George Washington Carver spent his life asking questions and looking for the answers. He gained a reputation as the farmers' best friend after teaching about crop rotation. He told farmers to grow peanuts and sweet potatoes to "rest" their soil between cotton crops. And what could they do with all those peanuts? Carver developed more than 300 peanut-based products-from milk to printers' ink-and more than 100 ways to use sweet potatoes. Young children love the story of this exceptional inventor. http://www.mackinvia.com/3208103 .
