1. Where Does Light Come From?
Lesson 2

2. 8 parts of a flashlight

3. Evidence that Light is a form of energy
Monarch
Caterpillar
Monarch
Chrysalis
Monarch
Butterfly
In both cases all three examples are the same thing, just in a different form.
Chemical Energy
(Batteries)
Kinetic Energy
(Motor)
Light
Energy (Filament)

4. Big Idea:
Yes light comes from flashlights, the sun, LED’s, glow sticks, lightning bugs, etc. but. . .
Light is made of a result of energy transformations.
For example, in the light bulb of the flashlight, electrical energy (in the wires) was transformed into light energy (in the filament).
