Teachers and students use professionally prepared guides to study food chains from regurgitated owl pellets. Kit allows students to investigate the diets of owls as birds of prey. Pellets are easily dissected to expose skulls and other skeletal parts. Undigested remains of animals provide bones, teeth, hair, or feathers as evidence of the prey animals. Charts of skulls and skeletons are available to assist students to identify the prey animals. Additional exercises can be conducted such as reconstructing animal skeletons or construction of food chains from the skeletons found in the pellets. Safe for student use, this kit contains 15 dried and fumigated owl pellets wrapped in aluminum, 15 student worksheets, and a Teacher's guide. Grades 3-7.
