Activity 01
Stations Rotation: Star Brightness Stations
Prepare stations with varying light sources at different distances to mimic star brightness. Students measure perceived brightness with light meters or drawings, then discuss how distance affects appearance. Rotate groups every 10 minutes, culminating in a class chart comparing real stars.
Explain why stars appear to move across the night sky.
Facilitation TipDuring Star Brightness Stations, place dimmer lights farther from students to emphasize that distance changes apparent brightness more than actual size.
What to look forProvide students with a list of five star names and their apparent magnitudes. Ask them to rank the stars from brightest to dimmest as seen from Earth and write one sentence explaining why a star might appear dimmer even if it is very large.
