Nicola,
Stellarium is a powerful tool and children can use it on their own. We have used it to show the effects of light pollution and to give children a scavenger hunt of objects to find. A similar hunt is here: https://pacificsciencecenter.org/wp-content/uploads/2024/01/cah-sky-search.pdf
With older students we have used it to plan observing sessions (similar to this: https://www.schoolsobservatory.org/sites/default/files/discover/stemclubs/secondary/NSO-Secondary-Silver-S4-PlanningObs.pdf)
We produced a guide to using Stellarium to find Messier Objects for Space Week 2023, see here: https://www.spaceweek.ie/space-week-resource-pack-2023/
And, it is part of our outreach StarDome experience, where participants are seated in the inflatable dome with Stellarium projected onto the interior of the Dome.
