Summer of freshman year?

Hello CC people,
I’m almost finish with freshman year in hs. I’ll have a 4.0 uw gpa by the end of this semester. But I don’t know what to do during summer?!!
Ok so this is my plan:
-I’m taking Spanish at Community College.(So I’ll be moving to Spanish 3 when I’m a soph)
-I’m taking SAT prep courses.
-I’m volunteering for my local library.
-Also I’m in Girl Scouts.
I love STEM!! But I’m not doing any activities relevant to it!!
Can u guys suggest some camps/activities/workshops/etc?
Not just for this summer but for other summers as well! I need some help here! Thanks

you can do robotics (look up First Tech Challenge)
