 * Types of Energy**
 * Mechanical Energy-** the energy associated with the motion or position of an object. Can occur as kinetic or potential energy, examples are: school bus, frog jumping, and sounds.


 * Thermal Energy-** the total energy of the particles in an object. When thermal energy increases its particles move faster making it feel warm. Examples are: melting ice cream.


 * Chemical Energy-** potential energy stored in chemical bonds that hold chemical compounds together. It is stored in the food you eat and in a match that is used to light a candle. Chocolate, wood and wax store chemical energy.


 * Electrical Energy-** moving electric charges produce electricity or electrical energy. You rely on electrical energy from batteries or power lines to run electrical devices such as radios lights and computers. Examples are: when you recieve a shock from a metal doorknob.


 * Electromagnetic Energy-** Electromagnetic Energy travels in waves, the light you see each day is a form of electromagnetic energy. These waves have some electeical properties and some magnetic properties.In addition to visible light, ultra violet radiation, microwaves, and infrared radiation are all examples of electromagnetic energy.


 * Nuclear Energy-** a type of potential energy that is stored in the core, or nucleus, of an atom. One type of nuclear energy is nuclear reaction and happens when a nucleus splits. Another kind is when nuclei fuse or join together. Powerplants use nuclear energy. These reactions release tremendous amounts of energy.

We are going to use mechanical energy by a ball sitting at the top of a ramp. Then we will release it and it will hit another object. That is meechanical energy because it is associated with the position of the ball.

We are going to use thermal energy by having a heater next to a pyramid of ice and a ball at the top and when the ice melts, the ball will roll down and hit another object. This is thermal energy because the ice is heating up to melt.

We are going to use chemical energy by

We are going to use electrical energy by having a fan that has a battery push a light ball and make it go to one side so it goes where we want it to. This is electrical energy because the battery is powering the fan. The energy in a flashlight comes from the battery, then through the wires, then to the light bulb, the switch stops the wires from touching. We learned from the ramp experiment that friction can cause noises and slows down the ball by using energy.



Our experment did not work this time. It worked many times before and was supposed to work this time by the ping pong ball rolling down and giving a sticker out to the child but it failed. We had gravitational potential energy in the baseball sitting at the top rolling down the ramp. After it started rolling down the ramp, It became kinetic. The card opening was mechanical, chemical for the battery, electic for the wires, and acoustic for the sound the card made after it was open. The baseball hit the tennis ball that knocked several dominos over, this was all mechanical. The stack of dominos was supposed to fall over and hit the orange ping pong ball down the cardboard ramp, which was graviational potential to kinetic. It would then hit a stamp out into the bowl shaped cardboard for the kid to take. However the stack of dominos did not fall.
