We went there as a homeschool trip and it was amazing!!!! They had a program about getting in for free if you use the BART, however, I think it's very well worth the entrance fee that they charge! There are LOTS of exhibits! We were there the whole day and I don't think we really saw everything! The cool thing is, it is truly an "explorer" museum! You can touch and try everything. You don't even need to whisper! A very educational and fun place! We went with kids ages 4-12 & everyone enjoyed it. We are going back again soon!!!
