The big idea
A space station is an orbiting laboratory and home that must continuously support people and equipment.
Air, water, power, temperature, communication and waste are managed as connected systems.

The big idea
Air, water, power, temperature, communication and waste are managed as connected systems.
Long-duration missions measure station performance and human health in microgravity.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Build a paper mission card with a destination, science question, instrument, safety rule, power source and way to send results home. Connect what you notice to space stations and living in orbit using space station and orbit.
Check understanding
Choose the explanation that matches the evidence—not just the most familiar words.
