Solar System Notes Measuring Up! Science Lesson 25 Stars
Slide 3
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.
Slide 4
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.
Slide 5
Measuring Up! Guided Instruction Read page 169 to 170 in the MU
book.
Slide 6
Guided Questions About how many galaxies are in the universe.
There are about 130 billion galaxies. What are satellites?
Satellites are solid bodies that orbit the planets.

Slide 10
Spatial Intelligence Color the planets in your notes. Sketch
and label the Asteroid Belt. Label the Inner Planets and Outer
Planets.

book.
Slide 12
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.
Slide 13
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.
