Science Lesson 25
Stars
California Standards
8.4.c: Students know how to use astronomical units
and light years as measures of distance between
the Sun, stars, and Earth.
8.4.d: Students know that stars are the source of light
for all bright objects in outer space and that the
Moon and planets shine by reflected sunlight, not
their own light.
8.4.e: Students know the appearance, general
composition, relative position and size, and motion
of objects in the solar system, including planets,
planetary satellites, comets, and asteroids.
Language of the Discipline
 The
solar system is the Sun and the objects
that orbit it, such as planets.
 Satellites are the solid bodies that orbit a
planet.
 The inner planets are the four solid planets
closest to the Sun.
 The outer planets are the four gaseous
planets after the inner planets.

Guided Instruction
Read page 171and
172 in the MU book.
Guided Questions
 Name
the four inner planets.
 Mercury, Venus, Earth, Mars
 Name
the four outer planets.
 Jupiter, Saturn, Uranus, Neptune.
 What
is the surface of Pluto like?
 Pluto is small, dark, cold, and rocky.
 What
is the mood made of?
 The moon is made of mostly silicate rocks.
More Guided Questions
 List
the objects in the solar system that are visible
from Earth. Include what enables them to be
visible from Earth.
 The Sun and stars give off light, so they are visible
from Earth. The planets, moons, and comets are
visible because they reflect light.
 Compare the makeup of the inner planets to the
outer planets.
 The inner planets are mostly solid and are made of
silicate rocks. The outer planets are large balls of
gas, made mostly of hydrogen and helium, with
small solid cores made of metal or rock.
