HS Science Program Recs

Hi everyone,
I was wondering if anyone has any recommendations for science programs/competitions for high schoolers. I see a lot of talk around high-competition high-prestige programs like RSI and Siemen’s but I am feeling sort of overwhelmed. I thought I could ask for maybe some popular lower prestige programs that could serve as a starting point. I hope one day I can get to RSI but not anytime soon, lol. Thanks so much!

If you participate in your school’s Science Olympiad team you may be able to earn a regional or state-level award
