A collection of original stories, poems, riddles, games, and hands-on activities which introduce math as it is used in astronomy and other aspects of space
I was a contributing writer to this series of math books. These were produced by Kirchoff/ Wohlberg. My mother, Mary Jane Martin, was the managing editor on the project. It was a joy to work with Time Life and the series was creatively challenging. The intent was to provide interesting math content for teaching and learning math at home. Math is really a language, and the earlier a child can learn and love this language, the better.
This book is about two people looking all over our solar system for a planet that has oxygen, carbon dioxide, land, water, and 70 degree tempuratures. They take a spaceship and land on all the planets. They find Earth, which is the mystery planet. I disliked this book because they check every planet when they had already found the right planet. I learned that if you weigh 21-30 pounds on Earth you weigh 1-2 pounds on Pluto because it does not have as much gravity as Earth.
