I recommend this page because it has lots of facts about Alaskan mammals. It is very useful for anybody in elementary school, especially when writing reports about Alaska or the animals that live there. It is easy to access and to go from this site to others. This site has a lot of information on sharks. You can find out about at least fifty different kind of sharks.
Pages are all easy for kids to read and use, and they have cool pictures.
There are lessons plans for teachers. One section is entitled The Ocean of Know Homepage, where you can find even more information on sharks. I recommend this site for students in grades 2 and above. This page is good resource for reports. They have several links that lead you to alphabetical lists of zoos in this country and in other cities in the world.
