# Grade 7 Science Module: Motion in Graphs and Dots

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.

When you walk to the store near your house to buy your favorite snack, there is motion. When a car passes by your house, that car is in motion. Basically, motion is the change in position over an interval of time. The motion of an object can be described in many ways through its position, how far it has traveled, or how fast it is moving. The equations you have learned in the previous lesson are great ways to mathematically describe the different concepts of motion.

Similarly, using mathematical pictures like motion graphs and tape charts are also effective tools in representing the motion of objects. By simply analyzing visual representations like diagrams, graphs, and charts you will know if an object is in motion or not, whether it is moving with constant speed, or changing in speed or not. In this module, you will learn how to create and interpret the motion of objects through tape charts and graphs.

Most Essential Learning Competency:

• Create and interpret visual representation of the motion of objects such as tape charts and motion graphs.

This module is divided into two lessons:

• Lesson 1- Motion Graphs
• Lesson 2 – Ticker Tape Diagrams

After going through this module, you are expected to:

1. describe the motion of objects in relation to the slope of the line on a distance-time graph and speed-time graph;

2. create motion graphs to represent the motion of objects;

3. describe the motion of objects by interpreting ticker tape diagrams; and

4. create ticker tape diagrams to represent the motion of objects.
