Each learner will need to purchase their own owl pellet dissection kit. The specific kit needed can be found at this website:
https://www.homesciencetools.com/product/owl-pellet-dissection-kit/

The owl pellet is NOT owl poop!! The owl pellet is regurgitated (vomited) after the owl has digested all of the animal parts that it can. The owl pellet will contain primarily small animal bones. 

The information below is from the supplier listed above:

"This hands-on owl pellet kit guides students through the dissection of an owl pellet. This complete kit comes with a large owl pellet (1-1/2" or larger), dissection tools, instructions, an identification key, and a bone sorting chart for bone identification. It has everything you need for an owl pellet dissection! Each large owl pellet is foil wrapped and dry heat sterilized. This barn owl pellet dissection kit teaches students about food chains and food webs! Examine the inside of an owl pellet to discover the indigestible parts (or bones) of the shrews, voles, and other critters that are eaten by barn owls. The included bone chart helps students to identify jawbones, skulls, and other bits and pieces that help them to further understand and define the different animals in a barn owl's food web... Safety Information: Our owl pellets have been dry heat sterilized for a minimum of 4 hours at 250°F to kill bacteria and viruses naturally present. Even so, we highly recommend that you follow these guidelines when working with owl pellets:
Work in a place separate from eating and food preparation areas.
Use disposable latex gloves or nitrile gloves during the dissection and cleanup.
Use a disposable tray or plate to contain the owl pellet during dissection. Do not dissect directly on desks or table tops.
Use only dissection tools provided. Do not let children use pencils or other personal items for dissection. Kids like to use our economical plastic forceps to take apart the owl pellet.
Use a sanitizer with paper towels or disposable sanitizing wipes to thoroughly wash hands, work areas, and any dissection tools when finished. Household bleach in a 1:10 solution can be used as a sanitizer.
Make sure everyone thoroughly washes their hands with soap and water after the dissection and cleanup."

In addition to the Outschool classroom, this class uses:
