Analysis:
1) How do simple machines make our lives easier?
                 
2) Pick three of the objects from the lab and explain how it would be like without them?  How would you accomplish the tasks they help us with without them?

3) Go to your data table and label the fulcrum for each of your levers.
                  
4) Find three simple machines at home and add them to your Results.

5) a. Sketch a picture of each simple machine; use arrows to show the motion of each.  
    b. How does each simple machine change the direction, distance, or magnitude of a force?

Conclusion


 What was your problem?
 Restate your hypothesis.  Was it right? wrong?  why or why not?
 What did you learn in this lab?
 What did you like about this lab?
 What were some challenges you had to deal with?
 What could you do next with this problem?  What other tests could you perform?
 Write down any other additional thoughts, observations, inferences, etc.

Simple Machines Online Exploration

1. a. Predict: Based on the title, Six Simple Machines, what are some images you are going to see on the video?
b. Watch the Six Simple Machines video.  Think about and give an example of each type of simple machine.  
https://ny.pbslearningmedia.org/resource/idptv11.sci.phys.maf.d4ksim/simple-machines/#.Whwo5FWnGpp










2. Copy down the definitions and examples, then sketch a picture of each simple machine term. Use www.google.com as a research tool to assist you in finding an example of each simple machine; use the fill in the blanks to help you in organizing your information. 



a. Gears:
 
Two toothed wheels fit together either directly or through a chain or belt so one wheel will turn the other.
Examples: Clock, Automobile, Drill, __________.



b. Inclined plane:
      
A sloping surface, such as a ramp.
Examples: Staircase,  Bottom of a Bath Tub, __________.



c. Lever:
    
A straight rod or board that pivots on a point known as a fulcrum.
Examples: Seesaw, Bottle Opener, __________.






d. Pulley:
  
A wheel that usually has a groove around the outside edge. This groove is for a rope or belt to move around the pulley. Work is made easier because pulling down on the rope is made easier due to gravity.
Examples: Flag Pole, Crane, __________.


e. Screw:
 
An inclined plane wrapped around a shaft or cylinder.
Examples: Bolt, Spiral Staircase, __________.

f. Simple Machine:   
A machine with few or no moving parts. Simple machines make work easier.




g. Wedge:

Two inclined planes joined back to back. Wedges are used to split things.
Examples: Axe, Zipper, _________.

h. Wheel and Axle:
 
A wheel and axle has a larger wheel (or wheels) connected by a smaller cylinder (axle) and is fastened to the wheel so that they turn together.
Examples: Door Knob, Wagon, _________.


i. Compound Machine:
Two or more simple machines working together to make work easier.
Examples: Wheelbarrow, Can Opener, Bicycle, _________.
