Pennsylvania Trout In the Classroom (TIC) is an interdisciplinary program in which students in grades 3‑12 learn about coldwater conservation while raising brook trout from eggs to fingerlings in a classroom aquarium. During the year each teacher tailors the program to fit his or her curricular needs. Therefore, each program is unique. TIC has applications in environment and ecology, science, mathematics, social studies, language and fine arts, and physical education. All classrooms end the year by releasing their trout into a state‑approved waterway. Pennsylvania's statewide TIC program is made possible through a unique partnership between Pennsylvania Council of Trout Unlimited (PATU) and the Pennsylvania Fish and Boat Commission (PFBC). This partnership provides curriculum resources, workshops for teachers and program partners, technical support, brook trout eggs and food, and grants.
