ClassX Video Lessons Youtube Channel Next Generation Science Lighthouse Lab – Chels Explores the Deep Sea – Part 1
Welcome to an exciting adventure beneath the waves! Today, we’re joining Chels as she explores the mysterious world of the deep sea. Let’s dive in and see what incredible creatures we can find!
Chels is all set to go on her deep-sea adventure. She checks in with the control center to make sure everything is working perfectly. Once she gets the green light, it’s time to start the descent into the deep ocean.
As Chels descends to 400 meters, she spots something unusual. It’s a chimera fish! These fascinating creatures, also known as ghost sharks or ratfish, have long bodies, big eyes, and spines that can be venomous. They live in the deep sea, usually between 200 and 2500 meters below the surface. Chels makes sure to record this amazing find in her database.
Continuing her journey to 600 meters, Chels sees another strange fish. It’s a barrel eye fish! This fish is known for its see-through head and tubular eyes that can look upwards. This special feature helps it spot prey swimming above. Barrel eye fish are also found at depths of 200 to 2500 meters. Chels adds this discovery to her records.
As Chels descends further to 800 meters, she notices something small but intriguing. It’s a vampire squid! These creatures are not like regular squids. When they feel threatened, they can turn their arms inside out to form a spiky ball, which is called the pineapple posture. This helps them stay safe from predators. Vampire squids usually live between 600 and 900 meters deep.
Chels is eager to explore even deeper waters. She asks for permission to descend to 1,000 meters. With everything running smoothly, she continues her journey, excited to see what other wonders the deep sea holds.
The deep sea is full of amazing and mysterious creatures, and Chels is on a mission to discover as many as she can. Stay tuned for more adventures as she continues to explore the ocean’s depths!
Imagine you are a deep-sea explorer like Chels. Design your own deep-sea creature! Think about its features, how it survives in the deep ocean, and what makes it unique. Draw a picture and write a short description of your creature’s habitat and behavior.
Choose one of the creatures Chels discovered: the chimera fish, barrel eye fish, or vampire squid. Research more about your chosen creature and create a poster that includes interesting facts, its habitat, and any special adaptations it has for living in the deep sea.
Work in groups to simulate a deep-sea exploration. Assign roles such as the explorer, control center operator, and data recorder. Use classroom materials to create a model of a deep-sea environment and act out a discovery, recording your findings just like Chels.
Write your own adventure story about exploring the deep sea. Include at least two creatures Chels encountered and describe an exciting discovery or challenge you face during your exploration. Share your story with the class.
Create a comparison chart for the chimera fish, barrel eye fish, and vampire squid. Include categories such as depth range, physical features, and survival adaptations. Discuss with your classmates how these creatures are similar and different.

Can you hear me loud and clear? Great, all systems normal.
Pilot to Control: You’re good to go.
Copy that, Pilot to Control Center: Preparing to descend.
[Music]
Thank you.

The Lighthouse Lab: Hey there! As you might have guessed, I’m not in the lab today. Instead, I’m going on an adventure to discover and document what creatures live in the deep sea. Here we go!
Pilot’s Control Center: Descending.
Copy that, proceeding to 400 meters. Nice and slow.
Approaching 400 meters.
Whoa, are you getting this? What’s that? A chimera?
Yeah, sure is! Great work! Please confirm and create a database record.
Identification confirmed: A chimera fish, also known as a ghost shark or ratfish, is a type of cartilaginous fish found in deep sea environments at depths ranging from 200 to 2500 meters. Chimera fish are known for their elongated bodies, large eyes, and venomous spines on their backs and tails.
All systems normal. Proceed to 600 meters.
Copy that, heading to 600 meters.
On your right, is that—no way! It’s a barrel eye fish! I never thought I’d see one of these guys. What a strange-looking fish!
Please confirm and create a database record.
Identification confirmed: A barrel eye fish, also known as a spookfish, is a type of deep sea fish named for their distinctive tubular eyes, which are pointed upwards and can rotate within their transparent head. This helps them spot prey above them. They are typically found at depths of 200 to 2500 meters.
You’re clear to keep descending to 800 meters.
Copy that.
I’ve got something; it’s pretty small. Zooming in for a closer look.
Yup, thought so—it’s a vampire squid!
Great work! Well spotted! Have you got this identification confirmed?
The vampire squid is a small deep sea cephalopod typically found at depths of 600 to 900 meters. When threatened, they can invert their webbed arms to create a spiky ball shape called a pineapple posture, which helps protect them from potential attackers.
Pilot to Control: Requesting permission to descend to 1,000 meters.
Copy all systems normal. Proceed at a steady pace.
Just copy that.
There’s something pretty big down there.
