### Cards for chapter 5, 6th grade science- Malia Nelson -Abeka curriculum

Sir Isaac Newton The scientist who discovered the law of universal gravitation and the sunlight is a combination of many colors, developed the reflecting telescope, and discover the three laws of motion.
Visible spectrum The color sequence red, orange, yellow, green, blue, and violet visible when white light is passed through a prism. (Roy GBV)
wave A movement of energy from one place to another.
Trough The low point of a wave.
Oscillation A back and forth motion of a wave, that repeatedly follows the same path.
Crest The high point of a wave.
Medium (Plural:Media) The term for whatever carries a wave.
Magnetic field The area surrounding a magnet in which the force of magnetism affects other objects.
Electric field A region in which certain objects may be attracted or repelled by an electric force as in "static electricity."
Electromagnetic wave A wave consisting of an electric field and a magnetic field vibrating at right angles to each other. Electromagnetic waves do not need a medium. Also the type of wave that is light
James Clark Maxwell The man who discovered electromagnetic waves and realized that light is a type of electromagnetic wave.
Electromagnetic waves travel how fast? And what is this speed referred to as? 186,000 miles per second. The speed of light.
Frequency How fast a wave oscillates.
Wavelength The length of one complete wave or cycle of oscillation (Measured from crest to crest or trough to trough.)
Electromagnetic spectrum An arrangement of electromagnetic waves according to frequency and wave-length.
Telescope A device used to make distant objects appear clearer, brighter, or closer.
Galileo The first astronomer to make extensive use of a telescope to study the heavens.
Refracting telescope A type of telescope that uses lenses to gather light and form an image.
Reflecting telescope A type of telescope that uses mirrors to produce and image.
Reflection The turning back or turning aside of any wave when it hits an obstacle.
Refraction The bending of an waves's direction at the boundary between two wave media.
What is the simplest possible telescope? A refracting telescope, a telescope made of two convex lenses.
Who developed the reflecting telescope? Sir Isaac Newton
Hubble space telescope A reflecting telescope with an 8-foot wide main mirror launched into orbit around the earth in 1990.
Spectroscope A special device that can split light into a spectrum for analysis. Also the device that is used to discover what distant objects are made of
Radio telscopes An instrument that collects radio waves from space and allows us to study the heaven using portions of the electromagnetic spectrum that are invisible to the human eye.
Pulsars A star that produces rapid bursts of radio waves. Also thought to be the cores of exploded stars
Astronauts A person who journeys into space. (specifically Americans, Russian's people were called cosmonauts) (who knew!)
Robert H. Goddard An American scientist who built and launched the first liquid fueled rocket; called "The Father of Modern Rocketry."
Wernher von braun A scientist who helped the United States become the world leader in space exploration; generally considered to be the most knowledgeable astronomical engineer in the world until his death.
Satellite Any object that orbits a larger object.
What does the first law of motion state? Any object in motion will continue moving in the same direction and at the same speed unless an outside force acts upon it.
Explorer 1 The first satellite launched by the United States, in January 1958
Sputnik 1 A Russian satellite launched in 1957 that was the first artificial object to orbit the earth.
What happens if you launch a satellite to quickly? If you launch a satellite to fast it will orbit farther and farther from the earth as it increased its speed and eventually escape all together.
Yuri Gagarin The first person to travel in space.
Alan Shepard America's first person in space.
John Glenn The first American to orbit the earth.
Valentina Tereshkova Valentina Tereshkova was the first women to fly in space.
Apollo 11 The first space mission to actually land on the moon.
Neil Armstrong The first person to set foot on the moon.
Space stations A structure in space in which people can live and work for weeks or months at a time.
Skylab The United States' first space station.
Mir The first space stations that had the ability to have extra "rooms" (or modules) could be added after it was launched.
International Space Station A space station that sixteen nations worked together to build.
Space shuttle An american spacecraft, first launched 1981, that was the first space craft designed to be reused.
Communications satellites Satellites that relay telephone conversations, transmits television broadcasts, and make radios work
Geostationary orbits An orbit in which a satellite follows the direction of the earth's rotation in such a sway that it stays in the same location in the sky.
Weather satellites Provide forecasters with photographs of the cloud patterns that cover the globe, allowing them to study the weather around the world.
Polar orbits An orbit in which a satellite travels perpendicular to the equator, passing over the polar regions as it circles the earth.
Navigational satellites A navigational is a satellite used to tell you where you are, such as the GPS.
GPS The most famous network navigational satellites is the GPS. (Global Positioning System) These satellites can pin point its own position the earth within a few yards, with the help of GPS satellites.
Earth resources satellite May perform a variety of functions, such as making maps, forecasting crop production, spotting forest fires, and surveying cities. These satellites pretty much are "everything" satellites.
Astronomical satellite Satellites that are designed to study the heavens
Space probe A unmanned spacecraft that is launched specifically to explore the unknown.
Name the inner and outer planets (in order.) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. (Pluto is no longer considered to be a planet.)
Mercury The closest planet to the sun; the speediest planet
Venus The second planet away from the sun and hottest planet in our solar system; the brightest object in the night sky except for the moon; called the morning star and evening star.
Year The period in which the earth revolves around the sun; 365 1/4 days.
Day The amount of time it takes for the earth to rotate once on its axis.
Months The amount of time it takes for the moon to pass from new to new again.
Weeks Is determined not by the the movement of the earth or/and moon, but by God.
Mars The forth planet from the sun; called the red planet.
Phobos and Deimos Mars' two asteroid-like moons. Deimos is the smaller of the two.
Jupiter The fifth planet form the sun and the largest planet in our solar system
Ganymede The largest moon in our solar system.
Europa Due to Europa's icy surface Jupiter's moon is icy and smooth.
Callisto one of Jupiter's moons, this icy "satellite" is covered with craters.
Io Red-orange Io has the first active volcano ever discovered on another world; This moon of Jupiter's is even colored from the sulfur and other chemicals spewed by its many volcanoes!
Saturn The sixth planet for the sun; known for its glorious rings; has at least 30 moons.
Titan Saturn's largest moon; this moon has it's own atmosphere.
Uranus The seventh planet from the sun, noted for being turned on its side.
William and Caroline Herschel The astronomers who discovered Uranus.
Neptune The eighth planet from the sun.
Pluto The ninth planet from the sun; the outer most planet in the soar system and the smallest planet.
How many moons is Neptune known to have? Eight
Charon Pluto's own moon!
What happens if you launch a satellite to slowly? If you launch a satellite too slowly the earth's gravity will pull it downward causing it to burn up in the atmosphere.
Triton Neptune's largest moon
Great red spot A gigantic rotating storm on Jupiter twice as wide as the earth.
Mercury (Program) A series of manned U.S space flights during the early 1960's. (this was the program to launch a man in space) (who knew!)
