I've done an interactive "do you know how many types of engineers there are?" for this age group that's worked really well. Timeframe: 5-15 minutes
"Can anyone name a type of engineer?" and for each shoutout, talk a little about what each does. The guessing keeps everyone's attention.
Types: software/computer, electrical, mechanical, chemical, environmental, civil, nuclear, aeronautical, etc.
Bonus: bring 2-3 props (your drones would be GREAT) that you can hold up for the relevant flavor.
For drones, I like to ask: "how do you think the drone moves forward?" [over power the rear two, underpower the front] Same Q for other directions.
"how do you think it rotates?"
"why don't all props spin in the same direction?"
Bring one of these to fly in the room: https://www.amazon.com/Cheerson-CX-10-Diameter-2-4GHz-Quadco...
Talk about how there's actually a computer on board.
If you have access to a TV, bring a short ~2min drone POV video to show.
Tell bad jokes ("Civil engineers are very nice to each other", etc.) Google online for some.
It's all about energy and making it interactive.
