<p>Host John welcomes the families to TV3 Medford and introduces station manager Dawn Natalia. John explains that the families will be creating a 30-second Public Service Announcement (PSA). They will have 15 minutes to work on their script, then three &lsquo;takes&rsquo; to record their PSAs. TV3 will broadcast the best of the 3 takes. Dawn and Production Manager Sean Carroll will judge all three PSAs and declare a winner. Who will win the challenge?</p>
<p>John helps the families rehearse their scripts then watches as they record their PSAs. John explains the final challenge. The goal of the   Community Challenge is to eliminate carbon output completely by earning 'Community Carbon Credits,' one credit for every pound of carbon they save outside of their own household. Their new 'low-carbon friends'  must be within 30 miles of the Prudential Center. Changes their friends commit to must be previously unplanned, measurable, and sustainable for one year. John wishes the families good luck and promises to see them at the final awards celebration.</p>
