Can u get there by bus from Brooklyn NY and how much for children under 12years Old?

Not sure about the bus ride. Lightrail stops at liberty park (you can walk to the science center from the stop) and you can get on the lightrail if you come to Jersey by PATH train. $17.75 for kids under 13yr

You would have to take a bus from Brooklyn to Staten Island, and then take a bus from Staten Island to Bayonne and then take the light rail from Bayonne to Liberty Science Center. Admission starts around $20 and goes up

It's around 18$ fir kids. I don't think u have a bus to get there i can take the light rail

I don't think there's buses from Brooklyn to Liberty Science Center. However, children from 2 to 12 years old will cost you $18.75.
