Summer programs for current 9'th graders

Hello all,

Most summer programs seem to be sophomores and higher. Any recommendations for what summer programs or activities that will really help ? I am interested in STEM activities particularly.

CTY residential summer camps
If under 14 yo, MathPath; if over 14, MathCamp
Most science museums have summer programs
Most math circles have summer programs

I am 14 years old. CTY seem to be pretty expensive. Could you share some links to MathCamp ? My HS will not give credit for any online courses as well.

@GoBears2023 Any suggestion for STEM related summer programs for rising sophomores?
