Jamal is making a model of the universe using common objects to represent the universe, the Milky Way, the solar system and the Sun. He chooses a grape, his classroom, a tennis ball and an extra-large pizza to represent objects in his model. He decides to use the pizza to
represent the Sun. Why is Jamal’s decision not the best choice?
The grape is the better choice since it is the smallest of the selected objects.
The classroom should be used since it is large like the Sun.
The tennis ball is the better choice due to its yellow color
The pizza is the better choice because of its shape.

The Hubble Space Telescope recently provided scientists with an image and data related to an object in space that is composed of billions of stars of different colors and sizes and enough gas and dust
to make billions more stars.
What conclusion can be drawn from this information?
The image is of a distant solar system because of the presence of at least one star.
The image is of galaxy because of the presence of billions of stars, gas
and dust.
The image is of the entire universe, because of the presence of stars, gas, and dust
The image is of the formation of a new planet as indicated by the presence of dust.

In Science class, students were asked to arrange a group of astronomical bodies from largest to smallest. Four of the lists created
are shown below.After reading all of the groups lists, the teacher stated that no group had the accurate order. The students began to argue about how to correct their lists. Which statement best states how a group could change their list to produce the correct sequence of objects?
Group 1: Since Jupiter is larger than a main sequence star, these two objects should switch places
Group 3: A nebula is smaller than a galaxy and a main sequence star so it needs to be moved above Jupiter.
Group 4: Jupiter is smaller than a galaxy and by switching these two objects the list becomes correctly ordered.
Group 2: Objects are listed from smallest to largest so the list just needs to be flipped.

Which statement most accurately describes the planets?
The outer planets are relatively the same distances from each other
The inner planets are closer to each other than the outer planets.
The inner planets have faster orbits since they are farther from the Sun.
The outer planets have less gravitational pull since they are closer together.

The astronomical objects should be listed in order from largest and smallest. One group is not. Which group is NOT listed in the correct order?
Group 1: Sun, Jupiter, Earth, Mercury, Moon
Group 2: Milky Way Galaxy, Universe, Solar System, Mars
Group 3: Sun, Earth, Moon, Meteorite
Group 4: Sun, Earth, Moon, Comet
Group 2 is incorrect because the Milky Way is smaller than the Universe
Group 4 is incorrect because the moon is larger than Earth.
Group 1 is incorrect because the Moon is larger than Mercury.
Group 3 is incorrect because a meteorite should be listed between the Sun and Earth.
