Oh GeoMama...
Can you find the first presenter and chat a bit to see if he or she would do more on a drop in basis?

Keep looking and I do believe you will find some mixed age groups that have content. Our local Chess club is outstanding and I've seen 5 year olds there. Try nature centers or rock hounds or train enthusiasts or reptile clubs or weather clubs. Anything aimed at adults that allows kids will usually have content and a few kids. Good luck.
