Youngsters visiting Michigan State University’s 4-H Children’s Garden are discovering unseen information about plants in the palm of their hands. A new device called the Personal Science Assistant (PSA), similar to a hand-held personal digital assistant, reads the plant label (a radio frequency identification product known as an RFID tag). The application brings up information and pictures about each of the plant’s parts: root, stem, leaves, flowers, fruit and seeds. Link & project page.
