Hi all! I just came across this great blog. It's geared more towards pre-school and Kindergarten. But It has so many fresh ideas. Definitely check out her busy books tutorial! Also, under "science with Daddy" she used test tubes. And it got me thinking: I finally know what to do with those floral tubes that I saved from my last bouquet from my husband. They would be perfect for test tubes! I'm sure I could make some sort of holder for them to stand up in.
