Introduction
Who I am
Today we will be
Talking about the Invention of the Light Bulb
Seeing our own bulb come on
Talking about Innovation vs. Invention
Learning a little about Energy and Electricity
I'll be asking YOU a lot of questions
I'll be answering your questions too

Sir Humphrey Davies
DemonstratedIncandescence of aPlatinum Filament in
open air in 1802 Used the most
powerful battery thenin existence
Further experimentslead to moreknowledge of
electricity

So Why Edison?
Others Came First
At least 22 people arerecognized by
historians as havingdeveloped bulbs
Edison didn't workalone either (don'tforget the Muckers)

Invention vs. Innovation
Invention
The first occurrenceof a new idea
Not all Inventions arepractical, useful, orneeded
Innovation
The first occurrenceof taking an idea and
making it a workingreality
Put another way:Solving a problem ina useful and effectiveway
