Perched on the mountains to the east of town, on the UC Berkeley Campus, is the Lawrence Hall Science Museum. This museum is a great place to take kids and has a number of kid friendly displays. The museum was named for Ernest O. Lawrence one of the inventors of the cyclotron particle accelerator. Hours are 10 AM to 5 PM. Make sure you get a ticket for parking from the machine by the entrance.
A great children’s science museum with outdoor sculptures of a whale and DNA that you can actually play on. The view of the bay from here is awesome. You can go to http://sv.berkeley.edu/view/index.html if you want an online version of the view right now.
This is a children's science education center named after the UC Berkeley physicist who invented the particle accelerator which led to the discovery of many radioactive elements. It is in a spectacular setting with great views of San Francisco Bay and Golden Gate Bridge.
Outside the museum building they have displays of a whale and DNA (Deoxyribonucleic Acid). The kids loved it!
Since the Lawrence Hall Science Museum is on a mountainside it offers great views of Berkeley, Oakland, San Francisco and the bay.
