MB was doing her science work on the computer today - browsing through wetland links from her Earth E-book by DK. She came across this video from Idaho Public TV. After she finished watching it I did some looking at the website and they have various science videos - done for elementary-age kids dating back to 1999 available. They are around 20 minutes. The site is Dialogue 4 Kids.
The video on wetlands had to professional ecologists who answered questions from kids across Idaho and various photos. Some of the info was focused on Idaho, but alot of it was general information.
