TEST ON THURSDAY, OCT. 1st
7th Grade Solar System/Manned Space Exploration Test Review
Know the key terms: Defined in your notes.
Solar System
A large planetary system that consists of
a combination of many smaller planetary
systems and objects.
Revolution
Extraterrestrial Life
Rotation
The movement of an object around
another larger object. (year)
Life that arises outside of Earth.
The spinning motion of a planet about its
axis (day).
Gravity
The attractive force between
two objects magnitude depends on their
masses and the distance between them.
Atmosphere
The mixture of gases that surrounds the
Earth.
A large satellite that can support a human
Space Station
crew and remain in orbit around Earth.
Study the power points – General Space and Habitable planet (all on weebly)
Our planet resides within the Milky Way Galaxy
Our universe consists of systems within systems
Solar System includes the Sun, planets, natural satellites of planets (moons) and minor
objects, called asteroids, comets and meteoroids
TEST ON THURSDAY, OCT. 1st
Its gravitational pull keeps the planets from shooting off into space. If the Sun disappeared
the planets would move in a straight line.
Planets are large bodies that orbit a star.
Planets have two kinds of motion. One is rotation, where the planet spins on its axis (day). The
other type of motion is revolution, where it revolves around another body. The planet with the
smallest revolution is Mercury and the largest is Neptune.
Time it takes for a planet to rotate one complete spin on its axis is called period of rotation or
a day
Time it takes for a planet to complete one revolution around a star is called the period of
revolution
A period of revolution is equal to one year on that planet
On earth, it takes 365 ¼for the earth to make one revolution around the sun
Asteroids are rocky fragments, vary in size and are found in a belt between Jupiter and Mars,
known as the asteroid belt
Comets are made of ice, dust and gases - Icy dust balls
Meteoroids are small particles of rock and dust that move through the solar system
Meteors are sometimes called shooting stars, but they are not stars. If the meteor does
reach the earth’s surface, it is called a meteorite
Look over your Solar System Book in Book creator -Know planet sequence and our sister
planet.
Inner Planets – warmer, rocky
Mercury
Venus (our sister planet)
Earth
Mars
TEST ON THURSDAY, OCT. 1st
Outer Planets – colder, gas giants
Jupiter
Saturn
Uranus
Neptune
Know what factors make a world habitable and what happens when they are and aren’t just
right (Habitable Earth notes)
Temperature –
Water
Atmosphere
Energy
Nutrients
Study the “The U.S. Explores Space” Timeline and PowerPoint
Know the manned space program
1. Mercury (1958) (the first manned space program) – This project was the first manned
spaceflight program for the USA.
** The goals of the program were
A. to orbit a manned spacecraft around Earth;
B. investigate man's ability to function in space;
C. and recover both man and spacecraft safely.
Alan Shephard is the first American in space.
John Glenn- 1st American to orbit the Earth.
TEST ON THURSDAY, OCT. 1st
2. Gemini (1962) it was designed to extend the existing manned space flight program by
launching a two-man craft.
** The goals of the program were
A. to subject humans and equipment to up to two
weeks in space;
b. dock with orbiting vehicles;
c. and land at a pre-selected point.
3. Apollo (1961) **The goal of the program was to land a man on the moon.
Apollo- Early missions-tested equipment
Apollo-7 &9- Earth orbiting
Apollo- 8 &10- Went to the moon and back without landing
Apollo 11, 12, 14, 15, 16, 17- Six missions/12 men landed on
the moon
Apollo 13- Explosion in an oxygen tank nearly killed the three
astronauts. They only were able to orbit the moon but not land on the moon.
**Neil Armstrong - first man to walk on the moon (1969). His famous words were “One
small step for (a) man one giant leap for mankind.”
4. Skylab was the first American Space Station
5. International Space Station (ISS) (1998) - partnership of 16 countries;
*most of the equipment and parts from Russia and US
*crews have been living there since 2000
*ISS is usually made up of an international crew of
seven men and women who stay for 3-6 months at a time.
6. Know what STS stands for and the names of the 5 missions. Know they are reusable. Which
2 missions were deadly?
7. National Aeronautics and Space Administration (NASA)
TEST ON THURSDAY, OCT. 1st
8. Know the 8 accommodations (Ms. Feffer Listed) that humans need to make to be able to
live in space from space exploration notes.
9. Know the 3 things humans need to travel in space: water, food, oxygen – from habitable
earth notes
10. Know that there are 2 types of rockets – liquid propelled and solid propelled
