People have taken dangerous risks trying to fly. Some inventors built wings for their arms and flapped them like birds. Others tried to fly with balloons or tried to glide with the wind. This book describes the creative, fascinating, and wacky experiments that people tried before the airplane was invented. This nonfiction picture book is an excellent choice to share during homeschooling, in particular for children ages 4 to 6. It's a fun way to learn to read and as a supplement for activity books for children.
This is a Stage 2 Let's-Read-and-Find-Out, which means the book explores more challenging concepts for children in the primary grades. Let's-Read-And-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
