### Simple machines scavenger hunt

1. 1. Simple Machines Scavenger Hunt<br />By: Sasha Volkodav<br />
2. 2. Simple Machines are used for the mechanical <br />advantage. It makes something easier to do,<br />but it takes longer to do it.<br />Simple Machines<br />http://www.google.com/imgres?imgurl=http://www.woodland.k12.mo.us/faculty/tburke/science/Simple%2520Machines/simplemachines.gif&imgrefurl=http://www.woodland.k12.mo.us/faculty/tburke/science/Simple%2520Machines/six%2520simple%2520machines.htm&usg=__turef6kq8IR80g7jjTDn-KvlnJk=&h=300&w=502&sz=37&hl=en&start=1&um=1&itbs=1&tbnid=wVI8dOA-bZxxhM:&tbnh=78&tbnw=130&prev=/images%3Fq%3D6%2Bsimple%2Bmachines%26um%3D1%26hl%3Den%26sa%3DN%26tbs%3Disch:1<br />
3. 3. A wedge pushes materials apart, and cuts things. The knife cuts through bread <br />or food, and thefork cuts through food when you use it to eat salad, fruit, etc.<br />(The knife was found in my kitchen.)(The fork was found in my kitchen, as well.)<br />Wedge<br />
4. 4. A wheel and axle makes it easy to move things by rolling them. It also reduces<br />friction. The car makes it easy to go from place to place, and the roller blades also<br />make it easy to move somewhere at a quicker rate.<br />(The car was found in the parking lot.)(The roller blades were found in the storage room.)<br />Wheel & Axle<br />
5. 5. A lever makes lifting weight easier. It uses a fulcrum to redirect force over a longer distance.<br />Without a bottle opener it would be very difficult to open a bottle and it would take a lot longer. <br />Also without a screwdriver it would be hard to put things together with screws, or take them <br />apart.<br />( The bottle opener was found in my kitchen. ) ( The screwdriver was also found in my kitchen. )<br />Lever<br />
6. 6. An inclined plane makes it easier to move objects upward, but you have to go <br />further horizontally. Stairs make it easier to get from one floor to another,<br />instead of jumping to where you need to go.<br />( Stairs in front of my home. ) ( Stairs in a basement. )<br />Inclined Plane<br />
7. 7. A screw turns the rotation into a lengthwise movement, it takes up many twists to go a short <br />distance, and it holds things together. Without screws nothing would be able to hold together, <br />and everything would be one piece. It would be very hard to get a computer desk, cabinet, etc. <br />through the door without screws to put the things together.<br />( I found the jar lid in my kitchen cabinet. ) ( I found the screws in the tool shed. )<br />Screw<br />
8. 8. A pulley makes lifting things with a rope easier. It redirects force and the addition of <br />additional pulleys. To put a flag up on the top of a flag pole would be tricky if we didn’t have a <br />pulley. If we didn’t have window shades/blinds, too much sunlight would get into our homes, and <br />it wouldn’t keep our homes cool. We also wouldn’t have our privacy.<br />( The window shades were found in my bedroom. )( The flag pole was found outside of a school. )<br />Pulley<br />
9. 9. Complex Machines are made up or two or more <br />simple machines.<br />Compound Machines<br />http://peruperusals.files.wordpress.com/2009/07/beldray-trojan-wheelbarrow1.jpg<br />http://static.howstuffworks.com/gif/power-drill-1.jpg<br />
10. 10. The simple machines that make it up:<br />Lever-The lever is the top arm of a stapler. As you push down on the lever, it<br />transfers energy into a staple. This helps staple your papers.<br />Wedge-The staple in a stapler is a wedge. As you push down on the stapler it<br />sends out a sharp metal staple. This staple pierces through the paper, which<br />makes it a wedge.<br />Stapler<br />
11. 11. The simple machines that make it up:<br />Wedge- The wedge is the simple machine that slices open a can. When the can<br />opener turns the can, this wedge cuts through the metal top.<br />Lever- The two levers are the arms on the can opener. These levers open and <br />close on one fulcrum. This helps grip and open the can.<br />Gear- The gear is a simple machine that grips and helps rotate the can. The <br />gear uses energy from the turning handle to spin the can around.<br />Wheel and Axle- The wheel and axle is the rotating handle on the can opener. <br />Energy transfers to a gear and wedge, when you turn the handle. This is what<br />rotates and opens the can.<br />Can Opener<br />
