NASA's Neurolab mission conducts brain research to study behavioral and nervous system changes in space. Thanks to NeurOn (Neurolab Online), students around the world can join NASA personnel to get a close-up look at this historic mission. Shuttle out to http://quest.arc.nasa.gov to read the journals of crew members, browse through the photo galleries or watch the NeurOn team experiments. You may want to check out the habitat designs, or simply stroll around the Kennedy Space Center. Kids will especially love NeurOn ExPress, the magazine produced for and by kids, and the Student Gallery, which includes great poems, artwork and writing related to space. Neurolab Online also has video broadcasts of the mission, chats with the crew, and a forum to ask your toughest questions. Neurolab is the ultimate exploration of space and mind!

Interact with the sights and sounds of science at Explore Science, a Shockwave-induced laboratory where the laws of science meet real life. Follow the prism's light to www.explorelearning.com and enter into a world of science gone mad. Mouse genetics, the physics of golf and the forces on an airplane wing are just some of the far-out theories you'll observe. There's also an orbit simulator for the space set, a terminal velocity freefall lab, and a see-saw torque experiment. Explore Science also has some cool games to play, like Black Hole and the Snowflake Designer. From 2D collisions to harmonic motion, this is no ordinary science site. Just remember to bring your lab coat!

How come your parents can remember embarrassing things you said ten years ago when you can't remember what you ate for dinner last night? Memory can play tricks on you, but if you remember to visit this cool site, you'll learn all about how memory works and how to strengthen your own memory muscles. Get this in your brain: www.exploratorium.edu/memory Check out the cool interactive memory games and find out why we remember people best by their hair. How far back in your life can you remember?

What rumbles and roars and spits fire 24 hours a day? It's no monster; it's the planet Earth! Sure, there's lots of beauty in nature, but deep underground, our planet holds some horrifying secrets. Savage Earth lets you in on the real science behind some of the Earth's most frightening phenomena: earthquakes, volcanoes, and tsunamis. Ground yourself at www.pbs.org/wnet/savageearth for the hot way to learn the truth about lava, tidal waves and plate tectonics. The earth-shaking animation helps you see the X-ray view of disasters, and you can "ask the experts" all your burning questions. Don't let this site scare you, though. It's all about helping us better understand the way our planet works. It's one site you'll definitely want to get swept up in!

Imagine teeing up a golf ball in Los Angeles and aiming for a 4-inch moving hole in Houston. This is the challenge that NASA faced in the summer of 1997 while navigating the Pathfinder mission to Mars. Rocket to www.nationalgeographic.com/
features/98/mars and strap yourself in for a wild ride through outer space. This virtual reality tour lets you gaze across the Martian landscape or watch Pathfinder's fiery plunge and beachball landing into the red planet. Not spacesick yet? Then hop in for a virtual ride on the Sojourner, the first-ever interplanetary rover. Then wrap up your visit by sending your friends a "Greeting from Mars" postcard.
