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
