Grammar check for a 7-year-old: Correcting 'Sheep wool can turn into yarn. The yarn is used to make warm clothes'

Corrected sentences:

Sheep's wool can be turned into yarn. The yarn is used to make warm clothes.

Short explanation (for a 7-year-old):

1. We added an apostrophe + s (sheep's) to show the wool belongs to the sheep. You can also say "sheep wool," but "sheep's wool" is common and clear.
2. We made sure each sentence ends with a period "." so the sentence is finished.
3. If you want the sentences to sound more active, you can say: "People turn sheep's wool into yarn. People use the yarn to make warm clothes." This tells who does the action.
