Webquest Educational Software

As I was exploring educational software, I cam across whyville. http://www.whyville.net/smmk/nice I really enjoyed this website. It was a little hard to understand at first, but once I played around with it it became really easy to navigate. I think kids would have a really good time on this website, and I don't think it'd be too difficult for them to use. I can't decide which grade level I want to teach. Originally, I was thinking I would do Kindergarten because I've had some experience with children that age. But, I'm not sure if talking about nutrition would be too difficult for a child that age. I played a game on Whyville about fixing someone's diet. Some of the problems included too many calories, not enough calories, too much fat, not enough vitamin A, etc. I really, really enjoyed this activity. I feel like it could teach kids a lot about what nutrients different foods have in them. A few standards I could meet would be to help kids become more familiar with technology and the resources that they can use. I want to show them that technology can help them with all areas of their lives, even with something as simple as what they eat.
