Parents need to know that this outstanding site from the National Park Service promotes interacting with nature. The main objective is to complete more than four dozen activities -- puzzles, mysteries, quizzes, etc. -- to earn your "WebRanger" status. The activities vary in difficulty level and topic (parks, animals, nature, people, history, science, and puzzles). Kids can also upload their nature-related photos (they don't publish any identifiable pictures of children's faces) and stories (no personal informational allowed). There's no advertising.
Educational value:Kids learn all about the natural world -- from what can be recycled to how animals survive harsh winters.
I love this site! Its super clean, and super fun! As a plus, you get to learn about people (George Washington, Abraham Lincold, Paul Revere ect., places (streams, harbors etc) etc while also being incredibly entertaining!
