__RUBE GOLDBERG__ I think we should win because we had a very cool wow factor with mentos and diet coke. Our whole project was kid friendly, we had no chokeable parts or hazard like materials.Our design was unique becasue we started it from 2 different sides and they ended up in the same ending place.

general energy = kinetic and potential energy. motion / kinetic still / potential kinetic energy depends on it's mass and velocity. kinetic energy =mass x velocity squared over 2. velocity has more of a affect then mass does. work = force times distance.

Vocab

mechanical energy- Kinetic or potential energy associated with the motion or position of an object Thermal energy-Total energy of the particles in an object (heat) Chemical energy-when to chemicals mix to create and make something happen Electrical energy- wires and complex object that can coinduct electricity Electromagnetic energy-Any type of light form is considered electromagnecit Nuclear energy-Stored in the core of an atom

Zach-balls Halle-tubing,duct tape,tinker toys/connectors PLAN Ball rolls down something hitsferris wheel spins then knocks down dominoes and dominoes increase in size then they hit The coke and mentoes fall in some how.

HALLE'S FLASHLIGHT PARAGRAPH

A flash light works when you have a closed circuit. To turn the flashlight off you have to have something that connects in between but it has to be able to open the circuit. When the person turns on and off the switch that takes MECHANICAL energy. Mechanical energy is both KINETIC and POTENTIAL. When you move the switch thats kinetic energy. Whe the switch reaches its place and stops thats potential energy. The light when the flashlight is on starts to get hot. The THERMAL energy in a flashlight happens when you have a closed circuit. A flashlight has electrical energy because there are wires on the inside. The wires connect to the baterry sending a charge of energy through all the conductors. When the light shines it is showing ELECTROMAGNETIC energy. Any visible light is electromagnetic. The baterry inside of the flashlighht is CHEMICAL energy. The electrons and neutrons are part of the chemical energy. When the circuit is working the negatives and positives are all chemicals mixing together.

Energy conversions take place throughout a flash light starting with the battery. The battery is chemical energy. From the battery it goes to electricly because the wires connecting to the battery conduct electricity. When the light goes on it gives off thermal energy because of heat. Electromagnetic occurs when the light is visible. To move the switch on and off you have to use mechanical energy. Whe the switch is moving thats called potential. Moving uses energy and stops stores the energy.

CHEMICAL: When 2 or more compounds combine and make a new form MECHANICAL: Moving objects or work in motion. ELECTRICAL: Circuit, moving atoms producing a shock and closed circuit ELECTROMAGNETIC: The energy of light and other froms of radiation THERMAL: a change in temperature adding or taking away heat NUCLEAR:The stored energy that will cause shock waves when the energy is broken ACOUSTIC: Vibrations caused by sound

Chemical-Glow sticks, baking soda and vinegar, mentos and coke/diet coke

Mechanical- Marble rolling, Dominos, fan

Electrical- Speakers, fan, toaster

Electromagnetic,Ipod, magnets, Batteries

thermal- fire, Lights, computer plug

acoustic- Ipod, vibration,

SKATE PARK when the skater was in the middle he had 50/50 when he was at his starting point he had potential energy then he gained momentum and right before he reached his starting point he gained his most kinetic energy. 100 Then when he reached the opposite side he gained his most potentail energy.100
