Students and teachers are encouraged to participate in a global campaign to observe and record the magnitude of visible stars as a means of measuring light pollution in a given location. GLOBE at Night is an easy observation and reporting activity that takes approximately 15-30 minutes to complete. Students should be encouraged to participate with their parents or families in this global campaign.
Please remind students of the following safety guidelines:
- Be sure you ask for permission from your parent(s) or guardian to go outside after dark to do this activity. This is designed to be a family activity, invite all your family members to do the activity with you.
- Depending on your location, be sure to wear suitable clothing for the weather and for being outside at night (light colored and/or with reflective colors).
- Remember safety first! When choosing the darkest area in your location, be sure the location is not close to traffic, the edge of a balcony, or near any other type of danger.
Try these glow-in-the dark activities for finding Orion, Leo & Crux in your night sky, Orion at Your Fingertips*: English, Spanish, Leo at Your Fingertips*: English & Crux at Your Fingertips*: English.
Light pollution impacts more than just the visibility of stars at night. Many living things are impacted by artificial light at night. Learn more about light pollution as background information for this activity.
If your students enjoyed this activity, they may be interested in doing multiple observations by moving to a new location at least 1 km away from their original location. Remind them to get new latitude and longitude coordinates. This can be done on the same night or on another night any time during the dates of the campaign.
Learning Objectives - Students will be able to:
- Use latitude and longitude coordinates to report the location of their observation
- Locate the constellation Orion using stellar maps
- Determine the magnitude of the faintest visible stars in their location
- Analyze the spatial data collected
- Draw conclusions from studying the mapped observations
