The big idea
Spacesuits are personal spacecraft that provide pressure, oxygen, temperature control, communication and protection.
They must keep an astronaut alive while still allowing movement and useful work.

HOW SCIENTISTS KNOW
Vacuum-chamber, mobility and life-support tests verify each suit before use.

!A COMMON WRONG MODEL
Spacesuits and Life Support is only a name or picture to memorize.
✓REBUILD IT WITH EVIDENCE
Connect spacesuits and life support to the observable relationship, evidence and system described in the lesson.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Try it together
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 spacesuits and life support using spacesuit and pressure.

Three things to remember
✓Spacesuits are personal spacecraft that provide pressure, oxygen, temperature control, communication and protection.
✓They must keep an astronaut alive while still allowing movement and useful work.
✓Evidence matters: vacuum-chamber, mobility and life-support tests verify each suit before use.
