In Charlene Tuttle's sixth-grade classroom at Jamestown's Lawn School, baby chicks chirp in a straw-filled box. Remotely-operated vehicles designed by her students are ready to explore the ocean depths, and green tendrils from a hydroponic garden climb trellises to the ceiling. Her passion for science and innovation as an educator led her to be named the state's top teacher in a boisterous celebration on Wednesday.
