Motion: Introduction Motion is one of the key topics in physics. Everything in the universe moves. It might only be a small amount of movement and very very slow, but movement does happen. Don't forget that even if you appear to be standing still, the Earth is moving around the Sun, and the Sun is moving around our galaxy. The movement never stops. Motion is one part of what physicists call mechanics. Evolution of the Universe - GigaPan Time Machine Jump to: From GigaPan Time Machine Direct Cosmological Simulations of the Growth of Black Holes and Galaxies This timelapse shows the distribution of matter in a simulated universe on large scales. Galileo Drops the Ball - Virtual Experiment In around 1590 Galileo Galilei (1564-1642) climbed up the Leaning Tower of Pisa and dropped some balls to the ground. Two balls of different masses, but of similar shape and density that were released together hit the ground at the same time. Until then it was commonly believed that heavy things fall faster than light things. Many people still believe this, and casual observation of everyday phenomena often does tend to confirm this view. If you drop a brick and a feather at the same time the brick will probably hit the ground first.
HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. Acceleration - Physics for Kids! Acceleration is a way to measure how fast something is speeding up. Suppose you are riding your bike. You start out going very slowly, hardly pedaling at all. Now you begin to pedal as hard as you can, to speed up - you are accelerating.

Animal Life Cycles (FREE Learning Material) We are still continuing our vertebrate study and at this point we explored the life cycle of each group. The aim of this study is to compare the life cycle of each group, to differentiate their development and identify their similarities as well. Prior to this, I introduced the Animal Kingdom and the Vertebrate group. To start off, we have The Life Cycle of a Frog for amphibians. Printable materials used here are my Animal Kingdom file, Vertebrate Sorting Cards and the Animal Life Cycles FREE printable.
Science Xplained Science Xplained is a collection of video podcasts that tell the stories of the science behind everyday topics. Dr. Ainissa G. Ramirez, self-proclaimed science evangelist and associate professor of mechanical engineering and materials science at Yale University, is the dynamic host of the series. Filter Resources by Grade: Top 10 Most Dangerous Plants in the World 1. Most likely to eat a rat Giant Pitcher Plant: Nepenthes attenboroughii Discovered more than 5000 feet above sea level on Mount Victoria in the Philippines, the giant, carnivorous pitcher plant secretes a nectar-like substance to lure unsuspecting prey into a pool of enzymes and acid. A series of sticky, downward ribs makes it nearly impossible for trapped prey to escape.
What causes lift? Yesterday, I wrote about one of my favorite kinds of clouds: Kelvin-Helmholtz clouds, also called fluctus clouds. You can call them wave clouds, because that’s what they look like: Waves breaking over a beach. I also embedded a video from Sixty Symbols explaining them, but during that explanation the scientist, Mike Merrifield, made a bit of a flub: He said that with an airplane wing, lift is generated because air is moving faster over the top of the wing than the bottom.
Researchers explain why bicycles balance themselves Ruina Lab/Provided An experimental bicycle designed to eliminate the gyroscopic effect of spinning wheels and the "trail" of the front wheel is still stable on its own, disproving conventional theory. The 1949 movie "Jour de Fete" shows a postman frantically chasing his bicycle, which rides away on its own. News - NASA Space Telescopes Provide a 3D Journey Through the Orion Nebula Astronomers and visualization specialists from NASA’s Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region. Viewers experience this nearby stellar nursery “close up and personally” as the new digital visualization ferries them among newborn stars, glowing clouds heated by intense radiation, and tadpole-shaped gaseous envelopes surrounding protoplanetary disks. Using actual scientific imagery and other data, combined with Hollywood techniques, a team at the Space Telescope Science Institute in Baltimore, Maryland, and the Caltech/IPAC in Pasadena, California, has created the best and most detailed multi-wavelength visualization yet of this photogenic nebula. The fly-through enables people to experience and learn about the universe in an exciting new way.
