| Summary: | Focus: Where are and what happens at cold seeps and how scientists study them. Learning objectives: After this lesson, students should be able to: Relate different datasets by observing and describing scientific maps Differentiate between carbon dioxide and methane gas Clarify misconceptions about greenhouse gas Explain what cold seeps are and why most gas/methane hydrates occur at continental margins Describe some of the methods scientists use to locate and study methane/gas hydrates Prerequisites: Prior to this lesson, students should be familiar with understanding maps, molecular structure and bonding, and the greenhouse effect and gases. Key words: Arctic Ocean, Methane, Carbon Dioxide, Gas Hydrate, Cold Seep, Greenhouse Gases. 重点： 冷泉在哪里, 在冷泉会发生什么，以及科学家如何研究它们。 学习目标：本课结束后，学生应该能够： 通过观察和描述科学地图，将不同的数据集联系起来 区分二氧化碳和甲烷气体 澄清对温室气体的错误认识 解释什么是冷泉，为什么大多数气体/甲烷水合物发生在大陆边缘 描述科学家用来定位和研究甲烷/天然气水合物的一些方法 前提 在本课之前，学生应该熟悉了解地图、分子结构和结合，以及温室效应和气体。 键词： 北冰洋, 甲烷, 二氧化碳, 气体水合物, 冷泉, 温室气体 |
