3. The next several slides are a sample of student work as well as sample activity sheets.

4. CFL’s + use 75% less energy + last ten times longer + create less heat - contains mercury - takes longer to warm up Parts of a CFL 5/11/09 [image] http://www.energystar.gov/ind ex.cfm?c=cfls.pr_cfls_about Student- Matt Lang

5. Incandescent bulbs + brighter + used for heating + no mercury - use more energy - don’t last as long Light bulb structure 5/13/2009 [image] http://home.howstuffworks.com/light-bulb1.htm Student – Matt Lang

6. INCANDESCENT Heats tungsten filament to produce light Cheaper per bulb More expensive to use More energy required to run Efficiency as low as 10% Same technology as the year 1871 Student- Allen Bolden
