Let’s Graph Unit 1
Why Graph? BRAINSTORM Spend 5 minutes writing down why graphing can be useful… What can we learn from the following graphs?
Some Important Terms To Know… All graphs must include 5 major parts Title: Be specific Independent Variable: What WE can control (X axis) The Dependent Variable: The change or outcome based on the independent variable (Y axis) The Scales for each variable: All data points must be used & YOU NEED TO USE THE WHOLE PAPER!!! The Legend: A short paragraph…kind of like the Cornell Notes Summary Key: You must ALWAYS create a key
Independent & Dependent Variables Independent variable is the one WE can control. Examples: Time, distance, length, temperature, etc Always goes on the X axis (bottom) Dependent variable DEPENDS on what happens when we change the independent variable Always goes on the Y axis (side) Example: WE control the depth, but the number of bubbles change. Did we control the number of bubbles?
Let’s Look… Number of Bubbles Depth in Meters I made some errors on purpose. Can you see them? How can we improve this graph?
