The Flyer Flew!: The Invention of the Airplane

I read this to my kids during one evening. The book has lots of opportunities to work in concrete examples to show to the kids. Two examples: -- demonstrating wing warping (twisting the wings to change shape and improve lift) -- we used a spaghetti box and did the same experiment; -- creating a lightweight engine out of aluminum -- we compared a spoon and a soda can -- the spoon is smaller than the can, but the can is much much lighter. I really liked the emphasis on two brothers working together and being creative. There was plenty of looking at how inventors work -- trial and error, testing and charting data, serendipity, and perservering year after year. The glossary at the end is always helpful. The illustrations are full-color and very easy to understand. I'm very pleased with the book.
