What happens when you blow a whistle

Zalman brought a whistle to school today. His friends were
 very curious about it and Zalman gave them all a turn.
When the Yeladim blew the whistle it made a sound. 

The Yeladim loved blowing the whistle so much that it was brought out to the playground so they can blow it some more. 

At lunch time, the Yeladim discussed the whistle. They thought of other things
that make sound too.

Zalman: " A drum makes a sound. When you bang it with sticks. "

Teacher: " The drum makes sounds when you tap it and the whistle makes a sound when it's blown."

Zalman: "Yeah, a big drum, for Tattys."

Benjamin: "I want a small drum for children."
