This is a great place to hang out with your kid, especially if the weather is too cold/hot/windy/rainy for outdoor fun. I've been twice with my son at ages 4 and 5, and it was very engaging for a long period of time. We went a year or so ago with a friend for a few hours and stayed on after our friends left to eat ice cream in the cafeteria and see a couple more things. After 4 or 5 hours, we still hadn't done/seen everything. Then we were just there last weekend. A few exhibits had moved or changed, and we spent a good 3.5 hours inside the museum and could easily have stayed longer if they weren't closing.
My kid loves many things in here. In a little kid room they have a vertical wind tunnel that you put lightweight cloths in and watch them go up to the ceiling, a vortex/funnel that balls roll around in until they drop down, and a pin board where you can push pins back and forth and make patterns, handprints, etc. There is a wall board in the main hall where you can press cards into slats to make a ramp for balls. Downstairs there is a row of math/logic puzzles like Tower of Hanoi to sit and play. In the bigger kid room, you can play physics games (currently they have skee ball and pinball), build a track/ramp for balls to roll on, or (one time we were there) make a parachute and try it out in a wind exhibit. In the lobby area, you can build with Keva blocks or test out animation. And there are many, many more things to do.
I think this place appeals to a wide range of ages. A toddler can find fun things in the little kid area, and beyond. A five-year-old is in pig heaven. There were plenty of older kids having a ball. But adults and teens wouldn't want to go here expecting an adult museum experience - this is primarily a children's museum with interactive exhibits designed to peak a child's curiosity and show them how playing fun stuff links to science.
Some info:
1. If the parking lots look full, go into the closer lot and drive up the driveway to the terraces of parking above. Make sure you know your license plate number for the machine below.
2. Expect to spend a half hour outside on the whale and the DNA model if your kid likes to climb. Expect it to be very, very windy. Parents can enjoy the awesome view on a clear day.
3. The store is within the paid area of the museum, but I asked and was allowed to go into the store only, without paying first. Great place to go holiday or birthday shopping for a kid.
4. The cafeteria has awesome views and you can bring your own food and eat there if you want.
The upstairs is remodeled and looks relatively modern, but the downstairs looks like someone forgot to update it -- has that 50s government or school building feel. To me this is great. I never have to worry about my kid tearing up the place, because it's already worn. The two birthday party rooms are downstairs and don't expect them to be cheery or decorated -- they are interior classroom type spaces -- but they are completely functional with tables and chairs.
Overall, I really like this children's science museum. It's pricey, but not at all compared to similar places like Chabot, Exploratorium, etc. It's comfortable, and I always feel like it can sit on the floor with my kid or find a place to park my stuff. The coat check area is not attended, but you can easily hang your coat or put some stuff on a shelf -- but beware, anyone can go in there, so don't leave valuables. I always feel safe at this museum, though; it is contained, and not near anything else.
