This is a perfect book for summer. Even if you child did only one activity a day, they will be better educated , and have had a lot of fun by the time the new school year roles around. I like how the book was divided into subjects like water, ground, weather, etc. The illustrations and real pictures are plentiful, the instructions easy to understand. And at the end of each activity the cause and effect are explained in How it Works, and they also give a Real World Science example of the concept. Well done.
