Wes, Julia, Romarion, Jalen Design: Explanation: A: I blow the dominoes and that makes the ball roll (Wind energy to kinetic) B: The ball rolls down the hill (kinetic to potential) C: The ball hits the car with the candle on it (potential to kinetic) D: The car rolls under the string and stops (kinetic to potential) E: The flame burns the string (potential to thermal) F: The car is let go (thermal to kinetic) G: The cart rolls down the track (kinetic to chemical potential) H: The scissors puncture the can (chemical potential to kinetic) Video:

Crystal, Sunita, Rey Design: Explanation: A: We released the car with our hand down the ramp. (potential to kinetic) B: The car hit the dominoes. (potential to kinetic) C: The dominoes hit the bouncy ball. (potential to kinetic) D: The bouncy ball rolled down the ramp to hit the hot wheel. (potential to kinetic) E: The hot wheel rolled down the ramp and hit the metal ball. (potential to kinetic) F: The metal ball went down the ramp and hit the flashlight. (potential to kinetic) G: The flashlight slid and knocked the can off the desk. (potential to kinetic) H: The soda went through the funnel into the cup. (potential to kinetic)

Design: Explanation: A. We rolled the ball (potential to kinetic) B. Weight is moved by the ball (potential to kinetic) C. Ruler is pulled off ramp by the weight (potential to kinetic) D. Ball #2 rolls down ramp (potential to kinetic) E. Dominoes fall (potential to kinetic) F. Car moves (potential to kinetic) G. Weight #2 swings (potential to kinetic) H. Ball #3 rolls down mini ramp. (potential to kinetic) I. Can fall and spills soda into bowl (potential to kinetic)

Design Explanation A: Blew dominoes to make them fall over (wind to potential to kinetic) B: Tennis ball hit weight to that fall off the table (potential to kinetic) C: Toothpick came from under the toy car then toy car went forward (potential to kinetic) D:Candle burned string (thermal to potential) E: String lets go (potential to kinetic) F: Car stays still (kinetic to potential) G: Car goes down ramp (potential to kinetic) H:Can spilling soda (potential to kinetic)

Design Explanation A- Turn on the fan (electrical to wind energy) B- Wind knocks over Styrofoam (wind to potential) C- Styrofoam knocks over dominoes (potential to kinetic) D- Dominoes hit the car (kinetic to mechanical) E- Car hits empty plastic bottle (mechanical to potential) F- Bottle hits the ball (potential to kinetic) G- Ball rolls down ramp (potential to kinetic) H- Ball hits 3 pound weight (kinetic to potential) I-Weight swings and the force when it falls pops open the coke can ( can has a string attached to can, the string is also attached to the weight) ( potential to kinetic) J- Coke pours into funnel (potential to kinetic) K-From the funnel the liquid pours into two metal tubes straight into a plastic cup (potential to kinetic)

Design Explanation A- The candle burns the string that releases the heavy metal ball B- The heavy metal ball hits the dominoes that hit another heavy metal ball C- The heavy metal ball hits a block of wood D- The block of wood hits the car with scissors attached to it E- The scissors cut the fishing line F- The fishing line releases the hammer G- The hammer knocks over the coke H- The coke flows down the the funnel and into the cup Video
