Not that many kid friendly books available to help inspire young kids about inventors and scientists. This was a book from a limited selection and what a find!! Just finished reading through it. Love that it was inclusive of women scientists. Love the lessons on words youngins may not necessarily understand. Love how it encourages kids to think of ideas of their own. And what a nice surprise to see a relevant experiment in the back of the book. I hope this book continues to stay in print. I'm glad I stumbled upon this book.
