What is the Leaf Pack Network®? A Hands-On Stream Ecology Investigation Based on Real Science! Science involves more than simply collecting data. Science is also the process of communicating and sharing results, initiated through inquiry. The Leaf Pack Network® is an international network of teachers, students, and community science monitors investigating their local stream ecosystem. Through the Leaf Pack Network®, monitors use tree leaves and aquatic insects to determine the health of their stream and to understand its ecology. Individuals participating in the Leaf Pack Network® engage in the full process of conducting research and communicating their results. Leaf Pack can also easily be implemented into any curriculum and fulfills many state and national science standards. Watch your students become empowered and energized learning about their local watershed!
