__Potential energy__- energy that is stored and has the potential to do work. Objects that can be stretched or compressed have elastic potential energy. Gravitational potential energy is energy that has ot do with the height of an object. We can use potential energy in our project by using rubber bands because rubber band stretch and compress. When we have the ball on top of the ramp it has gravitational potential energy.

__Kinectic energy__- energy of motion. We can use kinectic energy by having an object such as a washer or wheel rolling down a ramp and then bumping into another object causing the second object to move.

__Mechanical energy__- energy that comes from the motion or position of a object. We could use mechanical energy by having an object hit a button on a remote control from a remote contol car or toy causing the car or toy to move.

__Chemical energy__- a potential energy stored in chemical bonds that hold chemical compounds together. For example chemical energy is stored in the food that we eat.

__Electromagnetic energy__- energy that travels in waves. This energy is the light that you see each day. Some examples of electromagnetic energy are ifrared radiation, microwaves, and ultraviolet radiation. We will have a light that turns on.

__Thermal energy__- energy that can produce heat and is caused by the movement of an object's particles. For example an icecube melts when its thermal energy increases. We could use thermal energy in our project by having a heater blow onto an icecube. The the icecube would melt and the water would run onto a seasaw type object.

__Electrical energy__- energy coming from batteries or power lines. Moving electric charges produces electricity. We can use electrical energy by making a circuit.

__Nuclear energy__- potential energy stored in the core of an atom. Nuclear energy is found in nuclear power plants and in the sun


 * __Stuff we could use__-
 * Ball,
 * slide,
 * washers,

 * wires,
 * icecubes,
 * heater,
 * Christmas lights,

Chemical energy- could be demonstrated in a battery that would contain potential energy, a remote control car, and a phone Electrical energy- could be demonstrated through the wires in a circuit runnng from the battery to a light which will have eleectricity running through them when the light is turned on. Electrical energy could also be demonstrated in a electric fan and an ipod. Mechanical energy- could be demonstrated when a ball rolls down a ramp, dominoes fall into eachother, and string pulls a plastic cup up and down. Acoustic energy- could be demonstrated through the sound from dominoes falling into eachother, the ball rolling down the ramp, and a ball rolling into a plastic cup. Thermal energy- could be demonstrated when the chrismas lighs turn on, emmitting heat. Also through a heater and through the mechanical energy that is transferred to thermal energy when the ball rolls down the ramp. Electromagnetic energy- could be demonstrated through christmas lights, a radio, or a flashlight.

4. The energy track was a wooden ramp with a ball rolling up and down it. When the ball was at the top of one side of hte ramp, it had 100% gravitational energy and when the ball was in the middle of the ramp it had 100% kinetic energy because it was moving atg full force. As the ball kept rolling along the ramp it lost its momentum and began to slow down due to the friction between the ball and the ramp. The mechanical energy from the ball was tranferred to heat and acoustic energy causing the ball to eventually stop moving. No energy was lost... it just changed form.

3. Mechanical energy is used when you flick the switch to turn on the flashlight. Electrical energy is used by the circuit within the flashlight. Chemical energy is used by the battery in the flashlight. Electromagnetic energy is used because a light turns on. Thermal energy comes from that light as well.
