Virtual Lessons

  • All About Temperature: Celsius vs. Fahrenheit
  • How hot should our solar ovens get to cook and egg?
  • How long should it take?

Daniel Gabriel Fahrenheit

  • German scientist named Gabriel Fahrenheit
  • Had an idea (1714)
  • Mercury expands and contracts a lot with temperature
  • Mercury doesn't evaporate
  • Set up his own scale for measuring temperature
  • 32 degrees freezing point, 212 degrees boiling point
  • Scale based on the 360 degrees in a circle: Water boils at 212 degrees so - 180 degrees equals it's freezing point. Strange, but true!

Anders Celsius

  • Came up with Celsius Scale in 1742
  • Centigrade scale: 0 degrees C is freezing and 100 degrees C is boiling
  • Scale that scientists use: Cent is Latin for 100 and Grade is Latin for degree or step.
