This kit can be highly motivational to students for regular class or independent study. Both teacher and student guides are professionally produced and include easy-to-follow directions. Illustrations identify skulls of common prey species and charts are provided for students to record the data collected. Students learn about energy transfer through food chains while observing skeletal features which identify prey animals consumed. Additional studies can be conducted to evaluate animal populations within the owl's habitat, make calculations to estimate the biomass of the prey animals, or investigate the skeletal anatomy from the taxonomic features of the prey animals. 15 student worksheets, and Teacher's guide. Grades 7 and up.
