Explorers set up Windogradsky columns with local mud so that they can culture microorganisms. After three and six weeks they make observations of the mud and the organisms growing in it. In this way they observe succession and relate this to deep-sea chemosynthetic communities. To conclude, they write an essay on the importance of deep-sea organisms. The write-up does not include a lab sheet, but rather, it uses class discussion as a way to process observations and knowledge gained.
Meant to be a simulation of a deep-sea exploration, this requires that another lesson be completed first. In that lesson, titled "Animals of the Lost City," marine biology buffs construct murals of benthic communities. In this lesson, the organisms are covered with sticky-notes, to be removed systematically by other learners as they imagine they are using an autonomous underwater vehicle. Find the preceding lesson via the Lesson Planet website or your own internet search.
Students explore current events by reading about a trip to the bottom of the ocean. In this modern day explorer lesson, students read about Virgin CEO Richard Branson and his adventure to the bottom of the ocean. Students complete several worksheets including true/false and synonym matching activities based upon the story.
Analyze and graph oxygen isotope ratios in coral samples in relation to the distance from the outer skeleton edge. Compare the data to the mean monthly water temperatures. Uncover whether or not there is any correlation. In addition to instructions and handout for the activity, there are several resource links to background information and details on the associated Trondheimsfjorden expedition, during which this data was collected. Use this in your high school biology class.
Practice reading comprehension by approaching oceanography through 2 pages of informational text. The text compares the ocean floor to the Grand Canyon to gives students perspective, and gives a brief coverage of the earth's crust and ocean floor characteristics. Ten true/false questions follow, prompting students on direct recall and comprehension. To add interest, consider some pre-reading activities, such as guessing words that will appear in the text!
Students describe major features of cold seep communities and list organisms that are found in these communities. For this water habitat lesson students examine trophic levels, describe the process of chemosynthesis and list the organisms that are found in these habitats.
