Life from bad smells

Abstract

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.
