NSDL

The website I chose to search was NSDL. I searched "weather," and found a lot fo useful results. My top three were :
Weather Scope
This website had weather related projects and activities that would be fun for students to do. The project I liked is one that would allow students to access real weather data on the internet, and make charts and graphs using the info found. I would use this project to teach students how to read weather data, and make charts and graphs.
Dan's Wild, Wild Weather Page
This website had a list of all types of weather realted topics. When you click on each topic it has info about each, and activities to go with it. This website could be used in the classroom just to get info. about a weather related topic, or it could also be used to find projects and activities to do with each topic.
Climate
This website describes weather vs. climate, different climate regions in the united states, gives a teachers guide, and also gives activities that have to do with climate. This is a great website for getting info. about climate. I would use this website to teach students about the differences in weather and climate.
