Sir Joseph Wilson Swan Award
This certificate certifies that the owner knows how to light a light bulb using everyday objects.
1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he was
the first one to successfully demonstrate his new electric lamps in Newcastle, England.

Thomas Alva Edison Certificate of Electrical Knowledge
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a
carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.
This certificate certifies that the bearer knows how to light a light bulb using everyday objects.

Since this class is so intelligent...1. Connect one D-cell to two bulbs.
2. Connect two D-cells to one bulb.
3. Connect two D-cells to two bulbs.
4. Connect two D-cells to three bulbs. 5. Connect two D-cells to three bulbs.
6. Connect three D-cells to three bulbs.
7. Connect two D-cells to two bulbs but 7A. Connect the batteries the same way 7B. Connect the batteries opposite ways
There are certain materials that create better paths for electricity.
• Good Conductors
•tin foil
steel
• Poor Conductors
•Cardboard
Craft Sticks
When electricity needs to do a job, there needs to be a unbroken road
to work, and an unbroken road back "home"
• Atlanta Motor Speedway
• This is called a circuit.
This is called a circuit.
