In this week’s weather lab, Chief Meteorologist Melissa Frey visited Rogers Park Elementary School in Anchorage. She says it’s obvious these fourth, fifth, and sixth graders have been working hard in science.The students knew all about clouds and the tools used to forecast the weather. This year, they’ve been studying everything from the water cycle, to how Anchorage’s weather compares to the rest of the globe and how the weather impacts ecosystems and watersheds.
