The big idea
The Milky Way is a barred spiral galaxy containing the Sun and hundreds of billions of stars.
The Solar System lies in its disk, far from the center; dark lanes of dust cross our view from inside.

HOW SCIENTISTS KNOW
Star mapping, radio observations and the motions of stars and gas reveal its structure.

!A COMMON WRONG MODEL
The Milky Way is only a name or picture to memorize.
✓REBUILD IT WITH EVIDENCE
Connect the milky way 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
Place Moon, Sun and galaxy cards at increasing distances along a room or hallway. Walk from Earth to each and connect distance with light-travel time. Connect what you notice to the milky way using Milky Way and galaxy.
