Terms to Know

• What are ratios/proportions?
• the relationship/comparison in quantity,
  amount, or
• size between two or more things
• Example
• If you have a classroom with 4 girls and 2
  boys
• The ratio of girls to boys is 4/2.
• The ratio of boys to girls is 2/4.

Mars

• Mars is smaller and colder than Earth
• It has a thin atmosphere and polar ice caps, and
  dry riverbeds crisscross its surface.
• There are no signs of great civilizations past or
  present on its red surface.
• In August 1996, though, scientists announced the
  discovery of possible microscopic fossils in a
  meteorite from Mars.
• Trace elements prove that it came from Mars
