Life from bad smells. In G. Panieri, M. Poto and G. Bertolotto Bianc (Eds.), The Ocean Senses Activity Book (Chinese version)

Focus: To understand that hydrogen sulphide indicates that there is life at the bottom of the deep-sea. Learning objectives: With this activity, we create a nasty smell similar to hydrogen sulphide from rotting organic matter. We use that smell as a foundation for a discussion/lesson on interesting life, animals and food webs from the deep sea floor. Key words: Deep-sea, hydrogen sulphide, chemosynthesis, nematodes, tube worms, food webs.
