the Earth

is responsible for night and day and the day length.

elliptical rbit

An

elliptical orbit

is the revolving around and object by another object in a path called an ellipse.

plane of the

eclipticThe ecliptic is the name given to the imaginary line that is drawn on the celestial sphere ( star maps ) that shows roughly the plane of the Solar System

revolution

A revolution is a single complete cycle around another body in space.

solar s

ystemhttp://www.apples4theteacher.com/starwarp2.html

The solar system is the collection of planets and their moons in orbit around a sun, together with smaller bodies; asteroids, meteoroids, and comets.

http://

www.kidsastronomy.com/solar_system.htm

Earth’s solar system

has eight planets,

two planetoids,

numerous moons,

and other objects.Slide22

constellation

A constellation is a group of stars given a name by group of people.Ursa Major – the great bear

the scorpion

the hunter

the swanSlide23

constellation: Ursa Major (the big bear)

North Star

Polaris

The name "The Great Bear" seems to have been assigned to the constellation in antiquity, due to its northern latitudes. Only a prodigious bear could live in such a northerly clime.

http://www.allthesky.com/constellations/ursamajor/Slide24

constellation: Cassiopeia

Cassiopeia is a constellation in the northern sky, named after the vain queen Cassiopeia in

Greek mythology, who boasted about her unrivalled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd century Greek astronomer

Ptolemy

, and it remains one of the 88 modern constellations today. It is easily recognizable due to its distinctive 'W' shape, formed by five bright stars. It is bordered by

Andromeda

to the south,

Perseus

to the southeast, and

Cepheus

to the north. She is opposite the

Big Dipper

, and from northern latitudes can be seen at her clearest in early November.Slide25

constellation: Scorpius (the scorpion)

Scorpius

is one of the oldest constellations known - possibly even one of the original six signs of the zodiac.

Gaia

sent

the scorpion to kill Orion. The animal would chase Orion across the heavens, but it could never catch him, for the scorpion was so placed that it would rise in the east only after Orion had safely disappeared over the western horizon. Slide26

constellation: cygnus (the swan)

Several

extrasolar

planets

including

HAT-P-7b

,

HAT-P-11b

,

HD 185269 b

,

HD 187123 b

and

c

, Gliese 777 b and c, and 16 Cygni Bb

, have been discovered in Cygnus, but the most notable is Kepler 22b, which is believed to be the first "Earth-twin" planet ever discovered, with an estimated average surface temperature of 73 degrees Fahrenheit.Slide27

constellation: Orion

Orion is one of the most well-known constellations, visible in the southern sky during northern hemisphere winters. He is generally shown as a hunter attacking a bull with an upraised club, and is easily recognizable by his bright belt of three stars. In addition, his shoulder is marked by the red supergiant Betelgeuse (literally "armpit of the central one" in Arabic), and his left leg is marked by the blue-white supergiant

Rigel. According to the versions of the myth which have him killed by Scorpius, the two were placed on the opposite sides of the sky from each other so that they are never visible at the same time.

The middle star in

Orion’s sword is

actually a

nebula, a

s

tar that went nova

In 1054.Slide28

galaxy

A galaxy is an assembly of stars, gas, and dust, usually consisting of millions of stars.

There are many types of galaxies.http://www.youtube.com/watch?v=LBlIEs73LGwSlide31

black hole

A black hole is a region of space time from which nothing, not even light, can escape.Slide33
