    Problem Situation

    How do we communicate? Why is it important to communicate? "The most important things for students to know when looking for a job are How to Communicate and How to Solve Problems.  You may be the only person hired in your workplace who does that activity. How will you communicate your ideas to others? Employers can and will train you. But you need to know how to solve problems. In this unit you will learn to communicate by creating a radio broadcast. It may be an interview, it may be music (approved, of course). You will learn how to communicate !!!

    Your Challenge

    Communicate with other students by creating an actual "Podcast".

    Create a 'Podcast' using a recording device that presents information in a manner that WILL be used as a classroom newscast.

    To solve the problem, your design must meet the following specifications and constraints:

    • Create a presentation that communicates an idea using audio
    • Audio presentation must be 2 to 3 minutes long and saved in digital format
    • Audio presentation must contain accurate information and at least three different sources for information.
    • Transcript MUST BE typed using Microsoft Word.
    • Be reliable...come from many DIFFERENT sources. Include bibliography in your notes!
    • Be clean...no words should be used that cannot be published in a newspaper, said on a radio broadcast, or used during a presentation IN SCHOOL. Anything that would get you disciplined in school or in public IS NOT ALLOWED. Do not create a commentary against public officials.

    Reasons why we need to learn how to communicate...as presented by LaMar Hill to the Ballston Spa faculty on September 1, 2006.

    • ...the High Technology Industry will need employees who can can work and communicate with others, individually and in teams, across functional, cultural, and geographical boundaries.
    • ...require strong communication skills

     

    In the 21st Century, the High Technology Industry will need employees who...

    • Are technically proficient in key disciplines.
    • Are well-grounded in math, science, business principles, and in computer skills.
    • Can work and communicate with others, individually and in teams, across functional, cultural, and geographical boundaries.
    • In a global economy, the locality which can provide workers with these skills will prosper.

     

    Required Skills

    • Foundation in Science and Math
    • Interpersonal Skills
    • Flexibility
    • Team Player Skills
    • Computer Literacy
    • Strong Communication Skills
    • Ability to Deal With Change
    • Appreciation of Diversity

     

     

    What is a Podcast?

    A podcast is a multimedia file distributed over the Internet using syndication feeds, for playback on mobile devices and personal computers. The term, as originally coined by Ben Hammersley in an article in the Guardian February 12, 2004 [1], was meant as a portmanteau of "broadcasting" and "iPod".[2] Like 'radio', it can mean both the content and the method of delivery; the latter may also be termed podcasting. The host or author of a podcast is often called a podcaster.

    Though podcasters' web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital audio formats by its ability to be downloaded automatically using software capable of reading feed formats such as RSS or Atom.

    The editors of the New Oxford American Dictionary declared "podcasting" the 2005 word of the year, defining the term as "a digital recording of a radio broadcast or similar program, made available on the Internet for downloading to a personal audio player".[1]

    The name has received controversy for implying one needs an iPod to listen to podcasts, when in fact all MP3 players will play them.

    Podcasting's initial appeal was to allow individuals to distribute their own "radio shows," but the system quickly became used in a wide variety of other ways, including distribution of school lessons, official and unofficial audio tours of museums, conference meeting alerts and updates, and by police departments to distribute public safety messages.

    WHAT IS A PODCAST?  HOW DO I LISTEN?
    1. Creation and distribution of amateur radio
    2. Selectively subscribing to content (audio of video)
    3. Creating audio or video content via MP3, computer, or CD ROM
    1. Web Casting (user interface) listen on your computer
    2. Podcatcher software - search tools like iTunes
    3. RSS Feeds - subscription tool that allows content to be delivered

    Sound

    Sound is the motion of molecules, which makes sound a type of kinetic energy. As sound propagates, more and more molecules are involved, which means that the energy of the sound wave is distributed over more and more molecules. Each individual molecule increases its energy by a small amount. It is much more difficult to quantify the energy contained in a sound wave; however, the energy increases the larger the amplitude of the sound wave or the higher the frequency. The energy you experience from a sound wave also depends on how close you are to the sound source.

    Bill Nye the Science Guy video with the topic on sound. 

    Notes from the video as taken by Mr. Vickery

    • Sound is just tiny movements of air- vibrations causing a wave to move.
    • An oscilloscope is a device that lets us see waves.
    • The ear is cup shaped to focus the sound.
    • Sound travels 18 times faster through metal than through air.
    • Sound travels faster through bricks than the air.
    • Submarines use SONAR to "see" in the ocean.
    • 'Slinkies' show how sound waves move through the air.
    • Air molecules squeeze together (shows air hockey pucks bumping into each other).
    • When the wave hits a barrier it bounces back...causing an echo!
    • The waves pass through each other.
    • Sound waves reflect off round surfaces, distorting the sound.
    • A speaker 'jiggles' like your eardrum! It vibrates!
    • What is a wave? Oceans, baseball stadiums. A wave is an undulation.
    • Frequency is how often the wave passes over a certain point.
    • A faster wave results in a higher frequency...slower waves result in lower frequencies.
    • Higher frequency = higher pitch....lower frequency = lower pitch.
    • "Ultrasound' turns sound echo's into pictures.
    • Natural frequency is the sound that piano strings will vibrate at.
    • If you can sing the natural frequency of an object it will vibrate!
    • Ears are specialized structures designed to receive sound!
    • Sound is a Vibe!

    Sung to "I Will Survive" it's "Sound Is A Vibe!"

    At first I didn't know... yet I was quite intrigued... to learn that sound and light are really forms of energy. But the funny thing about light is that it's both particle and wave... so in a cave... I yelled to see how sound behaved!

    And it came back... it echoed nice... the sound waves bounced back through the air so what I yelled once I heard twice. And so I ran out from the rocks... and I dashed to a telephone... where I picked up the receiver... and I dialed up my home!

    Hey do you know... how sound is made? It's really simple... it happens when something vibrates. Like now you see my vocal chords are moving to and fro... and thus these words I'm saying are just vibrations in my throat!

    And so I cried... "Sound is a Vibe!"... it travels through the air in waves and at our ears it then arrives... and then inside these tiny bones... things get all amplified... 'cause sound's a vibe, sound is a vibe! Hey, hey....
