    Invertebrate Lab: Earthworms and Soil Fertilization
    Free Lesson Plan
     
    Lab
    How do earthworms influence soil structure? Students observe and discuss how worms ingest soil, break down organic matter, and eject material as surface or sub-surface casts. Also discussed is the formation of water-stable aggregates, the aeration of the soil, and the improvement of soil water-holding capacity.

    Food Chain Lab - Owl Pellets
    Free Student Handout
     
    Lab
    In this food chain lab, students dissect owl pellets to learn how the owl is part of a food chain. Since the owl regurgitates these compact pellets, owl pellets are undigested parts that the owl eats, which contain fur and bones of small rodents. Dry pellets will not smell and are acceptable for students to handle with gloves.
