![]() ![]() For example, if they listed that the hadalpelagic zone is dark, they might include adaptations such as acute hearing or sonar to aid in navigation and/or the loss of eyesight because it would be of little use in that environment. Ask them to also consider adaptations related to senses or physical characteristics that would not be needed there. Have students brainstorm adaptations related to the characteristics of the hadalpelagic zone.įor each characteristic of the hadalpelagic zone that students listed on the Deep-Sea Creature Project Planner worksheet, have them brainstorm possible adaptations that would allow an animal to survive and thrive in a place with that characteristic. Have them list unique characteristics of the hadalpelagic zone in the first column of the worksheet.Ĥ. Have students read the information about the Mariana Trench from the provided DEEPSEA CHALLENGE, Windows to the Universe, and NOAA Layers of the Ocean websites. ![]() Have students investigate the hadalpelagic zone.ĭistribute the Deep-Sea Creature Project Planner worksheet to each pair of students. Then have them compare the lists of characteristics and adaptations to the different ocean zones to predict in which zones the creatures live.ģ. Have students look at the photos of the animals, read the captions, and list as many characteristics and adaptations of the animals as they can. Give each pair of students a photo of an ocean animal from one of the provided websites or point them to an animal on one of the websites. Divide students into pairs and have them review the characteristics of the ocean zones and match ocean animals with the ocean zones in which the animals are found.īriefly review the characteristics of each ocean zone, using the provided NOAA Layers of the Ocean website if necessary to refresh students’ memories. Ask: Could Cameron (or any person) survive under that much pressure at those depths without being protected inside of something? Could other living creatures survive at those depths and that pressure? How? What other living creatures do you think Cameron was likely to encounter at those depths?Ģ. Activate prior knowledge by introducing or reintroducing James Cameron’s historic Challenger Deep dive.Įxplain that Cameron’s submersible was under 8 tons of pressure per square inch while he was in the Challenger Deep at depths of up to 10,898 meters (35,756 feet). ![]()
