I can use a graph to model the relationship between two variables Today’s Supporting Target d. I can draw a LINE OF BEST FIT on my graph Highlight and date this learning target on page 7

Graphing Practice: Height, Hands and Feet DO: Review our data together THINK: What do these graphs (MODELS) tell us? PAIR: With table partner TIME: 1 minute SHARE: Out with class

Graphing Ball Drop Graph REVIEW CLASSWORK: With table partner DISCUSS: Your answers for #1, #2, and #3 on the back of the graph CAREFUL NOT TO COPY TIME: 4 MINUTES WHEN DONE: Be ready to share you answers and tape into page 13 (we will revisit it later in class)

What do these graphs (MODELS!) tell us?

Notes: Variables in Science DO: ◦ Watch Ms. Myriah Day model setting up Cornell Notes, and set up your notes on PAGE 12 ◦ In the notes section, write a definition and an example of each of the following from the reading: ◦ Variable ◦ Independent Variable ◦ Dependent Variable TIME: 11 minutes WHEN DONE: ◦ Tape reading in to page 11 ◦ Add missing information ◦ Highlight key words in your notes

Variables Notes Variable: A value that 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 ◦ “I” can change it. ◦ Example: how hard a soccer ball is kicked Dependent Variable: value depends on the value of the independent variable ◦ Example: the distance a soccer ball travels after it is kicked

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

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

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

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

What is the dependent variable in this graph? Rate of Basement Flooding 15 seconds

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

What is missing from this graph? 30 seconds

Ms. Myriah Day’s middle name is. . . a. b. c. d. Jane Janine Jeannie Ms. Myriah Day doesn’t have a middle name

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

What is missing from this graph? 30 seconds

Using the Model to Determine the Pattern SET UP: Cornell Notes on page 14 Watch how I model it TOPIC: Graphs as Models ESSENTIAL QUESTIONS: What can a graph tell us that the data we collected doesn’t? What pattern is shown in this set of data?

9/15/15 Graphs as Models Essential Question (EQ) What can a graph tell us that the data we collected doesn’t? What pattern is shown in this set of data? A graph is a model of reality Models simulate the world Models help us understand reality A graph can be used to find values for the dependent variable that were NOT measured Ex: we can find bounce heights for drop heights we didn’t measure

9/15/15 Graphs as Models Essential Question (EQ) What can a graph tell us that the data we collected doesn’t? What pattern is shown in this set of data? FILL IN THE VALUES FOR YOUR BOUNCE HEIGHTS Down the page What are the bounce heights? What happened to the DV when you double the IV? Drop Heights IV: 10 cm 20 cm DV: The DV also doubled. 40 cm 80 cm

9/15/15 Graphs as Models Essential Question (EQ) What can a graph tell us that the data we collected doesn’t? What pattern is shown in this set of data? Down the page In a directly proportional relationship, when you double the x value, the y value doubles too.

Spring Stretch Investigation GLUE: The two handouts into the next two blank pages (probably pages 15 and 16) ◦ Research Questions: left side ◦ Procedure and Data Table: right Side TIME: 3 MINUTES WHEN DONE: READ the research questions. Do you understand why you are doing this?

Research Questions • How does increasing the mass hung on the end of a spring affect how far the spring stretches? • What is the relationship between the variables “spring stretch” and “mass”?

You will use this model to set up a safe (and exciting) bungee jump for a RAW EGG. SAFE: DOESN’T SMASH THE EGG EXCITING: GETS AS CLOSE TO GROUND AS POSSIBLE

Spring Investigation Data Collection DO: Identify variables Make a written and visual hypothesis Gather materials and collect data TIME: 22 MINUTES WHEN DONE: ◦ Graph your data, using the T. A. L. K. S. criteria Call Ms. Myriah Day over when ALL group members have complete these steps
