To have a quiet drone that protects endangered animals like rhinos

Ultra-Quiet Propulsion

You’ve chosen to imagine a quiet drone watching over endangered animals like rhinos without scaring them. You might want to learn more about ultra-quiet propulsion, which helps flying machines make much less noise. Just don’t get startled when the drone appears out of nowhere to rescue you!

Fun Facts:

Whisper Aero has built an electric drone engine that it claims produces less than 37 decibels—roughly the noise level of a soft whisper—from 100 feet away.
In a South African study, low-flying drones caused white rhinos to move away, showing why quieter wildlife drones could matter.
After World War II, the U.S. Fish and Wildlife Service used old military airplanes to count wildlife in remote places—an early version of watching animals from the sky.

Ultra-Quiet Propulsion

LISTEN

We’re exploring ultra-quiet propulsion, which helps flying machines make less noise. Propellers and motors can produce sounds that disturb animals, so engineers are designing quieter motors and fans to soften that sound. Scientists also test how different animals react when drones fly overhead. Quieter drones could watch wildlife while interfering less with their lives. Just don’t get startled when the drone appears out of nowhere to rescue you!

Fun Facts:

The WildDrone research project is testing drone sounds against different animals’ hearing so researchers can design flights that disturb wildlife less.
Whisper Aero says its eQ160 electric engine is designed for small drones and can stay under 37 decibels—roughly the noise level of a soft whisper—from 100 feet away.
U.S. Geological Survey researchers found that sea otters reacted more strongly when a drone flew closer to them.
Researchers used a drone to monitor Western Grebe nests while reducing the need for people to enter the birds’ nesting area.
Wildlife scientists were using airplanes long before drones: the U.S. Fish and Wildlife Service began regular aerial wildlife surveys with surplus aircraft in the late 1940s.

Discussion Question:

What would you change about a wildlife drone to make animals feel safer around it?

LISTEN

Physical Build:

Build your own quiet wildlife drone from cardboard, paper, bottle caps, and tape. Add pretend cameras or sensors, then redesign the propellers to make them look quieter. Place paper animals nearby and decide how high your drone should fly so it can observe them without getting too close.

Digital Build:

With an adult, ask ChatGPT:

“Design a super-quiet drone that watches endangered animals without disturbing them.”

Choose the features you like, change anything you do not, then draw or build your own version. Decide what your drone should notice—and what it should leave alone.

or a drone that puts out forest fires?

Firefighting Drone

First-Responder Drones

LISTEN

You’ve chosen to imagine drones racing toward a forest fire and helping stop it before it grows. You might want to learn more about first-responder drones, flying robots designed to help during emergencies. Do robot firefighters wear those red hats, too?

Fun Facts:

Airplanes were helping spot forest fires more than 100 years ago: U.S. Army pilots began patrolling Oregon forests for fires in 1919.
In California in 2025, an autonomous Black Hawk helicopter found test fires and dropped water on them with no pilot touching the controls.
Rwanda began using drones to deliver emergency blood to hospitals in 2016. These drones can make some four hour trips in just 15 minutes.

First-Responder Drones

LISTEN

We’re exploring first-responder drones, flying robots built to help during emergencies. Small drones already help map fires, locate hot spots, search for people, and show responders where danger is spreading. Larger experimental aircraft can carry water or other equipment, entering areas too dangerous for humans. But human teams remain responsible for coordinating operations and making safety decisions. Future teams may combine people, drones, helicopters, and ground crews together. Wait…do robot firefighters wear those red hats, too?

Fun Facts:

In 1919, U.S. Army Air Service pilots flew above Oregon forests looking for smoke and reporting new fires to crews below.
Rwanda began using drones to deliver emergency blood to hospitals in 2016. In some remote areas, trips that once took up to four hours could be completed in about 15 minutes.
Search-and-rescue teams can use heat-sensing drone cameras to spot missing people at night.
During a 2025 California test, an autonomous Black Hawk carried a 324-gallon water bucket and made targeted drops on test fires.
After hurricanes and floods, transportation agencies have flown drones over damaged roads and bridges before sending people in. The aerial views can help crews decide what is safe to reopen.

Discussion Question:

What might change if firefighting drones could reach a new fire within minutes?

LISTEN

Physical Build:

Build a firefighting drone from cardboard, cups, string, paper, and tape. Add a pretend water tank, camera, and hose or bucket. Then make a paper forest with one small “fire” marked in orange and test where your drone should release its water without soaking everything nearby.

‍

Digital Build:

With an adult, ask ChatGPT:

“Design a firefighting drone that can find a tiny forest fire and safely stop it before it spreads.”

Look at the ideas, then redesign the drone your way. Draw where it stores water, how it finds smoke, and how it works with human firefighters.
