In this lesson, students embark on an adventurous journey to explore the depths of the ocean, discovering various marine life and ecosystems at different depths. From vibrant coral reefs and apex predators like orcas to the mysterious creatures of the abyss, the lesson highlights the incredible diversity and challenges of deep-sea exploration, culminating in the Challenger Deep, the deepest known point in the ocean. The experience encourages curiosity and a sense of wonder about the ocean’s unexplored territories.

Exploring the Deepest Parts of the Ocean

Have you ever wondered what it’s like to dive into the deepest parts of the ocean? Today, we’re going on an exciting journey to explore the ocean’s depths! Don’t worry if you can’t hold your breath for long—just hop aboard our submersible craft and let’s dive in!

Starting the Adventure

As we begin our dive, just below the surface, you’ll notice that the ocean is full of life. Fish and marine animals are everywhere, and you might even see some swimmers waving at us. But we’re not stopping here—let’s go deeper!

Discovering New Depths

At 65 feet, we see beautiful shallow coral reefs. Scuba divers are exploring here, but they can’t go much deeper without special equipment. At 130 feet, we say goodbye to recreational scuba divers as this is their maximum depth.

At 200 feet, we meet our first orca, a type of whale that is an apex predator, meaning it has no natural enemies. At 230 feet, we see whale sharks, the largest fish in the ocean, which can live up to 130 years!

Into the Darkness

As we dive deeper, at 330 feet, only professional divers can be found. At 490 feet, just 1% of the surface light reaches us, and it gets darker as we go. At 660 feet, we might spot a giant oarfish, a creature that inspired sea serpent legends.

Meeting Strange Creatures

At 980 feet, we encounter a Japanese spider crab with long legs. At 1,640 feet, we see the last of the blue whales, the largest creatures on Earth. They can dive deep, but they usually stay in shallower waters for food.

At 2,723 feet, we’re deeper than the tallest building in the world, the Burj Khalifa, if it were underwater. At 2,950 feet, we might see a giant squid, a legendary creature with eyes the size of frisbees!

The Midnight Zone

At 3,600 feet, we find West Mata, one of the deepest ocean volcanoes. At 4,200 feet, great white sharks swim, and leatherback turtles dive. At 4,900 feet, we see huge fishing nets used to catch fish on the ocean floor.

At 6,600 feet, we might spot the black dragonfish, a creature that looks like it’s from a horror movie. At 7,400 feet, we say goodbye to sperm whales, the largest toothed whales in the world.

Reaching the Abyss

At 9,900 feet, we see deep-sea coral reefs. At 12,100 feet, we reach the average depth of the World Ocean. Below this, we enter the Abyss, where the scariest creatures live, like the anglerfish and the black swallower.

At 18,900 feet, we find the deepest shipwreck, the SS Rio Grande. At 19,700 feet, we enter the Mariana Trench, the least explored part of the ocean.

The Bottom of the Ocean

At 26,000 feet, we meet the snailfish, the deepest fish ever found. Finally, at 35,853 feet, we reach the Challenger Deep, the very bottom of the Earth. Few people have been here, and there’s still so much to learn.
