Welcome to the interactive model of leaf decomposition (I*MOLD). The goal of this project is to explain leaf decomposition and how it relates to the Earth's carbon cycle and climate. This website contains a series of animated lessons about decomposition, an interactive model that lets you predict how different types of leaves will decompose in different climates, and classroom activities about decomposition for teachers.

BLOSSOMS video lessons are enriching students' learning experiences in high school classrooms from Brooklyn to Beirut to Bangalore. Our Video Library contains over 50 math and science lessons, all freely available to teachers as streaming video and Internet downloads and as DVDs and videotapes.
