  3. Food Webs & Food Chains • What does the arrow represent? • Is this a food chain or a food web? • What’s the difference between the two?

  4. Remember! 1. Do not eat any food during class. 2. Be careful when manipulating the pointed sticks. 3. Wash all tables and hands with soap and water before leaving class.

  5. Dissecting the Pellet:Materials: PELLET 2 Wooden sticks Petri Dish Paper Towel Sample skeletons handout You may work with a partner of your choice. Follow the Procedure on page E-38.

  10. Teacher Lens Debrief • Ordering Pellets • AQ 3 is really tricky! • Can also learn more about owl pellets and virtual dissection on the Issues and Life Science page of SEPUP website. http://www.kidwings.com/owlpellets/flash/v4/index.htm • Vomit Collector Video http://www.discovery.com/tv-shows/dirty-jobs/videos/owl-vomit-collector.htm • Would have students reconstruct skeletons and glue on cardstock – student sheet 78.1 is helpful resource. (Extra Credit Option) • Students could begin constructing food webs after this activity for research project.
