Unit # of Texas Essential Knowledge and Skills/Student Expectations (TEKS/SEs) Days/Lessons The student will: Unit 10: Simple 5 class periods (90 Unit 10: Simple Machines (5 OR 9 lessons) Machines minutes each) 6.8E investigate how inclined planes and pulleys can be used to change or the amount of force to move an object. Students 9 class periods investigate how (45 minutes each) simple machines such as inclined Suggested Pacing: planes and pulleys are used in ________-________ everyday situations Notes to Teacher Some students may not be familiar with spring scales and how to measure force using them. Provide opportunities for hands-on investigations in which students measure force using pulleys and inclined planes. Students investigate different types of pulleys and inclined planes with various slopes. Academic simple machine inclined plane pully load Vocabulary force movable pulley fixed pulley pulley sytem spring scale newton Vertical 5th Grade Before 7th Grade Alignment After 7.7C demonstrate and illustrate forces that affect motion in everyday life such as emergence of seedlings, turgor pressure, and geotropism Science Background Information The interactions an object has with another object can be explained and predicted by using the concept of force. A force is a push or pull that causes a change in motion for one or both of the interacting objects. Motion is the movement of an object after force is applied, or a change in position over time. Force can move, stop, or change the direction of a moving object. Simple machines have few or no moving parts. They are tools that make “work” easier. Work occurs when force is used to cause motion. Work can be thought of as (1) an amount of force needed and (2) the distance over which the force is used. Simple machines do work because they apply force over a distance. Simple machines are tools without an internal source of energy and are limited by the Law of Conservation of Energy; they cannot produce more output
