Have you ever watched a suitcase disappear on the airport belt and wondered, Where does it go now?
Harper and the Great Luggage Mystery
A STEM story about how suitcases travel behind the scenes
Harper is flying to Denmark-alone-for the very first time. She'll spend the summer with her cousin Freja, helping in the family bakery and exploring a brand-new country. But after Harper checks in her black suitcase and watches it slide away, she suddenly has a big question:
With so many people, planes, and bags... how does my suitcase know where to go?
Luckily, Uncle Ray works at the airport and has a little extra time before Harper's delayed flight. Together, they head off on a special behind-the-scenes tour to solve the great luggage mystery.
Kids follow Harper as she:
Prints a boarding pass and luggage tag at the check-in kiosk
Learns how the tag acts like her suitcase's name and address
Watches bags ride the luggage highway of conveyor belts and scanners
Sees how sorters and computers work together to send bags toward the right plane
Spots carts loading luggage into the cargo hold before takeoff
Sees the other side in Denmark, where bags ride one last set of belts to the carousel
By the time Harper finds her suitcase on the carousel in Copenhagen, readers will understand that airport luggage systems are not magic, they're a mix of smart machines, careful planning, and people who check everything along the way.
What kids will explore
How airports use barcodes, scanners, and conveyor belts to route luggage
Why luggage sometimes gets delayed-and how people catch problems before bags get lost
What happens from check-in counter to cargo hold to baggage claim
How it feels to be an unaccompanied minor and travel independently
