Standard: Show Content Tip
5a Students know the Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium.
Holistic Rating: Limited coverage of this standard.
| Pages B17, B30-B37, B39, B56-B57, and B65 provide limited coverage of the standard. |
Aspects that do not help student learning:
In the illustration of the solar system (pages B34-B35), some of the planets are shown as being bigger as the sun. Text explains that the planets are drawn much bigger than they should be compared to the size of their orbits, but does not explain how much smaller they are than the sun. The text is very limited in its explanation of how massive the sun is (sun contains 99.8% of the mass of the solar system). A few dispersed sentences say that the sun has the most mass.
Text mentions in several different contexts that the sun contains hydrogen and helium, but it does not clearly explain that the sun is composed primarily of hydrogen and helium. Text also says that the sun is an average star, but the illustration on page B57 can be readily misinterpreted as showing that the sun is an unusually small star. Text describes and highlights many extraneous concepts.
Page B17 mistakenly states that until very recently, scientists thought there were only nine planets in the universe.
