1Astronomy Common Assessment Review and Learning Targets
2We are learning to: describe how objects in the solar system are in regular and predictable motions that explain days, years, and seasons.We are looking for: description of:Days- Earth rotates on its axis every 24 hoursYears-Earth revolves around the sun daysSeasons-Earth revolves around the sun as the Earth is tilted on its axis
3Why do we have night and day? Earth’s rotationEarth’s revolutionTilt of the Earth on its axisI need Help!
4What causes Earth to experience different seasons? It rotates on its axis while it revolves around the sunIt revolves on its axis while it rotates around the sunIt is tilted while it rotates around the sun.It is tilted while it revolves around the sun.I need help!
5If the Earth’s Revolution was slower, we would experience Longer daysShorter daysLonger yearsShorter yearsI need help!
6Of the following, which does not affect seasons? Earth is tilted 23.5 degreesThe Earth revolves around the sunThe Earth’s distance from the sunI need help!
7We are learning to: describe how objects in the solar system are in regular and predictable motions that explain phases (moon cycles), eclipses, tides We are looking for: a description of -Phases-moon revolves around the Earth approximately once a month -Eclipse-are random predictable; one object moves in front of another object in relation to the position of the sun -Tides-high tide occurs approximately twice a day due to the gravitational pull of the moon
8Which phase occurs when the moon is in between the Earth and the sun? Full moonNew moon1st Quarter moon3rd quarter moon
9What causes us to see different phases of the moon? Light refracts off of the surface of the moon.The moon rotates around the Earth.We see different perspectives of the moon.I need help!
10What is the main cause of tides? The gravitational pull of the moonThe gravitational pull of the sunThe gravitational pull of the EarthI need help!
11Neap Tide Solar Eclipse Lunar Eclipse Seasonal Change If the sun, moon, and Earth are perfectly aligned (as pictured), what event will occur on Earth?Neap TideSolar EclipseLunar EclipseSeasonal Change
12When studying a solar eclipse, which would be a proper method of viewing the sun? Wear sunglassesUse a telescopeUse a magnifying glassUse filters that are specifically designed to view eclipsesI need help!
13We are learning to: explain that gravitational force determines motions in the solar system and keeps the planets in orbit around the sun. We are looking for: explanation that *All objects in the solar system have gravity. *Sun has the greatest mass, thus has the greatest gravitational pull within our solar system. *Since planets have inertia, they do not get pulled into the sun. *Gravity keeps the planets in orbit.
14What is an object’s resistance to a change in motion? GravityInertiaMassFrictionI need help!
15It will fly off into space. It will hit the nearest planet. Predict what would happen if Earth stopped its forward motion around the sun?It will fly off into space.It will hit the nearest planet.It will get pulled into the sun.It will continue to revolve.12345678910111213141516171819202122
16What keeps planets revolving around the sun? The sun’s gravitational pull.The planet’s mass.The planet’s magnetic field.The Sun’s inertia.I need help!12345678910111213141516171819202122
17We are learning to: *Compare the composition and orbits of comets and asteroids with that of Earth. We are looking for: Composition of comets, asteroids, and Earth 1. Earth is composed of rock with many layers and has a core of dense metal 2.Comets are composed of ice and dust (dirty snowball) 3. Asteroids are composed of chunks of solid rock with heavy metal Orbits of comets, asteroids, and Earth’s 1. Earth’s orbit is elliptical 2. Comet’s orbit is elongated and elliptical 3. Asteroids are irregularly shaped and orbit in the asteroid belt
18We are learning to: Describe the effect that asteroids or meteoroids have when traveling through space and entering planetary atmospheres.We are looking for:Asteroids are large rocky objects that orbit the sun. If they hit the Earth the impact could be catastrophic.Meteorites are small rocky objects hit the Earth all the time and do not cause much damage.A rock changes its classification based on its location:Meteoroid – rock located in outer spaceMeteor – rock burning up in the Earth’s atmosphere (Shooting Star/Meteor Shower)Meteorite – rock that hits the ground
19An icy object that has an elongated orbit around the sun is referred to as a(n)…. AsteroidCometMeteorMeteoriteI don’t know!12345678910111213141516171819202122
20The flash of light produced when a meteoroid passes through the Earth’s atmosphere is a(n) AsteroidCometMeteorMeteoriteI don’t know!12345678910111213141516171819202122
21Why does a meteoroid create a streak of light when entering the Earth’s atmosphere? Light from the sun is reflected off the surface of eachEnergy is released from the objectsLightning is produced from these objectsLight is a result of friction from the gasses in the atmosphereI don’t know!12345678910111213141516171819202122
22Which of the following applies to meteoroids and asteroids. They are similar in size.They are rocky and/or metallic.They are composed of frozen gases, ice, and dust.They orbit the sun in highly elliptical patterns.I don’t know!12345678910111213141516171819202122
23Which of the following objects would cause the most damage if it hit the Earth? AsteroidMeteoroidMeteoriteMeteorI don’t know!
24We are learning to: identify and describe telescopes, probes, satellites, and space crafts We are looking for: telescope- refracting, reflecting, and radio are used to view distant objects probe-machines sent to other locations in the solar system and are used to investigate/explore satellite-orbits around the earth or other planets and are used to take photos and collect data space craft-mode of transportation to send humans to locations in the solar system;
