Big Brain Shows Lesson Plan Episode 92 • July 29, 2026

Space Slingshots, Sunrise Fish, and Smart Patches

Main Lesson Takeaway

"Scientists use careful observation, planning, and testing to learn from space, ocean life, and the human body."

The Hook (Pre-Watch)

Ask the class before watching:

"If you could study one thing closely today, would you choose a spacecraft, a reef fish, or a health patch, and why?"

Vocabulary Focus

gravity assist

A spaceflight method where a spacecraft uses a planet’s gravity to help change its speed or direction.

Psyche used a gravity assist when it flew past Mars on its journey to an asteroid.

time-lapse

A video made from pictures taken over time and played quickly so slow changes look faster.

The Psyche team captured a time-lapse video during the Mars flyby.

species

A group of living things that scientists identify as the same kind of organism.

Researchers described a new species of shrimpgoby from waters around Indonesia.

body signal

Something the body does that can be measured, such as a heartbeat signal or movement pattern.

The wearable patch is designed to collect more than one body signal into a single data stream.

Discussion & Reflection

Have students answer these questions after watching the episode.

1
If you were planning a spacecraft trip, why might using a planet’s gravity be helpful?
2
The episode says: “NASA’s Psyche spacecraft used Mars’s gravity like an invisible slingshot to help change its speed and direction on the way to a metal-rich asteroid.” What would you like to learn more about?
3
The episode says: “A small reef fish called a shrimpgoby was officially described and named with inspiration from the orange colors of Java’s sunrise.” What would you like to learn more about?
