I just started teaching science to pre kindergarten children. This book takes a concept, breaks it down into explainable elements and then provides complimentary activies to include books, songs, fingerplay, etc. I was talking about a lesson plan in Clay Cafe to a friend last weekend, and a teenager nearby piped up: "We just did that in 8th grade science." I viewed this as a real compiment! My pre kindergarten students love the class. Mothers apologize when their child is sick and cannot come! This book has been absolutely terrific! I need to see if the author has other books that she has written as well.
