2 Screen #1 In this lesson you will learn about the six types of simple machines and how they make our lives easier. By the end of this module you will be able to sort and label simple machines into their correct categories. Simple Machines Lesson Objectives Students will accurately sort and label objects into the simple machine categories.. Page 2

3 Screen #1 Simple machines are devices that make work easier for us. Without any motorized parts, a simple machine will increase or change the force needed to accomplish a task. Simple Machines Tools for Making Work Simple Lever Wedge Simple machines are all around us. In fact, you have probably used a simple machine today. Do you have a bicycle? If so, the hand brake is a simple machine called a lever. Your bicycle chain uses a simple machine that is called a pulley, and the tire uses the wheel and axle simple machine. I m sure there are bolts on your bicycle... that is the simple machine called a screw. And if you rode your bike over a ramp, you used an inclined plane. Last, if you have ever experienced a flat tire, you could have run over a wedge simple machine, such as a thumbtack, nail, knife or razor. Let s move on to learn about each simple machine in more detail. Instructions for Interactivity Inclined Plane Pulley Screw Wheel & Axle The screen will open with the image of the bicycle. As each simple machine is mentioned, the item and its associated label will appear around the edge of the bicycle. Images and labels will appear in the following order: 1. Top left picture with label Lever. 2. Label Pulley and arrow pointing to the bike chain. 3. Label Wheel and Axle with arrow pointing to the wheel and axle. 4. Label Screw with arrow pointing to the screw on the handlebar. 5. Bottom left image with label Inclined Plane. 6. Top right image with label Wedge. Page 3

4 Screen #2 Simple Machine - Lever Let s start with the simple machine called a lever. A lever is a straight, solid item that is supported against another object. The object that supports the lever is called a fulcrum. Levers make our lives simpler by helping us do common tasks. Did you turn on a light switch lately? If so, you used a lever! If you ever handed in an assignment that was more than one page, you may have used a lever to keep them together a stapler. A fun recess activity for young children is playing on a lever called a seesaw or teeter-totter. And we all use a very common lever every day, the little handle that flushes the toilet. What other levers have you used recently? Functional Instructions The screen will open with the text only. As each item is mentioned, it will appear on the screen. Items will appear in the following order: - Light Switch - Stapler - Seesaw - Toilet Page 4

5 Screen #3 Wedges Now let s talk about the simple machine called a wedge. A wedge is used to cut, chip, or push items apart. A wedge will normally have at least one side that is slanted with a narrow or sharp edge that cuts, splits, or opens the object. Some examples of wedges are: Scissors Knives Door stops Chisels Functional Instructions The screen will open with the text only. As each item is mentioned, it will appear on the screen. Page 5

6 Screen #4 Let s take a moment to see if you can distinguish between a lever and a wedge. Drag each picture to the correct area. CA: Nice job! You have identified different lever and wedge simple machines. What is a lever and what is a wedge? Levers Wedges Instructions for Interactivity Display items on the screen with instructions As students drag the items, they will snap in place if they select the correct area. As students drag the items, they will snap back if they select the in correct area. Correct answers: Stapler and seesaw are levers. Axe and hedge trimmers are wedges. When all items are correct, display CA. Page 6

7 Screen #5 A pulley uses grooved wheels with a rope, cord, or chain to move objects. Pulleys simplify our lives by allowing us to move heavy objects or things that are in hard to reach places. Some examples include: Pulleys Elevators Buckets in wells Theatre style curtains Construction equipment Functional Instructions The screen will open with the text only. As each item is mentioned, it will appear on the screen. Page 7

8 Screen #6 The inclined plane is a flat surface that is arranged at a slant. It makes life simpler by allowing things to be moved with less effort. Some examples include: Inclined Plane Ramps Slides Bathtubs (the bottom of the bathtub is slanted to allow water to drain out) Functional Instructions The screen will open with the text only. As each item is mentioned, it will appear on the screen. Page 8

9 Screen #7 Let s do another check of your knowledge of simple machines. Drag the text box inclined plane to the image of an inclined plane. Drag the text box pulley to the image of the pulley simple machine. CA: Well done! You understand what simple machines are pulleys and inclined planes. Inclined Plane Pulley Instructions for Interactivity Display items on the screen with instructions As items are moved to the correct picture, they will snap in place. As items are moved to incorrect pictures, they will snap back. Correct answers are: Handicap vehicle ramp is an inclined plane. Construction pulley is a pulley. When both items are correct, display CA. Page 9

10 Screen #8 Another simple machine is the screw. Basically, it is an inclined plane wrapped around a cylinder. They simplify our life by holding things down or together. Some examples of screws are: Screw <Sketch a representation of on-screen visuals here.>> Drill bits Jar lid Light bulbs Functional Instructions The screen will open with the text only. As each item is mentioned, it will appear on the screen. Page 10

11 Screen #9 The last simple machine is made up of two parts, a wheel and an axle. The axle is a rod that is placed through the wheel. As the axle turns, it moves the wheel. It makes our lives easier as it allows us to move objects that we would not be able to move on our own. Some examples include: Wheel and Axle Tires on cars and bicycles. Roller skates Pencil sharpener Functional Instructions The screen will open with the text only. As each item is mentioned, it will appear on the screen. Page 11

12 Screen #10 We will now pause to see if you can distinguish between the six simple machines. Click on a picture and drag to the name of the simple machine. Wheel and Axle Wedge CA: Well done! You have successfully identified the six simple machines. Inclined Plane Pulley Screw Lever Instructions for Interactivity Display items on the screen with instructions. A line will be drawn from the picture to the word as the student drags and drops. If the item is correct, the line will remain in place. If the item is incorrect, the line will disappear and beep sound will play. Correct answers are: Page 12

13 Wheel and axle is the roller paint brush. Wedge is the fireman prying open a door. Inclined plane is the treadmill. Pulley is the construction equipment hoisting a big blue box. Screw is the light bulb. Lever is the nutcracker. When both items are correct, display CA. Page 13
