The topic for this month's "Be a Webcaster" is UV index. Log on to mediamash.ca every Friday afternoon to watch the students tell you what the weather will be like for the weekend.

On this week's broadcast, the webcasters will play "Weather Idol;" a game that has contestants sing weather-themed songs.

In total, nine lucky Grade 5 and 6 classes in schools throughout Durham will be presenting weekly weathercasts during the school year in conjunction with Metroland Durham Region Media Group and 680 News. Each school gets to produce the webcasts for one month.

Metroland's videographer, Stefanie Swinson, and meteorologist Jill Taylor of 680 News, will visit the chosen classes. Each webcast will include the weekend weather forecast and one other news item, such as a "streeter" in which a Junior Webcaster will ask classmates about a given topic, a report on weather patterns for the coming month or a news report on an environmental initiative in the school. And one lucky student from each school may get the chance to visit 680 News, taking a tour with Ms. Taylor.

The winning classes are:

Laurelee Stock's Grade 5 class, Bolton C. Falby Public School, Ajax

Colleen (Mother Nature) Kinahan's Grade 5/6 class, St. Theresa Catholic School, Whitby

Michelle Nelson's class at Walter E. Harris Public School, Oshawa
