Objectives How can data be presented visually? 100S.ID.2.A.6 Create a simple graph Agenda IN: Why do we need maps? THROUGH: Map notes / White-boarding OUT: Mapping mistakes The Effect of Initial Water Temperature on Balloon Circumference Balloon Circumference (cm) 12 10 8 6 4 2 0 0 10 20 30 40 Initial Water Temperature (°C) 50 60 Graphing Number of Students 35 30 25 20 15 10 5 0 Not Proficient - 1 Partially Proficient - 2 Proficient - 3 Proficiency Level Advanced Proficient - 4 ADVANCED PROFICIENT (4) Graph meets ALL of the following criteria: 1. Correctly assign variables to the X and Y axes, labeling both axes and the variable plotted on each 2. Create a consistent, logical scale on both axes 3. Plot data accurately and legibly on the graph 4. Create a key that allows for the easy differentiation of different data series 5. Create an appropriate title for the graph GRAPHS 1.Variables 2. Scale 3. Plot Points 4. Key 5. Title Directions: Answer questions 1-16 with your partner to the best of your ability. 13. What is this thing called? 1.What is this called? 14 What does it tell us? 2.What does it tell us? 15. What do the best titles tell us? 3.Which variable is on this axis? 4.What does that thing in parentheses tell us? BONUS: Make a better title for this graph which actually tells us the conclusion of the graph. BONUS: Write the highest number on this axis (hint: it’s not 1,100) Station E 16. What is this called? 5. What are these two lines called? 17. What is important about the numbers at each line? 6. Which one is vertical (goes up and down)? 10. What is this called? 7. Which one is horizontal (goes side to side)? 8. Which one has the independent variable?_____ 9. Which one has the dependent variable?______ 11. What does it tell us? 12. Which variable is represented on this axis? BONUS: Here, 15 weeks pass between every dark line. Could the scientist have used a different interval (a different number of weeks between each line)? Scale What is a scale anyway? How do you figure out what the scale is? What is the scale on this graph’s: X-axis _____________ Y-Axis ____________ Common mistakes in creating a scale: 1. Just putting numbers from your table on every hash mark. 2. Making your scale too big or too small to be practical.

Plot points for 1 graph of your choice Norm Quiet voices (register 2) If one station is too crowded, move to another. Do not touch other people or their property Do not take down signs 5’P Exit Ticket Create a graph using the information from the table below.
