Ultrasonic Range Finder Lesson 4 - How can we use data to describe movement?
STORYTELLING 1. How far did Christopher s car travel between points A and B? 1. How much time did it take for Christopher to travel from point A to point B? FINDER RANGE 1. Describe the motion of Christopher s car between points B and C. 1. What is the speed of the car between points A and B? 2
STORYTELLING 1. What do the labels tell us? 1. What do you think is happening in the graph? FINDER RANGE 1. How can you tell? 3
STORYTELLING 1. What do the labels tell us? 1. What do you think is happening in the graph? FINDER RANGE 1. How can you tell? 4
STORYTELLING 1. What do the labels tell us? 1. What do you think is happening in the graph? FINDER RANGE 1. How can you tell? 5
STORYTELLING 1. Open New Piper Project 1. View data. FINDER RANGE 1. Follow the directions in your Graphic Organizer. 6
EXTENSION DISTANCE DISTANCE FINDER RANGE TIME TIME How can we calculate speed? 7
EXTENSION How can we calculate speed? y y y FINDER RANGE x x x A steep line indicates a fast speed A shallow graph indicates a slow speed A flat line indicates zero speed, the object is stationary 8
Where does the line have a steep slope? SLOPE What happened here? Distance travelled = 4 miles Time travelled = 1 hour FINDER RANGE Where does the line have a shallow slope? Distance travelled = 1 mile SLOPE = distance covered time Time travelled = 1 hour 9
REFLECT! Respond to these writing prompts: 1. How do waves help you experience the world around you? FINDER RANGE 1. How do graphs help us describe situations in our lives? 10
