Mastering Graphing Techniques: An Exercise in Data Interpretation
This exercise guides students in proper graphing techniques, focusing on distance vs. time, speed vs. time, and acceleration vs. time. Students will learn to record data, create charts, and interpret graph results. By following specific instructions, they will analyze patterns and draw conclusions about motion. Each section builds understanding, from creating data charts to graphing speed and acceleration. As a summative task, students will answer critical questions regarding graph interpretations to solidify their comprehension of graphing principles.

Graphing Exercise Swbat: use proper graphing techniques to graph data Swbat: interpret data from a graph and draw conclusions about the information
Instructions Get a blank piece of paper. Fold it Hotdog and Hamburger to make even quarters. Mark the lines.
Continued… • Number each quarter of the paper starting in the top left moving clockwise. • Label each section as follows: • 1. Data Chart • 2. Distance Vs. Time • 3. Speed Vs. Time • 4. Acceleration Vs. Time 2 1 4 3
Section 1 Copy the data from the slide into a chart in this section of your paper. It should have 2 columns. One for time and one for distance.
Section 2 Draw a graph that relates distance and time. Remember we are controlling what time we take measurements and the recording the response. (DRY MIX) Distance in meters Time in Seconds
Section 3 Remember that speed=distance/time. And that we only need to be concerned with the change in time when we look at speed. Calculate the speed the object is traveling each second and make a graph that relates speed (which we are calculating) and time (which we are choosing)(DRY MIX).
Section 4 Acceleration is changes in velocity. Using the previous graph as a data source, draw a graph that relates acceleration (calculated) and time (which was chosen.
Distance vs. Time 35 Distance in Meters 30 25 20 15 10 5 Time in Seconds 5 30 10 25
Speed vs. Time 3 Speed in m/s 2 1 30 Time in Seconds 5 10 25
Acceleration vs. Time Acceleration in m/s/s 3 2 1 5 30 10 25 -1 -2 -3 Time in Seconds
On the Back… • Be sure you have your name at the top!!!! • Answer the following questions: • 1. What will a Distance Vs. Time graph look like if the object is standing still? • 2. What is happening if the same line was vertical? • 3. describe the lines on an Acceleration Vs. Time Graph when the object is sitting still. Moving at a constant speed of 3 m/s. • 4. Which direction will the line go in a Distance Vs. Time graph if the object is slowing down but still traveling forward?
