I CAN swim using a streamlined body position.
I KNOW the effect of body shape on water resistance.
I FEEL more confident because I know how to swim longer distances with less fatigue
Make the best choice - the letter I (arrow shape of the body) - after trying all the variants
Shallow/deep water, swimming pool, open water.
Basic swimming skills: no additional equipment is needed for this task.
No swimming skills: the swimming boards/noodles can be carried in hands
The task is performed individually at given area, in lanes/freely
The task can be performed in small or larger groups. Depending on participants' swimming skills
Instructor outside the pool.
Safety guaranteed by lifeguard.
Minimum of 2 attempts for each child.
Approximately 5 minutes.
No apprehension in deep water, willing to put the head underwater
The child's task is to swim a given distance on the belly or back with different arm positions. In each repetition, the child arranges the position of the arms to form the shapes of subsequent letters: In first "Y", the second "E", the third "T" and at last "I" (the word “YETI”). The children's task is to choose the body position (the letter) at which the water drag was the least and therefore the energy expenditure (effort) was the least too (discussion afterward). An alternative for children who swim better may be swimming at the maximum possible velocity and measuring the time over a distance.
