Explanation:

A. We wound up the walking toy.(mechanical) B. The walking toy then walked in to the scissors(mechanical to kinetic) C. The scissors turned(potential to kinetic) D. The wound up car then began to role pulling the string(mechanical to kinetic) E. The ball then rolled down the ramp(potential to kinetic) F. The dominoes were then hit by the ball making them fall(potential to kinetic) G. The car was hit by the dominoes which rolled under the balloon with the candle on it(potential to kinetic) H The candle then transferred its heat to the balloon popping it(thermal)

=Kyra, Ali, Madi= Design Explanation

Explanation A) Ball starts in potential energy B) Ball hits cart that starts in potential energy but then once the ball hits the cart it turns to kinetic energy C) Cart rolls down the ramp and hits the blow dryer, turns the blow dryer on which is electrical energy D) The ball in front of the blow dryer is in potential energy E) Blow dryer blows ball which is kinetic energy F) Ball rolls down the ramp which is kinetic energy G) Car starts in potential energy F) Ball hits car which turns into kinetic energy I) Call hits the balloon with a tack on the front or it and pops the balloon which is kinetic energy

Tabitha, Dylan, and Adam Design: Explanation: A) The block tied to the string swung down around the ring stand and hits the domino B) The dominoes transfer potential to kinetic from one to another and the last domino hits the mouse trap C) The mouse trap is triggered and it undoes the bow releasing the Newton ball D) Potential and kinetic energy is transferred throughout the newtons balls and the last ball hits the first domino. E) The dominoes transfer potential to kinetic energy from one to another and the last domino hits a wooden ball F) The wooden ball rolls and hits another wooden ball, transferring the energy between the balls G) The second wooden ball rolls down the slope and hits the toy car once again transferring the energy H) The toy car with a tack on the end rolls forward hitting the balloon I) The balloon pops!

Design: Explanation: A. The weight is held up, containing potential energy. B. After, the weight is released, the weight falls, and gains kinetic energy. C. When the weight falls it pulls a string causing the golf ball to move releasing the balls. The balls have potential energy before being released. D. When the balls have been released, they roll down a ramp. The balls now have kinetic energy. E. Before the balls hit the soccer ball, it has potential energy. The balls hit the soccer ball and cause the soccer ball to move. F. When the soccer ball moves, it bumps into the science books causing them to fall over. The books have potential energy, and then it is converted into kinetic energy. G. The books fall over and kit the see - saw, causing the book to weigh down the see - saw. The see - saw contains mechanical energy. H. When the see - saw moves up, it hits the inside of the cardboard box, causing the book to fall which is kinetic energy. I. The first book hits the second one which has thumbtacks on it. J. the book with thumb tacks fall on the balloon causing it to pop.

Design: Explanation: A. The ball is held at the top of the ramp, containing potential energy. The ball is released, and it rolls down the ramp, gaining kinetic energy. B. When the ball rolls down the ramp, it hits the Newton balls which have potential energy. The Newton balls start moving, which is kinetic energy. C. Then they hit the dominoes, which have potential energy, making them fall into each other, which is kinetic energy. D. When the dominoes are falling they set off the mouse trap, which has potential energy. Then the mouse trap goes off and has kinetic energy. E. The mouse trap has a ball tied to a string on it, which is potential. When it goes off it pulls the ball out of the way, which is kinetic, letting the pull-back car go, which transforms from potential to kinetic energy. F. The pull-back car goes down the track, knocking the metal ball tied to the switch on the fan off the table, which has potential, and then changes to kinetic. G. The metal ball falls off the table, turning the fan on, which has potential that turns to kinetic. H. The fan turns on which pushes the sail-car toward the candle, which has potential, then turns to kinetic. I. The sail-car runs into the candle, which has potential and thermal energy. J. The candle gets pushed toward the balloon, which is kinetic. Then the heat makes the balloon POP! :)

Adam, Jacob & Tyler Design: Explanation: A. The ball is attached to the ruler as a pendulum and is let go to hit the cup gaining kinetic energy. B. The cup is knocked over to release the marble inside to have kinetic energy. C. The marble rolls down the ramp gaining potential energy. D. The marble hits the second pendulum gaining potential energy. E. The car is released and roles down the hill gaining kinetic. F. The car hits the dominoes changing from potential to kinetic. G. The dominoes hits the ball and rolls down the ramp gaining kinetic. H. The ball rolls into the wood plank and "POP!" Loosing potential and gaining kinetic.

Schyler, Blake, John

Design:

Explanation: A. The hammer was released, and swung like a pendulum-PE to KE B. The hammer hit the wood ball, starting the wood ball's movement-PE to KE C. The wood ball hit the newton balls, starting their movements-PE to KE D. The newton balls hit the dominoes, starting the domino effect-PE to KE E. The domino hits the weight, knocking it into the cup-PE to KE F. The weight pulls the cup down, pulling the string on the pulley-PE to ME G. The string pulls the ruler up, moving the car down the track-PE to KE H. The car rolls down the track, and falls, needle first, into the balloon, popping it-KE to PE Video:

Brett, Dominique, Marquisha

Design: Explanation: A. The Newton balls were released. PE to KE B. The Newton balls hit the second ball and it rolled down the ramp. PE to KE C. The second ball hit the third ball and it rolled down the ramp into the car. PE to KE D. The car hit the second car PE to KE E. The second car hit the dominoes and they fell over. PE to KE F. The dominoes pushed a pointer. PE to KE G. The car that was attached to the pointer rolled under the balloon PE to KE H. The candle on top of the car heated up and popped the balloon. KE to TE Video:
