I just ran across a cool website called "Wonderopolis". You'll find their widget on the right. Check it out!
Here is what they have to say about themselves:
Explore. Imagine. Laugh. Share. Create. Learn. Smile. Grow.
Welcome to Wonderopolis®, a place where natural curiosity and imagination lead to exploration and discovery in learners of all ages. Brought to life by the National Center for Families Learning (NCFL), our Wonders of the Day® will help you find learning moments in everyday life—ones that fit in with dinner preparations, carpool responsibilities, a stolen moment between breakfast and the bus, or within school curriculum and education programs.
Wonder is for everyone. It can happen anywhere and at anytime. Connecting the learning we do in our schools, our homes, and our communities, Wonderopolis walks the line between formal and informal education. Each day, we pose an intriguing question and explore it in a variety of ways. Our approach both informs and encourages new questions, sparking new paths of wonder and discovery in family and classroom settings.
