Can you give me an axample of a compoud sentence using the word playground?

"The children were running and playing on the playground, while the adults sat on benches and watched them."

This compound sentence consists of two independent clauses, each containing a subject and a verb:

Clause 1: "The children were running and playing on the playground"

Clause 2: "the adults sat on benches and watched them"

These two clauses are joined by the coordinating conjunction "while," which indicates a time relationship between the two events.
