Big Brain Shows Lesson Plan Episode 16 • March 4, 2026

Satellites, Super-Plants, and a Spiky Sea Surprise

Main Lesson Takeaway

"Science and technology help us explore, connect, and protect our world—from satellites in space to helpful plants and newly discovered ocean animals."

The Hook (Pre-Watch)

Ask the class before watching:

"How do you think humans can learn about things we can’t easily see up close—like the internet traveling through space, chemicals inside plants, or hidden differences between ocean animals?"

Vocabulary Focus

orbit

An orbit is the path something takes as it goes around a planet in space.

If a satellite stays in the same orbit, it can keep circling Earth and sending signals to help people connect to the internet.

conserving

Conserving means protecting something and using it carefully so it doesn’t run out.

Conserving wild mint and lavender helps those plants keep growing so people and animals can use them in the future.

species

A species is a group of living things that are very similar and can have babies like themselves.

Scientists get excited when they find a new species because it teaches us more about life in the ocean.

DNA

DNA is the tiny set of instructions inside living things that helps make them what they are.

Even when two sea creatures look alike, their DNA can show they are actually different.

Discussion & Reflection

Have students answer these questions after watching the episode.

1
Where do you think satellites “park” in space, and why?
2
What’s one plant you use at home (food, smell, medicine), and how do you think it grows in nature?
