Cards for chapter 5, 6th grade science- Malia Nelson -Abeka curriculum
| Question | Answer |
|---|---|
| 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. |

| 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!) |
