Aim: How do we construct and analyze a line graph? OBJ: Given activity sheet SWBAT construct and analyze a line graph with 70% accuracy.

DN: Read over Graphing Rules

ACT: Review Graphing RulesWork on Graph Interpretation Activity Sheet

HW: Complete Graph Interpretation Activity Sheet; Work on Test 1 Review Packet; Matter Exam, Tuesday, 9/30.

GRAPHING RULES- For each axis: equally spaced intervals - For each axis: numbering using multiplesex: 1, 2, 3, 4, 5 4, 8, 12, 16, 20

2, 4, 6, 8, 10 5, 10, 15, 20, 253, 6, 9, 12, 15 6, 12, 18, 24, 30

- Label axesvariable and unitsex: Time (minutes), Distance (meter)- Connect data points making a line- Title for graph Constant – equipment that remains the same during an experiment.

Control - a set-up in an experiment in which

the factor shows no change; used for comparisonDependent/ Responding Variableyou can not control; measure; data/informationcollected; y-axisIndependent/Manipulating Variable

you control; the factor that
