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

2. GRAPHING RULES - For each axis: equally spaced intervals - For each axis: numbering using multiples ex:1, 2, 3, 4, 54, 8, 12, 16, 20 2, 4, 6, 8, 105, 10, 15, 20, 25 3, 6, 9, 12, 156, 12, 18, 24, 30 - Label axes variable and units ex: 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 comparison Dependent/ Responding Variable you can not control; measure; data/information collected; y-axis Independent/Manipulating Variable you control; the factor that is changing (being tested); x-axis X- axis Y- axis 00 23 45 69 814 1020 1231 1446 1660 0 2 4 6 8 10 12 14 16 18 20 22 X X X X X X X X X extrapolate Prediction 0 3 5 9 14 20 31 46 60 greater than 60 ? WRONG!!!
