Big Brain Shows Lesson Plan Episode 11 • February 26, 2026

Mars Maps, Mystery Fish, and a House Full of Ideas!

Main Lesson Takeaway

"Explorers use creative tools and careful observations—like robots, maps, and experiments—to solve problems and learn about places humans can’t easily reach."

The Hook (Pre-Watch)

Ask the class before watching:

"If you had to explore a place people can’t safely go (deep ocean, outer space, inside a volcano), what tool or robot would you invent, and how would it help you find answers?"

Vocabulary Focus

orbit

To travel in a looping path around something, like a planet.

The spacecraft can orbit Mars and take pictures that help the rover figure out where it is.

location

The exact place where something is.

If the rover knows its location, it can drive faster and avoid getting lost among the rocks.

pressure

A pushing or squeezing force on something.

Deep in the ocean, the pressure is so strong that animals need special bodies to handle the squeeze.

species

A group of living things that are alike and can have babies like themselves.

When scientists discover a new species, it’s like adding a brand-new page to Earth’s nature book.

Discussion & Reflection

Have students answer these questions after watching the episode.

1
If you could design one room in a “show house,” what theme would you pick and why?
2
How do robots help humans explore places that are too hard to visit?
