22. Bower hierarchical relationships

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.

Students were asked to sort astronomical objects by similarities. One group sorted the objects as shown in the table below.How did the students most likely justify sorting the objects as they did?

• The objects in SET 1 have rocky surfaces, while the objects in SET 2 contain gases.

• The objects in SET 1 are all planets while SET 2 objects all orbit the Sun.

• The objects in SET 1 are all part of the Milky Way galaxy, while SET 2 objects are equal distances apart.

• The objects in SET 1 are located the same distance from the Sun, whereas, the objects in SET 2 are all of similar sizes.

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.

grouping of astronomical bodies was posted on the classroom whiteboard. The teacher asked the students to determine if the objects were related or unrelated and to justify their answer. Which response would the teacher most likely expect to see?

Galaxy Star Nebula

• Related: All three have a connection to stars

• Unrelated: Nebulas are part of a galaxy while stars are not.

• Related: All three are found in our solar system

• Unrelated: Nebulas are not found in the universe.

The points labeled on the chart below represent the approximate size of Earth, the Milky Way, the Moon, and the Sun. The approximate size of the Solar System is also shown.Which point on the chart best represents the approximate size of the Sun?

• w

• y

• x

• z
