Materials: Catalyst sheet, notes sheet • Catalyst (5 min): Ms. Beck wants to see if giving students more tutoring before tests would increase the average GPA at Forest Park High School. She decides to run an experiment, but needs your help in designing it: (a) State a hypothesis for Ms. Beck (If……then……) (b) Describe one way the experimental group should be treated differently than the control. (c) Identify the dependent variable in Ms. Beck’s experiment. (d) If the data that Ms. Beck collects fails to support her hypothesis, is her experiment invalid? Justify your answer.

Elite Eight Trait Check-Up 1. Respect the Threshold 1. Everyone on time? 2. Silent for First Five? 2. Be Prepared (2 min) 1. Seated 2. Have materials 3. Working on catalyst

Class Motto If there is a problem, We look for a solution. If there is a better way, We find it. If we need help, We ask. If a teammate needs help, We give.

Announcements • First Star Quiz Wednesday! Over the Scientific Method • Class Manager Announcements! • Tardy Policy – 1 st : warning – 2 nd : detention and parent phone call – 3 rd : referral and 1 day detention – 4 th : referral and 2 days detention – 5 th : referral and 1 day Saturday detention

Foldable Homework Turn-in Rates • • • 1 st = 57% 2 nd = 65% 4 th = 78% 5 th = 45% 6 th = 35% 7 th = 56% • This is not going to get us to our goal! We need to work towards 100% turn in rate if we are going to be SUCCESSFUL!

Objectives • I can use given data to create line graphs and a bar graphs • I can analyze a graph and identify its trends

Head your paper Notes 1. 2: Graphing

Notes: Why are graphs important? • Graphs help represent data visually • Graphs help scientists notice trends or patterns in their data

Graphing Notes Steps for Making Graphs: 1. Create a descriptive title (x axis vs. y axis) 2. Dependent variable is plotted on the y-axis (vertical/ up & down) 3. Independent variable is plotted on the x-axis (horizontal/ across) 4. Use an appropriate scale (Each box is worth the same amount!) 5. Bar graphs: Draw a bar reflecting the data 6. Line graphs: Plot data points, circle and connect

Practice Problem 1 create a chart to organize the following data from an experiment testing the effects of temperature on the # of tomatoes a tomato plant produces: 1. At 40° plants produced 2 tomatoes, At 50° plants produced 7 tomatoes, At 65° plants produced 8 tomatoes, At 70° plants produced 13 tomatoes Temperature (degrees F) Number of Tomatoes

Bar Graph Temperature Number of (degrees F) Tomatoes 40 2 50 7 65 8 70 13

Line Graph Temperature Number of (degrees F) Tomatoes 40 2 50 7 65 8 70 13

Group Activity • Get out one piece of notebook paper group • Write every group members’ name at top and class period • As a group, identify what is wrong with each student’s graph • Explain what each student should have done instead • After each graph, have your groups RUNNER bring your paper to me to check and give approval for you to move on • FIRST GROUP TO GET ALL 5 CORRECT WINS 2 tickets each!

Closing • Homework: Any classwork you didn’t finish is homework – Due Tomorrow • First Star Quiz on Wednesday! (Scientific Method) • What are 2 graphs we learned about today? • What is plotted on the x axis? • What is plotted on the y axis? • Why is it important to report scientific findings visually? • What do graphs help us discover about our data?
