Remember: Answer questions so it’s clear what you are answering Warm-up Remember: Answer questions so it’s clear what you are answering What is the rule on coming to class and being on time? What is the late-work policy in this class? What is the electronics policy at LHS? List 4 things you need to bring with you to class everyday?

Graphing What is a Graph? Way of visually representing the relationship between two or more variables. WHAT THE ?!?! Drawing that shows how two different things affect each other. Ordered Pairs (X,Y) EX: (-1,3) , (2,5) , (0,0)

Graphs & Tables TABLE: WHY Graphs? A chart that shows ordered pairs. Easy to see relationships.

Different Graphs Bar Graph Pie Chart Line Graph Comparing categories Comparing parts of a whole Line Graph Comparing 2 things that change together (most common in science!)

Lab #1 – “Introduction to Graphing Activity” Measuring in Metrics: Meter, cm, mm INCHES

LAB #1 Vocabulary Review: “Average” = Middle value “Percent” = “per” + “cent” = for every 100 Average = __(Sum of values)__ Total # of Values Percent = ___(Value Given)___ x 100 (Max. Value Possible)
