What energy transformations can you see?
00:00:11
Listen, then tell your partner.
00:00:15
In photo A, wind turbines transform the mechanical energy of wind into electrical energy.
00:00:19
In photo B, the chemical energy in food is transformed into mechanical energy
00:00:27
In photo C of an electric guitar, electrical energy is transformed into sound energy
00:00:37
In photo D of a street lamp, electrical energy is transformed into light energy
00:00:48
In photo E of a radiator, chemical energy is transformed into thermal energy.

At the book, and you're going to see it in the file.
00:05:39
It's going to be interesting.
00:05:57
All right.
