Big Brain Shows Lesson Plan Episode 78 • June 25, 2026

Fast Rockets, Talking Robotaxis, and Sun Festivals

Main Lesson Takeaway

"Technology and traditions both help people work together—whether it’s machines communicating clearly for safety or communities celebrating history to stay connected."

The Hook (Pre-Watch)

Ask the class before watching:

"What are some ways we communicate “what we’re going to do next” (with words, signs, or actions), and why does that matter in places like streets, teams, or celebrations?"

Vocabulary Focus

responsive

Able to react quickly when something changes or when help is needed.

After a big storm, a responsive satellite launch could help people get new weather pictures fast.

orbit

The path something takes as it travels around a planet or moon.

The satellite stayed in orbit, circling Earth again and again to send information down to scientists.

sensors

Tools that help a machine notice what is happening around it, like seeing or measuring distance.

The robotaxi used sensors to detect a bike nearby and slowed down to stay safe.

reenactments

Performances where people act out events from the past to help others remember history.

During the festival, reenactments helped the crowd learn what life was like long ago in the Andes.

Discussion & Reflection

Have students answer these questions after watching the episode.

1
If a robot car could talk, what should it say to help people feel comfortable crossing the street?
2
What’s one tradition your family has, and what does it celebrate?
