Looking at a pile of compost, you’d never guess that it is alive and thriving! The Hot Pile exhibit is made up of all manner of plant waste, but ends up looking like soil through the process of decomposition. Join environmental scientist Sue Pierre as she discusses the bacteria, fungi, and microscopic insects who break down plant matter to produce compost and heat. Go further by experimenting with your own hot pile in a styrofoam box at home!
