2 Simple Machines by: Christina Napolitano Yvette Sarmiento Eufemia N unez

3 What is a Simple Machine?  A simple machine has few or no moving parts.  Simple machines make work easier by changing the amount or the direction of the force used to do work.

4 There are six types of simple machines.  wheel and axle  pulley  incline plane  wedges  screw  lever

5 Wheel and Axle  a wheel that turns on a post to help move things quickly and easily  Gears are a form of wheels and axles  Examples: doorknob, steering wheel, and a screwdriver

6 Pulley  made of rope and string wound around a reel to change the direction of a force.  A pulley needs a rope, chain or belt around the groove to make it do work  Examples: crane, fishing pole, clothes line, and a flagpole

7 Inclined Plane  An inclined plane is a flat surface that is higher on one end  Inclined planes make the work of moving things easier  Examples: ramp, and stairs

8 Wedge  two inclined planes together used to raise an object or split an object.  Wedges are used to split things.  Examples: knife, and an ax

9 Screws  an inclined plane wrapped around a pole or shaft that is used to hold materials together or drill holes  The inclined plane allows the screw to move itself when rotated.  Examples: drill bit, and screws

10 Lever  made of a board or bar set on top of a fulcrum.  it is used to lift weight  Examples: seesaw, crowbar, baseball bat, and a rake

11 Two simple machines, make a compound Machine  two or more simple machines working together  Examples: bike and a car

12 Lesson: Students will have to make a kid inspiration chart then exchange with a partner for assessment.

13 Lesson: Students will have to make a bar graph of how many of each simple machine they found in their group. Pulley6 Wheel and Axel4 Inclined Plane7 Lever2 Wedge1 Screw10

16 Scavenger Hunt  A single pulley reverses what? Go to http://www.mos.org/sln/Leonardo/InventorsToolbox.html to look for your answer http://www.mos.org/sln/Leonardo/InventorsToolbox.html  When you put two or more simple machines together, what do you get? Click on the link below, then click on interesting facts to get your answer. http://teacher.scholastic.com/dirtrep/simple/invest.htm http://teacher.scholastic.com/dirtrep/simple/invest.htm  If the plane is flat on the floor, will it work? Why or why not? Click on the link below to find your answer. http://www.fi.edu/qa97/spotlight3/spotlight3.html  How many types of levers are there and how do they work?
