This is spin-off of USA.gov. It is aimed toward grades K-5 and contains government resources for kids in every category under the sun. Each category (such as Art, Music, Money, Health and many more) contains links to other sites that are useful, not all of them are government sites. For example, the music and reading categories lead to several Library of Congress pages, but the money category has links to different financial institution's kids pages, others lead to PBS or other appropriate places. Contains games and videos for each category, and more depending on the links.
I think this is a neat way to showcase some of the children's resources some of the government branches have developed. One category is Jobs. Clicking on this gives you an A to Z list of jobs, as well as quick links to government jobs and science jobs. Looking under A, I choose Archeologist. One link is a age-appropriate video and text description of the career, and yet another brings you to the National Park Service Archeology for Kids page. A look at the Teacher job link brings you to the Department of Labor summary description page for kindergarten and elementary school teachers. Some really neat stuff on here, I could see a kid using this for online research and getting lost playing in all the different categories and sites. Kids.gov also has sites for Teens and Grown-ups.
