I was surprised by how much I liked this book (but then, all Evan Moor products are so good.) I printed off the units and made little books that we used whenever I needed a 15 minute time filler. The best feature is the emphasis on the vocabulary words. I believe if the kids know the vocabulary, they will do much better on our standardized test. My only "con" is that this book just doesn't cover enough topics - no simple machines, no planets, no rock cycle. I like the depth, but not the breadth. I plan to get Daily Science Grade 4 for some of these topics.
