UNAWE or Universe Awareness is a program started in Europe that seeks

to educate children aged 4-10 years (especially those from underprivileged communities) about astronomy because it embodies a unique combination of scientific and cultural aspects:

• Our awe-inspiring Universe captures the imagination of children, making it a great stepping-stone to introduce youngsters to science and technology. Indeed, many scientists can trace their interest in science to a moment as a young child when they were first introduced to the wonders of the cosmos.
• Considering the vastness and beauty of the Universe and our place within it provides a special perspective that can help broaden the mind and stimulate a sense of global citizenship and tolerance.

The organization now has projects in 47 countries. Their website has a lot of information and resources about the program, how to get involved, and about amateur astronomy.
