The interactive California Science Center, now in its second phase of development, grows larger every day.  Creative World lets you explore man’s inventions and technologies; you can build a structure that will withstand an earthquake, play virtual soccer or take part in a digital jam session.  The World of Life investigates how living things grow and thrive; you’ll watch baby chicks being hatched or examine human development from a single cell to a fetus.  Take a seat for everyone’s favorite attraction, BodyWorks, where an animated character, Walt, educates you on homeostasis via his buddy Tess, a 50-foot body simulator.  You can also ride a high-wire bicycle and strap up for a cave climb, or just tinker with wind tunnels and solar slot cars.  Tours that go inside aircraft are available at selected times.  Don’t come on weekday mornings, as school field trips make for too much of a crush.  An IMAX and IMAX 3D theater adjacent to the main building offers seven-story-high thrills throughout the day.  The California Science Center is located in Exposition Park, also home to the Natural History Museum, where you can venture next if you want a jam-packed day.  Don’t miss relaxing at the Rose Garden and peeking into the Coliseum sports stadium while you’re there.
