This document discusses using graphs to represent motion. It provides an example of using a distance-time graph to show a student's displacement traveling to and from school. Key points on the graph are labeled and questions are asked about what each point represents and what parts of the graph indicate characteristics of the student's motion, like periods of waiting versus different walking speeds. The document aims to help students learn how scientists use graphs to visualize and analyze motion.

Q1. What do we mean in science when we use the word Motion? Q2. What are some key characteristics of motion that we can measure? Q3. What is a graph in science and why are there commonly two axes on graphs.?
Question 1. What do we mean in science when we use the word Motion? When something is moving.
Time Distance Direction Speed Velocity acceleration Q2. What are some key characteristics of motion that we can measure?
A graph is a visual way to show the relationships between two aspects of a situation being analyzed, such as showing how distance relates to time. Q3. What is a graph in science and why are there commonly two axes on graphs.?
Lesson-15-Lets-Scientifically-Analyze-Motion.pptx
Lesson Purpose and Intention The lesson is about learning how scientists represent motion in tables and graphs and use this to visualize motion in a way that allows us to analyze it and to make predictions based on the analysis. Graphs help to identify patterns and make connections that develop our thinking about the associations between the things we are measuring (the variables).

Anas displacement to and from school We can use a graph to represent Anas displacement from her house to school in the morning, and then from her school to her house in the afternoon after school finishes. Please recall from Lesson 14 that, in the mornings, Ana walks from Point A to Point B and that takes 6 minutes. She then waits 2 minutes at Point B for her friend Bea to get ready. Then Ana and Bea take 3 minutes to walk together from Point B to the school at Point C.
After school, Ana walks directly from her school to her house on North Street. The following is a graph that represents Anas walk to and from her house to school. Some important points are labeled 1, 2, 3, 4, and 5 on the plotted line.

Q1. What does point 1 on the graph represent? Q2. Which part of the plotted line on the graph represents Anas slowest walking speed? Why? Q3. What is happening between points 2 and 3, and how do you know?
Questions Q1. What does point 1 on the graph represent? The beginning of Anas walk to school; Zero distance (0 m) at zero time (0 sec)
Q2. Which part of the plotted line on the graph represents Anas slowest walking speed? Why? The part between points 3 and 4, because it has the lowest angle (shows 5 mins to travel 60 m) [The part between 2 and 3 because Ana is stationary (not waking at all)].
Q3. What is happening between points 2 and 3, and how do you know? Ana is stationary, because the line remains at 140 m; (or because the text tells us that Ana waits for her friend to get ready.)

Q1. Which section of the plotted line represents Anas walk home from school? Q2. Ana walks the fastest when she walks from school to her house. What on the graph indicates that? Q3. What is Anas total displacement after all her walking to and from school? How do you know? Questions:
Q1. Which section of the plotted line represents Anas walk home from school? The section between 4 and 5.
Q2. Ana walks the fastest when she walks from school to her house. What on the graph indicates that? The steepest slope of the plotted line which is between points 4 and 5. That Ana walks 200 m in 5 minutes.
Q3. What is Anas total displacement after all her walking to and from school? How do you know? Anas displacement is zero (0 m). We know because the plotted line returns to the bottom of the horizontal axis (the distance axis)
