NC Aquarium at Fort Fisher : Sea Turtles

Turtles Under Human Care

Whole Class Introduction to the Lesson

You will need at least one computer with Internet connectivity and a projection device, a classroom with more than one computer, or access to a computer lab.  This introduction will take approximately 10 minutes to complete.

Project the following video clips for the whole class. View them in order as listed.

 

Sample Questions:

  • Describe the characteristics of the workers who help the sea turtles.
  • What might happen to the sea turtle populations if there were not rescue and conservancy organizations?
  • List some of the ways that you observed sea turtles being harmed.

As part of the introduction, you may want to review some of the glossary terms in advance of students going online. At this point you can launch the WebLesson as whole-class activity using a projection device, or you can assign students to work individually or in teams in a computer lab.

 

Rubric

Excellent (30 - 20)

An excellent student response meets all the project requirements and demonstrates that the student absorbed key lesson concepts and gave them thoughtful consideration. The response shows original thinking, creativity, and a strong sense of purpose. Ideas are organized and clearly articulated according to the proper conventions of writing (at this grade level).

Satisfactory (20 - 10)

A satisfactory student response meets most of the project requirements but overlooks one or more important elements. It reflects a general understanding of the key lesson concepts but shows little depth. The response shows little creativity or originality. Ideas are somewhat disorganized and difficult to follow, and there are numerous grammatical and mechanical errors.

Needs Improvement (10 - 0)

The student response is perfunctory, showing little or no effort. It is unclear if the student thought about or even read any of the lesson content. Ideas are scattered or off-topic. If possible, ask the student to revisit the lesson with a peer or mentor and then rewrite his or her response.

Introduction
Many people all around the world recognize the importance of preserving the natural aquatic environments in order to provide a safe haven for the sea turtles. Saving turtles means we have to defend their homes, preserve their ability to move about freely, and ensure their path to successful nesting.

Sadly, too many sea turtles are caught in nets or harmed by boats or other human activities. They fall ill when temperatures drop and they have fewer and fewer places to go when humans encroach upon their natural environments.
Scenario
Your class has been invited to visit the local sea turtle hospital and volunteer on a weekly basis. In order to help the injured sea turtles, your class will first learn more detailed facts about these aquatic reptiles.

Conclusion & Project
Conclusion
The sea turtle hospitals help to save and restore the health to all species of sea turtles that have fallen ill or have been injured. This is a time-consuming and even expensive project and it is very important that the hospitals are supported by the community.

The people who work at the hospitals work hard to rescue and help the sea turtles get back to their healthy state. They are then released back into the wild. The released sea turtles are tracked so that scientists can observe and study the animals in order to learn more about how to help them.
Project
Create a list of questions that you would ask the rescue and medical workers at the turtle hospital. What area of the turtle hospital would you be most interested in working? Why?
