Nitrogen: Hi my name is Nitrogen and I am a gas. I am found in the Earth's atmosphere and i make up about 78% of the air. I am sometimes used to preseve historical documents such as the Declaration of Independence. I sometimes like to save lives and i am into the airbags in cars. I also can be a little dangerous and be put into dynamite and other explosive equipment.

Krypton: Hola! I am Krypton and I am a noble gas. I only make up about 0.00014 percent of the atmosphere. I was discovered by liquifying air! I am never found in my solid forms and I can be used in lightbulbs. I am shot around using lasers.

Non-renewable Resources: Nuclear- comes from uranium Fossil Fuels~ Natural Gas-low output of carbon dioxide Petroleum-makes synthetic fabric(rayon) Coal-Most coal used for electric power

January 22, 2008 ~Energy is the ability to do work. ~Work is the action that results if a force causes an object to move in the direction of the force. ~Both energy and work are measured in joules (J) ~One joule is a newton meter. ~The two main types of energy are Kinetic and Potential energy. ~Kinetic energy is the energy of motion. ~Potential energy (stored energy) is the energy an object has because of its position and shape. ~The various forms of energy are thermal, chemical, electrical, sound, light and nuclear energy.
