===Our Rube Goldberg contraption will start with the guest turning a hand crank that will push a ball down a ramp. The ball will land in a basket that is connected to the arm of a mini-ferris wheel. The weight of the ball will turn the ferris wheel and another arm of the ferris wheel will push a metal cylinder attached to a swing. The metal cylinder will land on a broken circuit and will complete the circuit, causing a bin full of golf balls to open. the golf balls will roll down a ramp and land in another empty bin. The bin will be suspended in the air by a string, the string will be attached to the on-button of a lighter, when the golf balls land in the bin, they will increase the weight, causing the lighter to turn on. Above the lighter, there will be a beaker filled with corn kernels, and above the kernels, there will be an unbalanced plate with a heavy bar taped to the top. When the heat from the lighter pops the kernels, the popcorn will push the plate off. The when the plate falls, the heavy bar will hit a tube, the tube will push two other tubes, one will push the plate back up, the other will push a button and stamp the child's hand.===

Energy- The ability to do work or cause change.

Kinetic Energy- energy of motion.

Potential energy- energy that is stored and held in readiness.

Gravitational potential energy- potential energy that depends on the height of an object.

Elastic potential energy- the energy of compressed or stretched objects.

Mechanical- energy associated with motion and position.

Thermal- the vibration of the particles in an object.

Chemical- potential energy stored in chemical bonds that hold chemical compounds together.

Electrical- the energy of moving electric charges.

Electromagnetic- the energy of light and other forms of radiation.

Nuclear- the potential energy stored in the nucleus of an atom.

Chemical Ideas- use a lighter to pop popcorn.

Electromagnetic Ideas- the lighter gives off light.

Mechanical Ideas- using a hand crank to push the ball.

Acoustic Ideas- using a whip to push something because whips break the sound barrier.

Thermal Ideas- use a lighter to pop popcorn. Electrical Ideas- use a circuit to open a bin. Here is are contraption hope you like it and if we had more time we would have fix a ferris wheel



The energy flow Starts when the chemical energy in the battery transfers into electrical
