one • Objective: To identify and describe simple machines in order to analyze how simple machines are used in a roller coaster. • Core Question: What is a machine? • Drill: 1. Draw a picture of a futuristic machine that you wish you had. Explain what it would do for you. • 2.Get a new paper from the SET. Simple MachinesDay 1 SK-13
one • Brainstorm a list of machines you have used in school. • State one reason why people use machines. Simple Machines SK-13
one • READING ROADMAP • The “location” column provides the page numbers where you should focus your reading. • The “speed” column directs you as to how much time you should spend reading the information on those pages. • The “mission” column directs you as to what you should be thinking about as you read the information on those pages. • You should only answer a question in the “Mission” column if you are directed to write in the “Speed” column.

one • Objective: To identify and describe simple machines in order to analyze how simple machines are used in a roller coaster. • Core Question: What is a machine?Drill:1. Take out yesterday’s lab. • 2. You have 10 minutes to complete the reading roadmap. If you finish, review the reading to sharpen your understanding of the concepts. • 3. Write down any questions you still have about any concepts that are confusing. Simple MachinesDay 2 SK-13
one What is a machine? A device that makes work easier or more effective List three ways machines might make work easier. *multiply the force *multiply the distance *change the direction Simple Machines SK-13
one Define input force. The force you exert on a machine Define output force. The force exerted by the machine Simple Machines SK-13
one Identify the six simple machines. Inclined Plane Wedge Wheel and Axle Screw Pulley Lever Simple Machines SK-13
one Describe and draw an inclined plane. A flat sloped surface Simple Machines SK-13
one Explain how an inclined plane helps you complete work. Your input force is decreased over a longer distance. Simple Machines SK-13
one Describe and draw a wedge. A device that is thick at one end and tapers to a thin edge at the other end. (2 inclined planes put together) Simple Machines SK-13
one Describe a screw. An inclined plane wrapped around a cylinder Simple Machines SK-13
one Describe and draw a lever. A rigid bar on a fixed point called a fulcrum Simple Machines SK-13
one • Describe two ways a lever helps you accomplish work. • 1. Levers change the direction of the • force. • 2. Levers increase the effect of your • input force. Simple Machines SK-13
one Describe and draw a wheel and axle. Two cylindrical objects fastened together so that they rotate around a common axis Simple Machines SK-13
one Describe a pulley. A grooved wheel with a rope or cable wrapped around it. List examples of a pulley being used in everyday situations. window blind controls crane sail controls garage door aparatus elevator s climbing gear Simple Machines SK-13
