Ideas acoustic- the clacking of the dominoes creates sound or acoustic energy mechanical- the ball rolling, the wheel moving, the dominoes falling, and the sticker going up on the teeter totter gravitational potential-the ball sliding down and the dominoes falling into the plate.

potential energy is stored when the string pulls the car back. When the car is released it is converted into kinetic energy.

At the beginning of the chain reaction, we will have a fan that will be plugged in showing an example of electrical energy. Visitor may start chain reaction by turning on the fan, which will blow the marbles off their platform.

Definitions The ability to do work or cause change and is measured in joules-**energy** ** Work ** - the transfer of energy ** Kinetic ** **energy**- the energy of motion Kinetic energy depends on the mass of the object and it’s velocity Bowling ball =more kinetic energy than a golf ball Mass X velocity squared divided by two ** Potential ** **energy**- energy that is stored and held in readiness ( wind up toy, bow and arrow with arrow pulled back ready to be shot) Potential energy depends on height is call gravitational potential energy Force (weight) X distance

Mechanical energy- the energy associated with the motion or position of an object. Can occur as kinetic and potential energy Thermal- the total energy of the particles in an object when the thermal energy of an object increace it’s particles move faster Chemical- Chemical compounds store chemical energy which is potential energy stored in chemical bonds. (stored in a match, chocolate etc) Electrical- moving electric charges that produce electricity. OR electrical energy Electromagnetic- travel in waves in form of the light that we see every day

In our popper experiment, there was 100% of potentil energy when the popper was on the table about to pop and there was the most kinetic energy was when the popper pops and is flying in the air at it's highest point. it was 50/50 when the popper was in between the table and the air

In a flashlight, first there is electrical energy when electrical current flows through a wire connected to the bulb, which is what causes the light to turn on. The light creates both thermal and electromagnetic energy. There is chemical energy in the battery used in the flashlight. Mechanical energy is used to pull the hook which will turn the flashlight on and off.

Explanation: In the video you will see a bouncy ball being pushed down a ramp using a hair dryer. The hairdryer is showing thermal, electical,and mechanical energy. The ball will fall into the paper cup which is attached to the wheel. This causes the wheel to turn and hit the dominoes underneath it.(mechanical energy) The dominos falling will make noise creating acoustic energy. After all the dominos fall, the last one will fall off the end of the table and into a paper bowl, that lifts the opposite side of the 'teeter-totter' showing a sticker.
