Before going to the swimming pool discuss with the class the
principles of fluid dynamics and how they effect a swimmer.
|
|
Discuss safety rules that need to be followed at the swimming pool.
You will also need permission slips from parents with information about
the student's ability to swim. If a student doesn't feel comfortable
about swimming they can observe those who do swim.
|
|
After arriving at the pool sight go over the rules briefly again.
|
|
Split the class into four groups. Have two boys groups and two girls
groups.
|
|
Ask one of the girls groups to enter the water and try the
Paddlewheel Arm Pull and the Caterpillar Arm Pull. (These two arm pulls
are visualized in the Teacher Text under Fluid Dynamics of Swimming in
the K8AIT program). Take about 15 minutes with each group to experience
the two types of arm pulls. Also, ask the students to position their
bodies in different ways as they use the two arm pulls and their leg kick
formation as well. Repeat the process with each of the groups.
|
|
|
|
Do timed trials to compare the effectiveness of the two types of arm
pulls combined with the various body and leg kick formations.
|
|
Afterwards sit on the side of the pool area and review with the
students what they have experienced in the water. Encourage the students
to use the terms under 'Words to Know' as they describe their experience.
|
|
As a supplemental assignment ask the students to write a one page
essay on what they have learned about the principles of fluid dynamics
the next day in class. Have the students read their essays to one
another.
|
|
As a bonus you could invite a guest speaker to your room who is an
Olympic caliber swimmer to discuss their knowledge about fluid dynamics
in relationship to their swimming style.
