7. 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.

8. 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. _________________________________ Mr. Reiner October 8, 2007

9. 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

10. We discovered that:

11. There are certain materials that create better paths for electricity. Good Conductors tin foil steel Poor Conductors Cardboard Craft Sticks

12. 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.

13. Every cell added to the circuit adds more power to the bulb, which results in a brighter light.

14. The need for a continuous circuit to make the bulb light

15. Batteries need to face the same direction?

16. The lamps in a series circuit are all the same brightness

17. More bulbs in a series circuit means dimmer lamps

18. The same number of cells and bulbs in a series circuit means that each bulb is at normal brightness

19. One cell with two bulbs connected in parallel has the same brightness

20. Other Ideas We Want To Investigate
