Graphing

There are 3 types of graphs 1. Line Graph 2. Bar Graph 3. Circle or Pie Graph

Definitions Independent Variable – What is being changed (amount of water) Dependent Variable – What you observe (change in height) Controlled Variable – What you keep the same (cruise control)

All graphs must include: Title Name Label each axis with units X-axis – Where the independent variable goes Generally time (months, days, years, hours , etc) Y-axis – Where the dependent variable goes Mass, temperature, weight, pounds, etc. Key – If you have multiple lines or bars
