This is a site from the Abbe Museum in Bar Harbor, Maine. There is a tribal location map. There are links to Basketry Workshops and Archaeology. It is a good intro to the Penobscot, Micmac, Maliseet and Passamaquoddy tribes. I would recommend this site to anyone in 4th grade or older.
Native Web is a very good site for several reasons.
Under Site Map, you will find a large list of things to look up, such as Stonework, Nations Index, Declarations, Events, etc. Under Native Tech you will find bead work, plants and trees, recipes, and so on. Also, you can find information about indigenous people from other countries under Abya Yala Net. I recommend this site for kids ten and up. It was developed and is being maintained by a volunteer organization of ten people around the United States and Canada.
