Where Did They Come From?
Give science learners nine questions about the biogeography of hydrothermal vents and turn them loose to research this fascinating habitat. Working in cooperative groups, they prepare a report that addresses each of the questions. A...
NOAA
A Quest for Anomalies
Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson in a series of five. Scholars examine data and look for...
NOAA
The Oceanographic Yo-yo
How does chemistry help deep-sea explorers? Part four of a five-part series of lessons from aboard the Okeanos Explorer introduces middle school scientists to technologies used in ocean exploration. Groups work together to analyze data...

Chemosynthesis and Hydrothermal Vent Life
What's life like in a hydrothermal vent? Find out in part five of a 13-part series. Learners journey to one of the harshest environments on the planet, the hydrothermal vent, to learn about the creatures that survive the extreme...

Where There's Smoke, There's ...
A remotely operated vehicle approaching a volcano was engulfed by molten sulfur where the plumes of fluids contained the highest concentrations of aluminum ever recorded. This isn't science fiction or an April fools joke, though it did...

Animals of the Fire Ice
When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

Deep-Sea Ecosystems – Entering the Twilight Zone
Imagine an ecosystem without any light or oxygen, where living things convert carbon dioxide into food. This ecosystem is thriving and might just be the largest ecosystem on our planet, yet we know very little about it. The lesson...
NOAA
Community Ecology and Sampling
Seamounts in the Coral and Tasman Seas are home to more than 850 different species. Groups explore hydrothermal vents, researching the organisms found there and their energy source. They also learn about seamounts, exploring their unique...
NOAA
Individual Species in the Deep Sea
A tube worm's outer covering is made of chitin, the same material that makes up the shells of lobsters and crabs. Scholars create tube worms and analyze and discuss the longevity of organisms living near cold seeps. They then discuss and...
NOAA
The Biggest Plates on Earth
The deepest part of the ocean is the Marianas trench where two tectonic plates meet. Scholars explore plate tectonics and their boundary types by completing hands-on activities throughout the lesson. Specific areas, such as the Galapagos...

Technology I
Isn't technology great? The 12th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces technology that marine scientists use. Pupils take part in an activity using conductivity,...
Curated OER
Animals of the Lost City
Begin with a demonstration of exothermic reactions and discussion of chemosynthesis. Your aspiring oceanographers research vent communities and then craft a mural of a vent community. This is a terrific method of introducing learners to...
Curated OER
Towers of the Lost City
Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...
Curated OER
Where's Dinner?
Upcoming marine biologists consider a list of organisms residing near the Lost City hydrothermal vents and construct a food web. They compare the food web to that of a cold seep community, of which they should have previous knowledge....

Hydrothermal Vent Challenge
Give our ocean voyagers the "Hydrothermal Vent Challenge!" It is a worksheet that guides them through an exploration of hydrothermal vents and the chemical reactions that occur when lava meets seawater. Using a collection of websites,...
Curated OER
What's for Dinner?
View a video presentation comparing chemosynthesis to photosynthesis. Review the findings of the 2004 Ring of Fire Expedition that studied biological communities around the hydrothermal vents of the Mariana Arc. In collaborative groups,...

Mystery of the Megaplume
Read through the extensive background information and then lead your geology or physical oceanography class through an investigation of actual temperature anomaly data from the Juan de Fuca ridge. They translate the data onto a plot,...
Curated OER
What's That?
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,...

Life is Weird
Separate your science class into small groups and assign each a specific deep-sea organism to research. The class will learn about all of the organisms as each group presents their assigned animal. Following their presentations, you can...
