"학생들이 공항의 온도를 기록해요."
Translation:The students record the airport's temperature.
記(기록할 기): keep in mind, remember, record
錄 (기록할 록): copy, write down, record
since the individual meanings are so similar, I will try to find words that include these characters:
記: 기억(memory), 기념(commemoration), 기사(account,article,report), 기입(entry), 기자(journalist)
do note that 錄's pronunciation changes when in the beginning of a word to 녹
