Terrarium Habitats Teacher's Guide

"The guide includes concise and interesting biological information on a number of possible small organisms (sow bugs, isopods, earthworms, snails...) that can become terrarium inhabitants. Students observe these and other terrarium components and record changes over time. There are detailed instructions on setting up and maintaining the terrariums. Special features include an optional soil-profile test for older students, and making "decomposition bags" to learn more about the natural life cycle."
