Órnaith,
Please do register your class (or school) event at Space Week. The event can be the activity you plan for your class and does not need to be a public event for others to attend, although you may want to invite parents to visit the class to share the Space adventure their children have been on during the week.
You can register at https://www.spaceweek.ie/add/
If you would like to apply for a slot for ESERO Space Goes to School, which matches a speaker to a school, you can register your interest here: https://www.spaceweek.ie/for-organisers/for-teachers/space-speaker-in-your-classroom/
