The Magic School Bus books have done absolutely wonderful things for children and their interest in science. Take a group of children, who become familiar/family, and a teacher that is unlike most teachers, and we bring the reader straight into a science project.
In this book, we go under water and learn about Coral Reefs. The book's author does a good job of combining a small plot, unique character traits, and just enough lesson that we enjoy learning something new, but not so much that we feel we're being lectured.
My children like for me to read the narrative portions, while they read the dialog and any sound effects that might be there.
I'm sur we all learned something new about coral reefs as well!
