The Liberty Science Center

Set in Liberty State Park which overlooks the Statue of Liberty and Ellis Island, this museum combines whiz-bang science, a small aquarium, great traveling exhibits and the largest IMAX theater in the U.S.

The outside shape of the museum sports its distinctive hump which can be seen from the Jersey Turnpike, but a whole new wing has been added. The square footage has expanded with scads more space inside, much of it devoted to lecture rooms. The large central atrium has shrunk in size and escalators have disappeared, but elevators and stairs are plentiful. The administrators are obviously expecting lots and lots of classes, because there are several staging areas where troops of kids can gather around a speaker. And there are plenty of science "mentors" to help the patrons out.

The first floor consists of a deployment area for the school kids to assemble, the ticket counter and a large gift shop filled with stuffed animals, books and science-related projects. On the left, a major permanent exhibit that is dedicated to skyscrapers dominates the floor. Here you can look at girders (you are even allowed to walk on one, under supervision of course, and using a harness) and learn everything you might ever want to know about the evolution of sky-high construction. There are even mock-ups of well-known New York buildings and a working elevator.

On the second floor, you'll find a room dedicated to toddlers and small kids. What a great idea! Anyone from one to five can play here while their older siblings view the technical intricacies of moving lights or communications. Along with their adult caregivers, little tykes can explore what is under a city sidewalk, compose their own music on ringing rocks or construct simple structures with Legos.

My favorite exhibit in the Center is called Eat or Be Eaten. Since I do not plan any expeditions to the Amazon River in the near future it's nice to be able to examine some of the denizens of that rain forest (plus other far-flung outposts) to see how creatures evolved tools and strategies to catch their prey while avoiding being caught themselves. There's the poison dart frog, the coral snake, and a bevy of insects that either camouflage themselves to look like the forest floor or create cunning traps for the unwary. It's like watching the Discovery Channel up close and personal.

Another exhibit geared to the whole family is called Our Hudson Home.
When the first European explorers entered the mouth of the Hudson River, they thought it was so vast that it might lead to China. This exhibit is actually a small aquarium with several large tanks of fish native to the region swimming lazily around. It has been much expanded from the small tanks that once dominated the top floor of the center and the accompanying information plaques are superb. Unlike colorful tropical fish, Hudson area types are big and ugly but make a fascinating viewing nevertheless.

How long will fossil fuels last us and what are the alternatives? That's the basis of an important exhibit concerned with the major sources of Earth's energy. Visitors are urged to experiment with alternatives sources to see what tomorrow may offer. And the Communications exhibit covers everything from the handprints on cave walls to the digital tools that link us today with plenty of flashing digital lights that dance along the walls to perk up the senses.

Among the public favorites in the museum is the rock-climbing wall which you actually climb sideways rather than up and down. It is studded with fossils (or at least facsimiles of fossils) so that it's a learning exercise as well as a physical one. A quick lunch is available at the redesigned "Café Skylines" which features the usual array of sandwiches and salads.

The Center hosts two theaters. One is the IMAX Theater the largest in the country. Here you can sit in a tiered semi-circle and immerse yourself in the giant images that surround you from the 88-foot domed screen. The center shows three different films per day and you can choose the one you prefer beforehand. In fact it's best to go to the Internet (www.lsc.org) and read the write-ups of each film before you visit. You can reserve your tickets beforehand if you plan to go during a popular week (such as a holiday or school closing time). Otherwise pre-ticketing is not necessary but it's a good idea to choose which film you think might interest the members of the family. Children under two are not allowed in the IMAX Theater and since the film experience is so overwhelming, it is suggested that children should be at least six in order to attend.

The other attraction is the 3D theater. You can see close-ups of bugs or whatever else the film is featuring in all their three-dimensional glory. Of course it requires the special 3D glasses that are handed out when the film starts. Here again, very young children may not like the experience, but school kids love those 3D plastic spectacles and the in-your-face feel of it all. There is an extra charge for both theaters, but you can buy a combination ticket for the exhibits and the theater or the IMAX or all three at once.

Last but not least is the huge space allotted for traveling exhibits. The one I saw took at least a half an hour to walk through. Traveling exhibits come from all over the country and change every few months.

The Liberty Science Center is located at 222 Jersey City Blvd. Take Exit 14B on the Jersey Turnpike to Liberty State Park and turn left at the sign. Parking at the adjacent lot is $7.00.
Admission prices vary. There is museum only, combination tickets, and reduced prices for children and seniors.
