100
an object spinning on its axis
What is rotation?
100
this force attracts all objects toward each other. This force also makes things that go up come back down.
What is gravity?
100
changes in the Earth's water level that is cause by the moon's gravitational pull.
What are tides?
100
this model of the solar system has the sun at the center
What is heliocentric
100
This is the largest planet in our solar system. It also has a big red spot (which is a storm).
What is Jupiter?
200
the study of planets, stars and other objects in space
What is astronomy?
200
the amount of matter in an object.
What is mass?
200
the different shapes of the moon that you see from earth.
What are phases of the moon?
200
this scientist used the telescope to make discoveries that supported the heliocentric model.
Who is Galileo?
200
these planets are small, dense and rocky.
What are the inner planets (mercury, venus, earth, mars)?
300
the movement of one object around another
What is revolution?
300
these two factors determine the strength of gravity.
What is mass and distance?
300
when the moon passes directly between Earth and the sun.
What is a solar eclipse?
300
this scientist was able to figure out the arrangement of the planets and how they move around the sun.
Who is Copernicus?
300
some scientist debate if this planet is actually a planet.
What is pluto?
400
the reason we have winter, fall, spring and summer.
What is the Earth's tilted axis.
400
an object at rest will stay at rest, and an object in motion will stay in motion.
What is Newton's first law of motion.
400
this phase of the moon occurs when the sunlit side faces away from the Earth.
What is a new moon?
400
the orbit of each planet has this kind of shape.
What is an ellipse?
400
this planets axis of rotation is tilted at an angle of 90 degrees.
What is Uranus?
500
this occurs twice a year, when the sun is directly over the equator. It also means "equal night."
What is an equinox?
500
the two factors that combine to keep Earth in orbit around the sun and the moon in orbit around the Earth.
What are inertia and gravity?
500
the darkest part of the moons shadow.
What is an umbra?
500
this scientist found out that the obit of each planet is a ellipse.
Who is Kepler?
500
this is the reason for the Earth's temperature rise, also the reason why venus is hotter than mercury.
What is the greenhouse effect?
