___
memorize

structure of the sun from the middle outwards

Question Answer
orderheart, radiation zone, convection zone, photosphere, chromosphere and then crown
the heartThe place where nuclear fusion happens
radiation zoneIt covers the heart
convection zoneHot things go up and cold things fall
photospherethe surface of the sun. It is where all the light escapes
chromospherethe atmosphere of the sun. It glows around the sun
crowna more far away version of the chromosphere
memorize

THE SUN!!!!!!

Question Answer
solar eruptiongroup of gas and charged particles that boil over a solar stain
solar protuberance
explosion
explosion if gas that ranges to millions of kilometers into space
solar staina dark zone that is colder than the rest of the surface
starmassive accumulation of gas maintained by gravity that emits massive amounts of energy
solar windscharged particles that the sun releases when it emits light
solar massesthe measurement unit of mass using our sun
memorize

THE SUN!!!!!!! part 2

Question Answer
protostarsimportant concentration of gas and dust that leads to a star being born
white dwarfhappens when a small sun dies
neutron starappears when a big star is dead
nebulawhat’s left after a sun exploses
supernovaexplosion that happens when a very big star ends
big bangexploding mass and energy that started the universe
memorize

some definitions

Question Answer
astronomythe study of objects in space
celestial objectany object that is in space
universeeverything that exists
lunar eclipsethe moon is behind the earth
solar eclipsethe moon is in front of the sun. you can see the chromosphere of the sun.
space debristrash in space that orbits around the earth
electromagnetic rayenergy traveling at the speed of light emitted by matter
electromagnetic spectruma scale showing the different possible types of electromagnetic rays
a tidethe repeated rising and falling of the sea caused by sun or moon
memorize

planet

Question Answer
orbitclosed path around a body in space
orbit rayhalf of the the diameter of an orbit
rotation vs revolutionrotation is when a planet spins on itself revolution is how much times it completed its orbit
retrograde rotationwhen a planet rotates east to west
planetbig round celestial body that turns around a star
Polaristhe star that does not seem to circle around the sky at night it also points north
heliocentricthe correct model of the solar system
geocentricthe bad model of the solar system where earth is in the middle
memorize

planet 2

Question Answer
satelliteanything that orbits a planet
solar systemthe sun and all the planets around it
constellationsa group of stars and how you see them on earth
dwarf planeta planet too small to be a regular planet
lunar cyclethe phases of the moon
geosynchronous orbitits where something orbits the earth at a speed of the same speed it takes for earth to rotate causing the object to stay pointed at the same spot of the planet
3 effects of micro gravitymuscles are weak, plants don't grow well, humans get weak
memorize

galaxy

Question Answer
black holeextremely dense matter that attracts other matter at a force so strong, light cannot escape
galaxyenormous rotating group of gas dust and celestial objects
types of galaxieselliptic, spiral, lenticular and irregular
quasarssources of energy, extremely strong that can be detected by a radio telescope
types of telescopes areradio, optical, reflection and space
memorize

picture of galaxies here

celestial objects

Question Answer
cometspiece of ice and dust that travels a very large orbit around the sun
meteorsrocks that travel into earth but burn up in the atmosphere
meteoritesmeteors that hit the surface
meteoroidsasteroids that are smaller than 1 meter
asteroidschunks of rocks in space
memorize

science test

Question Answer
ohm's lawv = ir, i=v/r, r=v/r
paralel circuit vs series circuitseries is components connected at each other's end paralel is component connected beside each other
voltage and current in paralel vs seriesparalel; same voltage add current. series; add voltage same current
circuit with no resistanceshort circuit
a fusedestroys path if short circuited, one time use
disjoncteurdestroys path if short circuited, many time use
types of energy sourcesrenewable; can be used infinite times. non renewable; can be completly wasted
cost of electricitykilowatt/hour
one wattva
volt defpotential energy difference
amp defamount of electrons flowing
resistancehow difficult it is for electrons to flow
ac vs dcac alternates back and forth increasing the level of volt and current. dc just stays at same level of volt and current
circuits must havean electrical charge, some resistance, conductors, and a switch
types of batteriesrechargeable; made with dry solids. primary made with humid liquids
how a battery worksconverts chemical energy to electrical using copper inside and zinc outside and an electrolyte linking them two producing electricity
electrical energy mesured inwatts or joules
difference with static and dynamic electricitystatic; stays. dynamic; flows
joulesmesure de energy
wattsmesure de puissance par temps
efficencyenergy enters/exits *100
cost(watt/hour)* numberOfHours * numberOfKilowatts
lithiumrechargeable
alkalineprimary
