Dissecting the Food Web: An Owl Pellet Investigation

Dissecting a Food Web: An Owl Pellet Investigation


Dissecting an owl pellet is a great way to learn about the different ecological roles organisms play in their environment. Our new kit, Dissecting the Food Web: An Owl Pellet Investigation, challenges students to think critically about these ecological roles and to make evidence-based predictions of their own. Through hands-on activities, project-based inquiry, and informative science articles, students build scientific and environmental literacy while having fun! Go through each lesson and extension activities with the webinar at the bottom of this page.

With this kit students will…

  • Discover what birds of prey eat
  • Reconstruct a skeleton
  • Analyze data and solve real-life mathematical problems
  • Model the interconnectedness of species
  • Learn how energy flows through an ecosystem
  • Be challenged with reflection and extension activities in each lesson

The first lesson of Dissecting the Food Web: An Owl Pellet Investigation, The Food Web,” walks students through the basics of ecology concepts such as trophic levels, energy flows, and what happens if there is a disruption in a food web. Next, in “Digging into Owl Pellets” students dissect a real owl pellet and practice observing, sorting, and recording data using diagrams and a dichotomous key. In the last lesson, “Predicting Prey,” students apply ecological knowledge about different owl species to predict pellet contents and characteristics. This kit was designed for students in 3rd-7th grade, although it is adaptable for high school classrooms with these web extensions.

    I really wish your owl pellet investigation kits were available for individual homeschool students. Hope you’ll consider that possibility in the future. Thanks!

      Hi Denise, I recommend you purchasing the curriculum by itself (~$50) and order your own owl pellets online. That way you can still go through the entire kit, but for an individual family. We also recommend that if you’re with a homeschool group, share the costs of the full kit with the entire group. Hope this helps!

    We have two horned owls living at our church located in the middle of a farming community.
    There are probably only about 6 trees in the church yard. It is interesting and fun to look for the owls each Sunday. can’t see any signs of a nest anywhere.
