Metric System based on a base unit that corresponds to a certain kind of measurement Length = meter Volume = liter Mass = gram Density = grams per cm³ or g/cm³ Prefixes + base units make up the metric system Example: Centi + meter = Centimeter Kilo + liter = Kiloliter

PREFIXES are based on powers of 10. each prefix is a step either: 10 times larger (left) or 10 times smaller (right) examples Centimeters are 10 times LARGER than millimeters (1 step) 1 centimeter = 10 millimeters Hectometers are 10 times SMALLER than kilometers (1 step) 10 hectometers = 1 kilometer Kilo 1000 Hecto 100 Deca 10 meter liter gram g/cm³ Deci 1/10 Centi 1/100 Milli 1/1000

You do this no matter WHERE you begin on the scale Movement within the metric system is done by moving the DECIMAL POINT one place for each “step” desired You do this no matter WHERE you begin on the scale Example to right: move to right to change from meters to millimeters 1.0 meter = 1000.0 millimeters Example to left: move to Left to change from liters to kiloliters 1.0 meters = .001 kilometers kilo hecto deca meter liter gram g/cm³ deci centi milli

Metric System Summary Base units in the metric system are meter, liter, gram Metric system is based on powers of 10 For conversions within the metric system, each “step” is 1 decimal place to the right or left converting to the right, moves the decimal to the right and converting to the left moves the decimal to the left

GRAPHING- 3 Types of Graphs -BAR GRAPHS -LINE GRAPHS -PIE CHARTS

LINE GRAPHS -A type of graph that highlights trends by drawing connecting lines BETWEEN data points. What Every Line Graph should have! -Axes (x,y) labeled -equal intervals -origin -units -title -data points -key (if needed for multiple variables)

-key (if needed for multiple variables) BAR GRAPH a type of graph where different values are represented by rectangular bars. What Every Bar Graph should have! -Axes (x,y) labeled -equal intervals -origin -units -title -data points -key (if needed for multiple variables)

PIE CHART A type of graph where percentage values are represented as proportionally-sized slices of a pie. What does every Pie Chart Need Title Explanation of sections (pie pieces) Key if necessary Different colors or patterns Circle divided in percentages
