The Discovery Science Center has some amazing, state of the art exhibits. My kids, 3 and 6, were enthralled with the high-tech Virtual Volleyball game, and they spent hours clambering about the life-size dinosaur exhibit, which was a feast for the senses! Unfortunately, the rest of the museum seemed a bit shopworn. Many, many of the exhibits were broken or not working properly. The entire kid's area was under construction and unusable - this was a big disappointment for us, given the ages of our kids, and we were unhappy that neither the website nor the staff at the ticket booth mentioned this beforehand (they had a makeshift area set up, but it only contained a few blocks and some Legos).
The crowds were a problem as well. Though it was a weekday, there were several large camp/school groups in attendance. The museum staff need more training in crowd management . . . I observed many kids crowding, pushing other kids aside, hogging exhibits and materials, etc.
Overall, my kids enjoyed themselves - they love being in a place where everything is hands-on. But my husband and I were left feeling that the experience was not quite worth the price of admission.
PROS: Some fantastic, unusual and state-of-the-art exhibits.
CONS: Too crowded and noisy, many exhibits broken or under construction.
