Homemade Science Lab « The Kitchen Pantry Scientist Homemade science kits are fantastic, inexpensive holiday or birthday gifts. In addition, they’re great places to store loose science items you might already have around the house, like magnets or magnifying glasses. I’ll list how much some of the ingredients/stuff cost me at Target. Kids' Club Skip to main content NASA Kids Club › Text Only Site Let's Go to Mars! Plan.
Introduction to Shark Evolution, Geologic Time and Age Determination Sharks are one of evolution's most enduring success stories. Although they have few hard parts that can survive the insults of geologic time, sharks have left a long and rich fossil record. Some 2,000 to 3,000 species of fossil shark have been described. Lawrence Hall of Science - 24/7 Science How fast does the wind blow? What makes things sticky? Where do insects live and plants grow? What is the best way to clean up the environment? How do humans measure up in the animal kingdom? The Earth and Beyond Welcome to The Earth and Beyond Hello, my name is Tim O'Brien. I'm an astronomer working at The University of Manchester's Jodrell Bank Observatory. As an astronomer my job is to try and understand how the universe works and my main interest is why some stars explode - more about this later! I also get to visit lots of schools and share amazing facts with children and teachers about the Sun, Earth and Moon, the stars and planets, and the Universe as we know it! Now, in the Children’s University, I can share the excitement with you.
The History of Sound Cards and Computer Game Music Jul 13, 2012 All modern computers have the ability to play high-quality digital sound, thanks to the presence of a dedicated sound card or an audio chip on the motherboard. Today’s computers produce lifelike, realistic audio, enabling us to listen to digital music collections, watch online videos and play action-packed games. However, the audio capabilities of today’s computers are the culmination of decades of development, and it took a significant contribution from the computer game industry to get us here. Without that contribution, anyone who isn’t a professional musician might still be listening to little more than beeps on his or her computer today.
The Energy Story Energy is one of the most fundamental parts of our universe. We use energy to do work. Energy lights our cities. Kids Science Experiments - Gravity - Spinning Bucket of water 1. Fill the bucket three quarters of the way with water. 2. 21 Terrifying Deep Ocean Creatures Scary Seas: 21 Terrifying Deep Ocean Creatures Article by Marc, filed under Destinations & Sights in the Travel category. The last true frontier on Earth is deep in the ocean. Any expedition to the dark depths is incredibly expensive, yet invariably comes back with a host of newly discovered species that are about as alien to land dwellers as it’s possible to get on this planet.

40 Pictures of Airplanes Breaking the Sound Barrier Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects travelling in dry air of a temperature of 20 °C (68 °F) this speed is approximately 343 m/s, 1,125 ft/s, 768 mph or 1,235 km/h. A sonic boom is the sound associated with the shock waves created by an object traveling through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding much like an explosion. So that means that the sound source (in this case an airplane), will pass by a stationary observer (like yourself) before they actually hear the sound it creates.
Secret Worlds: The Universe Within - Interactive Java Tutorial Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode.

Gödel and the limits of logic June 2006 The man in the photograph on the right looks formal, reserved and somewhat undernourished. His face and his writings are unfamiliar to most, except for a few philosophers and mathematical logicians. He was Kurt Gödel, celebrated for his incompleteness theorems, the implications of which are far-reaching for the foundations of mathematics and computer science. The story of his life and work is that of a persistent quest for rationality in all things, pursued against a background of recurrent mental instability. Gödel proved that the mathematical methods in place since the time of Euclid (around 300 BC) were inadequate for discovering all that is true about the natural numbers.
