Last Saturday, I had the joy of attending a meeting that formally founded the German UNAWE Committee (which, as a side-note made me become a member of it).
UNAWE ("Universe Awareness for Young Children") is an internationally-recognized organization trying to educate young children on astronomy. The target age is rougly between 4 and 10 years. Besides astronomy, UNAWE is also about people (children) from different cultures talking to each others and sharing their experiences. This is a fantastic idea and I like it very much. There are already a number of UNAWE committees all around the world and I am eager to help grow that network.
If you are into astronomy, work with children, or both: consider contributing!
