Motion Graphs: TEKS 6.8D

To the teacher:• This CPO Science PowerPoint presentation is designed to guide you

through the process of presenting the lesson to your students. The presentation uses a 5-E teaching model: Engage, Explore, Explain, Elaborate, and Evaluate.

• The PowerPoint Slide notes indicate where you may want to bring in various lesson elements such as quizzes, readings, investigations, animations, and practice materials. Additional science background information is provided in the slide notes where appropriate. You can view these notes by selecting “View,” then “Normal.” You will see the notes pane at the bottom of the PowerPoint workspace. Additionally, the slide notes are available as a separate document, accessible from the lesson home page.

• The slides that follow are intended for classroom use.

Motion Graphs: TEKS 6.8D

Let’s take a road tripChristopher borrowed his mother’s car to run a quick errand. You

can use this motion graph to answer questions about his trip.

1. How far did Christopher’s car travel between points A and B? How much time did it take?

2. What is the speed of the car between points A and B? Is this when he is traveling fastest? How can you tell?

3. Describe the motion of the carbetween points B and C.

4. What does a negative slopemean?

Time to investigate!• Complete the lesson investigation:

– Position, Speed, and Time Graphs

Motion Graphs: TEKS 6.8D

Comparing the graphs

These two graphs show the motion for two objects.

• A position vs. time graph shows speed. The two objects are moving at a constant speed.

• A speed vs. time graphs shows the acceleration. Both objects have zero acceleration.

Motion Graphs: TEKS 6.8D

What else can you learn?• A steeper line ( = greater slope)

on a position vs. time graph means a faster speed.

• A speed vs. time graph can be used to find the distance the object has traveled.

Time for Practice!

• Which of the speed vs. time graphsmatches this position vs. time graph?

• Now, complete the lesson practice activity:– Analyzing Graphs of Motion with and without Numbers

• Hint: – You might want to review your lesson reading piece one

more time before trying the quiz.
