Watersheds Box Forms of Energy: Motion, Heat, Light, Sound What forms of energy is Raul using to move his LEGO car? When he was a teenager in Romania, Raul Oaida became obsessed with building things: a jet-engine bike, a tiny spaceship, a LEGO car that runs on air. Why? Well, why not? The JASON Project Coaster Creator is an interactive game that explores the science behind roller coasters. Use your knowledge of potential energy and kinetic energy to design your own coaster. Rapid energy transfer is the key to roller coaster thrills but be careful – too much kinetic energy and you’ll crash, too little and you’ll stall. Play this game and find out if your coaster will be a smash or a snore! Important Words in this Resource:
Internal Combustion" The principle behind any reciprocating internal combustion engine: If you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. You can use that energy to propel a potato 500 feet. In this case, the energy is translated into potato motion. You can also use it for more interesting purposes.
Cell Division Cell Division Functions in Reproduction, Growth, and Repair Cell division involves the distribution of identical genetic material, DNA, to two daughters cells. What is most remarkable is the fidelity with which the DNA is passed along, without dilution or error, from one generation to the next. Core Concepts: All Organisms Consist of Cells and Arise from Preexisting Cells Mitosis is the process by which new cells are generated. Meiosis is the process by which gametes are generated for reproduction. Virtual Earthquake - An Introduction What's an earthquake? Earthquakes occur because of a sudden release of stored energy. This energy has built up over long periods of time as a result of tectonic forces within the earth. Most earthquakes take place along faults in the upper 25 miles of the earth's surface when one side rapidly moves relative to the other side of the fault.
Coaster Welcome to the death defying Funderstanding Roller Coaster! This simulator is designed for people who want to design their own thrilling coaster and educators who want to use a cool activity to simulate the application of physics by using an exciting interactive tool and access to a wonderful reference source. It is your mission to become a roller coaster designer so that you can achieve maximum thrills and chills without crashing or flying off the track (unless that’s how you like your coaster to work!). If you accept this mission you must decide on a number of factors. Alternative fuel vehicle An alternative fuel vehicle is a vehicle that runs on a fuel other than "traditional" petroleum fuels (petrol or diesel); and also refers to any technology of powering an engine that does not involve solely petroleum (e.g. electric car, hybrid electric vehicles, solar powered). Because of a combination of factors, such as environmental concerns, high oil prices and the potential for peak oil, development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world. Hybrid electric vehicles such as the Toyota Prius are not actually alternative fuel vehicles, but through advanced technologies in the electric battery and motor/generator, they make a more efficient use of petroleum fuel. Other research and development efforts in alternative forms of power focus on developing all-electric and fuel cell vehicles, and even the stored energy of compressed air. Single fuel source

Apollo 15 Hammer-Feather Drop 8.3 Mb Quicktime movie of the demonstration At the end of the last Apollo 15 moon walk, Commander David Scott (pictured above) performed a live demonstration for the television cameras. He held out a geologic hammer and a feather and dropped them at the same time. Because they were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer, as Galileo had concluded hundreds of years before - all objects released together fall at the same rate regardless of mass. Mission Controller Joe Allen described the demonstration in the "Apollo 15 Preliminary Science Report": During the final minutes of the third extravehicular activity, a short demonstration experiment was conducted.
Alternative Fuel Vehicles Alternative fuels are derived from resources other than petroleum. Some are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources. Often, they produce less pollution than gasoline or diesel. Classroom Activity: Snack Tectonics Make the model Give each student about a square foot of wax paper and a large dollop of frosting. Instruct students to spread frosting into a layer about half a cm thick. Tell students that the frosting in this model represents the asthenosphere, the viscous layer on which Earth's plates ride. The plates in this model are represented by fruit roll up (oceanic crust which is thin and dense) and graham crackers (continental crust which is thick but less dense).
