        The head alien, Allawallah thinks that they need the simple machines on their planet more than we need them here on Earth! After talking with Allawallah she has agreed to give us back ONE simple machine! All of our simple machines are  important and I can not decide which one to save. I need your help in deciding which simple machine to save! 

      Your job with your partner will be to investigate the functions of all 6 simple machines. After careful investigation you and your partner will decide which ONE of the simple machines to save.

YOUR TASK!

Simple Machines are tools that make our lives easier. They help us do work with a lot less stress!

As you all know aliens have stolen all of our simple machines.

The task for you and your partner is investigate and gather as much information as you can about simple machines. You will then need to record why each machine is important for mankind. Print out the Recorder Sheet 1.docx  and the Recorder Sheet 2.docx. Record your gathered data on the tables. 

Assign the role of investigator and recorder.The investigator will use the computer and the recorder will record the information found. 

 The final task will be for you and your partner to decide on one simple machine to "save" from the aliens. You both will present to Allawallah ( teacher) why you feel this is the best machine to "save". 

You may choose any way to present your decision: a dance, power point, poster, skit, a rap etc. BE CREATIVE!!!! Think outside of the box :-)

Now that you and your partner have explored the 6 simple machines it is now time to  plan and propose to Allawallah which simple machine you and your partner are going to save. You must use a  mix of creativity and correct information. You may do so using a rap, a skit, a poster etc. Your presentation must include: 

1. The name of the simple machine you and your partner chose.

Dear Scientists,

        Thank you so much for your help! Phew! Your presentations and your information has saved our simple machines! Allawallah has told me that she now understands how important simple machines are to us! She has decided to send back all of our machines to Earth! Great Work scientists! I am so proud. 

       I hope you had a BLAST exploring simple machines! I hope you now see how important they are to our lives! The next time you are cutting up meat at the dinner table you can think, "I am using a wedge to make this easier for me" or the next time you are on the see-saw at the playground you can say, "I am having fun because of a lever."  

Thanks again for your help!

P.S. Now that you know all about the 6 simple machines you may be wondering: "what if we combined two or more simple machines together ?" 

Well.. when we combine two or more simple machines we get a compound machine.

Here are some links for further exploration of compound machines. Remember compound machines are what you get when you combine two or more simple machines together.

Major Understandings: Quoted from New York State Performance Indicators (PS: 5.1b-d, f) ■ Mechanical energy may cause change in motion through the application of force and through the use of simple machines such as pulleys, levers, and inclined planes. (5.1f ) ■ The amount of change in the motion of an object is affected by friction. (5.1d) ■ The position or direction of motion of an object can be changed by pushing or pulling. (5.1b) ■ The force of gravity pulls objects toward the center of Earth. (5.1c)
