Wildlife Conservation Center Aquarium 7th Grade:
NY
Aquarium: To learn the types of skeletal systems
Skill:
Compare and contrast
Objectives:
Students will read, write, and speak for critical analysis and evaluation.
Review:
Prior to beginning this lesson there was an introduction to the human
skeletal system and its relation to he support and movement of the human body.
Motivation:
How do you define a skeletal system? Write a brief description of a skeletal
system function in a living organism. Be specific as to how you would describe
a skeletal system.
Activity:
Completion of the characteristic chart.
The
students have engaged in a weeklong assignment gathering pictures and information
about a given list of organisms. The chart will allow for the arrangement
of the organisms according to skeletal system traits.
Directions:
Using the information compiled from the list organisms given in class, complete
the following handout as a group. Upon completion the results will be placed
on the chalkboard for a class analysis.
Questions:
What did you notice about the organisms chosen to
have internal skeletal systems? What are some of their common characteristics?
What about the organism with external characteristics?
How were the two groups different? What were some
of the features that made them different?
Answers
will vary from the presence of a shell, hard outer coating, or lack of bones.
Student responses will be recorded on the chalkboard. With the two groups
of skeletal systems clearly defined continue to part B.
Part
B:
Have
students attempt to complete a second handout involving developing a description
for each type of skeletal system. (Internal and External)
Conclusion:
Introduce the appropriate terminology for skeletal systems possessing the
qualities discussed in class. Supply the students with a working definition
for each type of skeletal system.
Visit:
New York Aquarium
Students
will take part in the educational program designed and run by the aquarium.
Develop a chart similar to the one in class, and classify the skeletal systems
of the organisms observed during the trip.
Homework:
Choose 3 organisms discussed on the trip and justify your classification of
its skeletal system. Think about how the skeletal system of the organism given
in class benefits them in their natural environment. Be specific. Write down
your thoughts in a paragraph 8-10 sentences in length.
