Teaching Reflection This lesson effectively introduced deep-sea exploration through visual aids and videos, which sparked students' interest. The lead-in activity of arranging ocean layers helped build a good foundation. However, some struggled with depth-related terms, needing more simple examples. Next time,I'll prepare more vocabulary support and encourage shy students with sentence frames to boost participation. 学科网（北京）股份有限公司 $
