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.
4 2 x 100 2x x = = = 200 Proportions Concept

Scale Factor The number that is multiplied to make objects the same size. 364 x x = x =
Terms to Know What is Diameter? The distance across a center point of a circle What is radius? Half of a surface starting at the center point of a circle (1/2 diameter) Formula to find the area of a circle? 2 r Diameter Radius

Will you be the next NASA astronaut, engineer, or scientist?
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 For more info view the Mars DLN show
