MS-LS2.A: Interdependent Relationships in Ecosystems Lesson Plans

  • Lab Experiment
    Owl Pellets
    Student Handout
     
    Experiment
    Owl pellets can be used to teach a part of the natural food chain. They can also be used to teach skeletal structure of rodents. Owl pellets are compact undigested parts which the owl eats. The owl regurgitates these compact pellets which contain fur, bones, etc. of small rodents. Dry pellets will not smell or be unpleasant for students to handle.

  • Lab Experiment
    The Earthworm and Soil Fertilization
    Lesson Plan
     
    Experiment
    Students observe how an earthworm influences soil structure (The ingestion of soil; the partial breakdown of organic matter; the mixture of these factions, and the ejection of this material as surface or sub-surface casts; the formation of water-stable aggregates; the aeration of the soil, and the improvement of its water-holding capacity; the addition of lime to the soil.). Students should develop an appreciation for earthworms.
