Ideas for Learners - Logo for Creative Education Website Needed

Education

The tag line I currently have on my website is "Promoting literacy, inquiry, and meaningful learning experiences." I have a background in gifted education, and my site is primarily a resource for teachers, homeschooling parents, and parents looking for enrichment ideas. However, the site is also used by some students. Most elementary and secondary teachers are female, but the site should not be overly feminine - maybe a bit of whimsy, though. The bulk of the site currently has book recommendations for grades 3 - 8, with summaries, reviews, and themed book lists (over 300 and counting so far). However, the logo should not suggest that the site is only about books. There will also be some writing activities, project-based learning ideas, problem-solving challenges, and a blog. I am not about selling activities or being cutesy. This is a site for intelligent teachers who want to offer thoughtful experiences to students at home and at school. My old site includes some of the same content: www.conversationpieceslearning.org, so if you can look past the lack of graphic design, you might get a sense of purpose. My current site is www.ideasforlearners.com, but I decided I wanted to get the design right before I built it completely. That's why I'm looking for a great logo!

I like 0033ff, ffff33, cc0066, 33cc00, 330099, but not necessarily all together, and I might be using one of those for a background or accent color when I re-build my website.
