Complete Concept Guide (100% Curriculum Coverage)
1. The Illegal Smuggler in Space
Sven Olsen, an astronaut aboard an orbital space station, secretly smuggles a yellow canary named Claribel onboard. In zero gravity, Claribel learns to fly in place like a hummingbird without flapping her wings!
2. The Morning Headache
One morning, the narrator wakes up with a throbbing headache and sluggish senses. Breakfast is delayed because Claribel is found unconscious, lying on her side with her claws curled in the air!
3. The Broken Circuit
The crew revives Claribel with an oxygen mask. The narrator suddenly remembers: Canaries were taken into coal mines because they are hyper-sensitive to toxic air! They inspect the space station's air monitors: a frozen valve had failed, and the computerized electronic alarm had failed to sound! Claribel saved the entire crew's lives.
