Activity 9

Step 1- Start the Activity 

    -Step 1: In snap circuit experiment #242, you will create a working AM radio. (If you carefully follow directions!)

• • After you have created the experiment, you will need to go out in the hall to get an AM radio station signal.

    • These large types of radio waves don't pass through walls well!

    • Ask your teacher before going into the hall.

  • Experiment #306 is a variation of the AM radio that you may try if the first one did not work well.

    • The controls for the radio are fragile, and very touchy. 

    • Be patient and careful.

    -Step 2: For snap circuit experiment #316, you will create a working FM radio. It should scan through the band to find strong FM stations. (Just like a car radio)

• • • Show your teacher when you have this FM radio station working.

• • Experiment #307 is a variation of the FM radio. 

  • Note the differences between Experiments #316 and #307.

    -Step 3: #308 is A DIGITAL VOICE RECORDER that you can build.

• • What will you record?

    -Extra Credit:

• • Is there really a radio broadcast shooting through the room right now? Is it going through you right now?!
