Free Science Supplements from the NIH

Anyone with kids looking for science info? The NIH (National Institutes of Health) has curriculum supplements for elementary, middle and high school ability children. These units are free to educators, including home educators. (Homeschool is one of the choices under "institution".) There's a middle school unit on the scientific method which might also be helpful to Webelos Leaders working on the Scientist badge/belt loop/pin. Units can be ordered in hard copy or downloaded from the web in multimedia.
