While studying gas laws, high school chemistry students at Unionville High School in Kennett Square, Pennsylvania, created children’s books about the properties of gases, geared toward ages 8-12, to display their understanding of the science content. Because the high school students were eager to share their books and their science knowledge with elementary students, a partnership was formed between the high school and a local elementary school. Using their science stories as the central focus, the high school students and their teacher created a half-day science program for fourth- and fifth-grade elementary students. In addition to highlighting the high school students’ own books, the program also included a series of laboratory activities, demonstrations, discussion, and writing activities.
