What Happened to My Nighttime Melodies?
Word Format for Printing

What a week it's been. First there was panic as the stories poured in about the coming hurricane. Dad kept saying, “I think that we should stay. We’ve had so many false alarms and our house is constructed of cement block, anyway.” Mom disagreed vehemently. “Safety first, we need to think of the kids,” she said. We proceeded to frantically board windows, pack things and put them away in preparation for the storm. Although I've lived in southern Florida all my life, it never gets any easier when hurricane season comes. We were off to my Grandparents home in northern Florida to wait out the storm.

The hurricane swept through our town but we were lucky this time. There was very little damage to our home, considering how high the winds were that blew through the area. However, something is now different. I can't really put my finger on it yet. Is it just the calm after the storm? It's almost an eerie silence. What's missing?

I know what it is! It's the sounds of the owls from the nearby sugar cane fields. Did the storm blow the owls away? Why aren't they lulling me to sleep with their calming, serene, whooo…whooo…

PROBLEM:
This may not only be a problem for owls but also for humans. Complete your owl pellet dissection and make a hypothesis as to why humans can be affected by the loss of the owl population resulting from hurricanes.

Facts and Questions
The class will complete individual facts and questions sheets then form cooperative learning groups. (directions)

PBL Group Jobs
Each student will receive a "job" in the group and students will get 10 minutes to brainstorm using poster paper or white boards.

Lab Activity

Owl Pellet Dissection

Each lab group will collect data about their owl pellet and record it in a data table. They will then construct a food web from pictures which are provided. Following the dissection and food web activity, students will determine how the loss of owls as a result of hurricanes affect humans and other organisms.
