Hohonu Moana: Exploring Deep Waters off Hawaiʻi






Lessons

Below, you will find lessons and learning tools relevant to the expedition and the exploration strategy of the Okeanos Explorer.


Exploring LIVE with the NOAA Ship Okeanos Explorer (Grades 5-12)

(PDF, 169 KB)

Focus: How students can become active ocean explorers while viewing live video feeds during Okeanos Explorer expeditions (Physical Science/Earth Science)

Students learn how to access the Ocean Explorer website and access a live video feed of an Okeanos Explorer expedition; explore along with the ocean science community via live feeds during Okeanos Explorer expeditions; and track an expedition using the Okeanos Atlas.

 

To Make an Archipelago! (Grades 6-8)

(PDF, 419 KB)

Focus: Formation of the Hawaiian Archipelago (Physical Science/Life Science)

Students describe eight stages in the formation of islands in the Hawaiian Archipelago and how a combination of hotspot activity and tectonic plate movement could produce the arrangement of seamounts observed in the Hawaiian Archipelago. Students also construct a scientific explanation based on evidence for how a combination of hotspot activity and tectonic plate movement could produce the distributions of cobalt-rich ferromanganese resources found in the Hawaiian Archipelago.

 

Cobalt-rich Ferromanganese Crust Ecosystems (Grades 9-12)

(PDF, 397 KB)

Focus: Ecosystems associated with cobalt-rich ferromanganese crusts (Physical Science/Life Science)

Students define cobalt-rich ferromanganese crusts, explain how they are formed, discuss their associated ecosystems, and discuss the positive and negative impacts of mining these mineral resources from the deep ocean. Students also evaluate possible design solutions for protecting ecosystems associated with cobalt-rich ferromanganese crusts from potential human impacts.

 

A Day in the Life of an Ocean Explorer (Grades 5-12)

(PDF, 635 KB)

Focus: Telepresence and communications for ocean exploration (Physical Science)

Students understand how telepresence technologies increase the pace, efficiency and scope of ocean exploration; and how the basic properties of simple waves contribute to processes of obtaining, evaluating, and communicating information in ocean exploration.

Wet Maps (Grades 5-6)

From the Okeanos Explorer Education Materials Collection, V2: How Do We Explore? (PDF, 904 KB)

Focus: Bathymetric mapping (Physical Science)

Students analyze and interpret data to explain how multibeam sonar is used to identify patterns of ocean floor structures; construct three-dimensional maps; and understand how multibeam sonar technology extends the measurement and exploration capacity of modern ocean exploration.

The Oceanographic Yo-yo (Grades 7-8)

From the Okeanos Explorer Education Materials Collection, V2: How Do We Explore? (PDF, 904 KB)

Focus: Ocean chemistry and hydrothermal vents

Students analyze and interpret data from the Okeanos Explorer to make inferences about the possible presence of hydrothermal vents; and explain how interaction with hydrothermal vents affects chemical and physical properties of seawater.

Through Robot Eyes (Grades 9-12)

From the Okeanos Explorer Education Materials Collection, V2: How Do We Explore? (PDF, 904 KB)

Focus: Image analysis

Students explain how robotic vehicle technology is used to extend the exploration capacity of scientific investigations aboard the Okeanos Explorer; use mathematics and computational thinking to show how lasers may be used in scientific investigations to calibrate images for size and distance measurements; and analyze and interpret video data from the Okeanos Explorer’s underwater robot to make inferences about environmental interactions of organisms in deep-sea ecosystems.

To further explore the exploration strategy of the Okeanos Explorer and the technologies of bathymetric mapping, water column exploration, and remotely operated vehicle imagery, view the lessons below.

Tools for Classroom Explorers – How to Use Multibeam Sonar Data (Grades 5-12)

From the NOAA Ship Okeanos Explorer Gulf of Mexico 2012 Expedition (PDF, 689 KB)
Focus: Multibeam sonar data and exploration activities during the NOAA Ship Okeanos Explorer Gulf of Mexico 2012 Expedition missions (Earth Science)
Students describe multibeam sonar, explain why the velocity of sound in water must be measured before maps can be created with the Okeanos Explorer’s multibeam sonar system, discuss the advantages of multibeam sonar bathymetry compared to two-dimensional topographic bathymetry, and interpret three-dimensional multibeam data of underwater features mapped by the Okeanos Explorer. This activity is followed up with Okeanos Explorer Multibeam Sonar Supplemental Datasheet #1 for Cruise 12.02 (pdf, 924 KB) in which students interpret three-dimensional multibeam data of underwater features mapped by the Okeanos Explorer during the Gulf of Mexico 2012 Expedition.

 

Tools for Classroom Explorers – How to Use CTD Data (Grades 5-12)

From the NOAA Ship Okeanos Explorer Gulf of Mexico 2012 Expedition (PDF, 867 KB)
Focus: CTD data and exploration activities during the NOAA Ship Okeanos Explorer Gulf of Mexico 2012 Expedition (Physical Science/Earth Science)
Students define "CTD" and explain how this instrument is used aboard the Okeanos Explorer; explain how relationships between temperature, salinity, pressure, and density in seawater are useful to ocean explorers; and use data from the Okeanos Explorer to create and interpret graphs of temperature, salinity, and depth. This activity is followed up with Okeanos Explorer CTD Supplemental Datasheet #1 for Cruise 12.02 (pdf, 956 kb) in which students interpret CTD data collected by the Okeanos Explorer during the Gulf of Mexico 2012 Expedition.

 

Tools for Classroom Explorers – How to Use ROV Imagery (Grades 5-12)

From the NOAA Ship Okeanos Explorer Gulf of Mexico 2012 Expedition (PDF, 1 MB)
Focus: ROV imagery and exploration activities during the NOAA Ship Okeanos Explorer Gulf of Mexico 2012 Expedition (Earth Science)
Students will describe typical applications and limitations of imagery obtained with ROVs, demonstrate how lasers may be used to calibrate images for size and distance measurements, and analyze ROV imagery from the Okeanos Explorer to make inferences about deep-ocean habitats and organisms. This activity is followed up with Okeanos Explorer ROV Imagery Supplemental Datasheet #1 for Cruise 12.02 (pdf, 837 kb) in which students interpret ROV imagery collected by the Okeanos Explorer during the Gulf of Mexico 2012 Expedition.
