At its heart, Optics for Kids is a massive resource, filled with information about all manner of optics topics, from research and history to unanswered questions. Once kids dig into this site, if they are interested in optics, they will be consumed and disappear for hours. We'd like to see the site's producers create an opportunity to immediately connect with kids who don't know what optics is. Yes, the optical illusions are a fun start, but more challenges and questions on the front page might help pull visitors further and more quickly into the scope and breadth of learning opportunities.

Once inside the site, the try-this-at-home experiments are well worth the effort. The resources (for parents, teachers, and kids) are thorough and well considered. The profiles of optics researchers (young and old) are inspiring. The history and tutorials add icing to the cake of this unsung resource for budding scientists and optics geeks.
