Word: Ozone
Part of Speech: Noun
Meaning: Ozone means a gas high up in the air around the Earth that blocks many of the strong rays of the sun.
Syllables: o - zone
Tricky part: You do not hear the e at the end, so children often stop at ozon. That quiet letter makes the o before it say its own name.
Watch out for: ozon, ozoan
Memory tip: Think of the last e as a guard at the end of the word: it says nothing, but the word is not finished without it.
Example 1: We made a poster about the ozone layer.
Example 2: Our teacher drew the ozone layer on the board.
Example 3: Mira read a short book about ozone and the air.
Ozone has a sharp, clean smell that some people notice after a thunderstorm. Its name comes from a Greek word meaning to smell.
