Conservation of Energy and the Increase in Disorder (9-12) * The total energy of the universe is constant. * All energy can be considered to be either kinetic energy (the energy of motion) or potential energy (energy of position) or energy contained by a field (such as electromagnetic waves). * Heat consists of random motion and vibration of atoms, molecules, and ions. The higher the temperature, the greater the motion. * Everything tends to become less organized and less orderly over time. (NSES, 1996)

The name of this "learning tool" is Pendulum Experiment and has been developed by Fu-Kwun Hwong. You can perform classic pendulum experiments with your students. A period-initial angle plot is generated automatically, just click/drag the mouse and wait. Try and play with it to find out more features. If the initial set up looks difficult, click on the "simplify version link". |

The name of this "learning tool" is called Masses and Springs. A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring. This tool is brought to us by The PhET Project and made possible by the Kavli Operating Institute. |

Students love skateboards! Now they can design their own and see how well it works. The name of this learning tool is called Skate Park and comes to us from the great web site Phet. You need Java and then just click RUN NOW in the lower right to get started. Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space! |

The name of this "learning tool" is called Heat Transfer between Metal and Water. First choose the metal you wish to test, then the mass and temperature of the metal. Then place the metal in water and watch what happens to your graph! This simple and elegant demonstration is brought to us by the Department of Chemistry at Iowa State University. |

The name of this spectacular "learning tool" is Charges & Fields. Move point charges around on the playing field and then view the electric field, voltages, equipotential lines, and more. It's colorful, it's dynamic, it's free. This tool is brought to us by The PhET Project and made possible by the Kavli Operating Institute. |
