GAMS REVIEW

Evidence:

Cell phones are powered by a battery that produces the electricity used to send or receive a call.

Transformation 1: Sound energy is transformed into

electrical energy by cell phone A.

Transformation 2: Electrical energy is transformed into mechanical energy in the cell towers and base station

Evidence:

Cell phones are powered by a battery that produces the electricity used to send or receive a call.

Transformation 1: Sound energy is transformed into

electromagnetic waves by cell phone A.

Transformation 2: Electromagnetic waves are transformed back into sound energy by cell phone B.

Evidence:

Base stations are powered by a battery that produces the electricity used to receive and forward a call.
