The big idea
Nebulae are clouds of gas and dust with different origins; some are active star-forming regions.
Gravity can gather cold dense parts into new stars, while radiation from young stars shapes surrounding material.
◉
HOW SCIENTISTS KNOW
Infrared, radio and visible observations reveal dust, molecules and newborn stars.

!A COMMON WRONG MODEL
Nebulae and Star-Forming Regions is only a name or picture to memorize.
✓REBUILD IT WITH EVIDENCE
Connect nebulae and star-forming regions 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 nebulae and star-forming regions using nebula and gas.

Three things to remember
✓Nebulae are clouds of gas and dust with different origins; some are active star-forming regions.
✓Gravity can gather cold dense parts into new stars, while radiation from young stars shapes surrounding material.
✓Evidence matters: infrared, radio and visible observations reveal dust, molecules and newborn stars.
