1. Opener 9/10/15  A study done by the Charlotte Sting of the WNBA showed that offensive rebounding increased the team’s average points per possession from.8 points to.9 points.  Question: In this example, what is the independent variable and what is the dependent variable? You have SIX MINUTES

2. Agenda  Classroom Constitution (10 minutes):  Norms Check: 8 th Period  Learning Target Check In (2 minutes):  Where we are, and where we are going  Graphing (40 minutes)  Setting up a Graph  Plotting Points  Line of Best Fit  Graphing Practice: Student Variables!  Cornell Notes: Variables (15 minutes)  Repetition!  Review Game: Zombie Grudge Ball (15 minutes)

3. Classroom Constitution Read Sign Accept

4. I can use a graph to model the relationship between two variables I can create a picture (a graph) that shows how two things (variables) are connected My graph will help me understand the connection, and make predictions about what might happen in the future.

5. 8 th Period: Calculate Averages  Do:  If you have not already shared data in your group, do that first  Then, calculate the AVERAGE bounce height for each drop height. Use the AVERAGE formula from your formulas page  Record averages in Data Table  You have FIVE MINUTES  WHEN DONE: Glue the T.A.L.K.S. handout onto PAGE

6. A Good Graph Needs to T.A.L.K.S to you What does that mean? Title Axes Label Key Scale

7. Graphing Ball Drop Data  DO:  Watch as Ziady models how to set up a graph that T.A.L.K.S.  Follow along, and set up your graph on the handout  Determine (x, y) points, and lot your points  After setting up the graph, you will have FIVE MINUTES to plot your points  When Done:  Work on “Analysis Question” #1 on the back of the handout

8. T itle What is the graph about? Your title should include both the independent and dependent variables

9. A xes Draw and Label X and Y axes. I.V. is graphed on X-axis and D.V. on Y-axis

10. L abels Each axis should be labeled with the name of the variable, and the units of measurement

11. K ey If there is more than one set of data on your graph, you will need a key

12. S cale What the number value of each box on the graph? You should set a scale that uses AS MUCH of the axes as possible

13. Graphing Ball Drop Data  DO:  Watch as Ziady models how to set up a graph that T.A.L.K.S.  Follow along, and set up your graph on the handout  Determine (x, y) points, and lot your points  After setting up the graph, you will have FIVE MINUTES to plot your points  When Done:  Work on “Analysis Question” #1 on the back of the handout

14. Line of Best Fit  DO:  Watch as Ziady models how to draw a line of best fit  Then, draw a line of best fit on your handout  You have THREE MINUTES  WHEN DONE:  Work on “Analysis Questions” #2 and #3 on back of graph handout

15. Graphing Practice: Height, Hands and Feet  DO:  Read the Questions and Tasks on the handout  Collect data about your classmates. Record in data table  Height and hand “wingspan” should be measured in centimeters.  Set up a graph that T.A.L.K.S. for ONE of the data sets:  Tables 1, 2, 4: Height vs. Shoe Size  Tables 5, 6, 7: Height vs. Hand “Wingspan”  Graph your data  You have 20 minutes  When Done: work on homework (second student graph + study time graph)

16. What do these graphs (MODELS!) tell us?

17. 4/3 This is your score for completing all parts the assignment. It does not tell you anything about the quality of your learning. This score goes in the Gradebook in the “Practice” category (20% of your grade) This score is an assessment of how well you learned the content or skill the assignment was teaching. This score does not go in the Gradebook. In this case, it tells you how well you used the text marking strategy BOTH SCORES are on a 1-4 scale. 2.5 is the minimum passing score

18. Notes: Variables in Science  DO :  Watch Ziady model setting up Cornell Notes, and set up your notes on PAGE 13  In the notes section, write a definition and an example of each of the following from the reading:  Variable  Independent Variable  Dependent Variable  You have 10 minutes  WHEN DONE:  Tape reading in to page 12  Add missing information  Highlight key words

19. Variables Notes  Variable : something whose value can change  Value : the number you get when you measure something  Example: the height of a high school student  Independent Variable: value does not directly depend on another variable  Example #1: how hard a soccer ball is kicked  Dependent Variable: value depends on the value of the independent variable  Example #1: the distance a soccer ball travels after it is kicked

20. Zombie Grudge Ball  Each table gets three X’s (Lives/Brains)  Questions shown on screen, then tables answer questions on whiteboard  10-30 seconds  Answer correctly?  Shoot a basket!  Make it—take an X off another table  Loose all your x’s?  U R Zombies (can’t win, but can knock X’s off)!  Team with most X’s left at end WINS and survives the Zombie Apocalypse

21. Which is faster, light or sound? 10 seconds Sound: 761 miles/hour Light 671 MILLION miles/hour

22. Identify the independent variable A student wants to know if eating breakfast helps students focus in class. She gets a group of 30 volunteers to skip breakfast for a week. Then, our student scientist measures the non-eating student’s focus in class, and compares it to the focus of 30 students who ate breakfast. 30 seconds

23. What letter DOES NOT appear on the periodic table? a.Q b.J c.Z d.F

24. What is the dependent variable in this graph? 30 seconds Rate of Basement Flooding

25. Whales are most closely related to A.Hippos B.Seals C.Pigs D.Aardvarks

26. What is missing from this graph? 30 seconds

27. Mr. Ziady’s middle name is... a.James b.Alexander c.Thomas d.Mr. Ziady doesn’t have a middle name

28. What could you add to this graph to show the relationship between temperature and visitors to the beach?

29. A frog can breathe through: a.Its lungs b.Its skin c.Both its lungs and skin d.Neither—frogs have gills

30. What is missing from this graph? 30 seconds
