Group 1 Nathan, Bryan, Dusty, Hannah

**Description**
A: we aired up the balloon(mechanical energy). B: the balloon knocks the track with the car on it off balance(kinetic energy). C: the car rolls into the ball(kinetic energy). D: the ball hits the dominos(kinetic energy). E: the dominos hits the last domino and knock it into the balance(kinetic energy). F: the balance gets knocked off balance rising the candle up(kinetic energy). G: the candle burns the rope above it(chemical energy). H: the rope burns and cuts off the connection to the weight(chemical energy). I: the lighter wieght falls onto the balloon and pops it(kinetic energy).

Video:sorry guys, the camera man messed up your video. This is the best we got! :0(

Group 2

Hannah, Tyler, Emma, Ana

Diagram:

Insert description here: 1: The marble is sitting on top of a wooden stick, and is pushed down. (Potential à Kinetic) 2: The marble rolls through into the tube. (Potential à Kinetic) 3: The marble rolls down the ramp. (Potential à Kinetic) 4: The marble hits the mouse, and it triggers. (Potential à Kinetic à Mechanical) 5: The mouse trap pulls the string on the hammer, pulling it to the balloon. (Potential à Kinetic à Mechanical) 6: The hammer pops the balloon. (Potential à Kinetic)

Insert description here: 1.The ball rolls down the ramp. (potential to kinetic) 2.The ball pushes down on the ramp causing it to enter the tube. (potential to kinetic) 3.The ball hits the pointy finger which is hanging on the newtons cradel. (potenital to kinetic) 4.The pointy finger pushes the switch on the compressor. (kinetic to mechanical) 5.The ballon attached to the compressor airs up. (potential to kinetic) 6.The needle pops the ballon that is already blown up. (potential to Kinetic)

** Rube Goldburg Machine-  ** Popping a balloon This is potential energy changing to gravitational kinetic energy. ||
 * Energy Changes as Labeled   ||    Description of Energy Changes    ||
 * A   ||  The lighter is lit and burns the string. This is a transfer of chemical energy.  ||
 * B   ||  When the string is burnt, it causes the string to fall from the pulley, releasing the end of the ramp, creating a ramp for the marble to roll down.
 * C   ||  The marble runs into the car, pushing the car forward. This is potential energy changing to gravitational kinetic energy.  ||
 * D   ||  The car rolls forward and hits the next car, causing it to roll forward. This is another energy change from potential to kinetic energy.  ||
 * E   ||  The second car hits the dominoes, which fall of the table and trigger the mouse trap car. This is potential energy switching to gravitational kinetic energy again.  ||
 * F   ||  The mouse trap car pulls the domino out from under the book. The mouse trap car is elastic potential energy going to kinetic energy.  ||
 * G   ||  The book falls onto the clamp. This is again, potential to kinetic energy.  ||
 * H   ||  The clamp opens, allowing the string to fall out. This is a potential to kinetic energy change.  ||
 * I   ||  The book falls on the balloon, which is sitting on tacks, causing the balloon to pop. The balloon has potential energy until it pops with kinetic energy.  ||
