Under Pressure!

Today's learning target was...the student will be able to explain the concept of atmospheric pressure.

As a class, we decided on the main ideas...
  • Atmospheric pressure is the weight of air molecules
  • As altitude increases, atmospheric pressure decreases
  • When pressure is low, expect rain or snow; when pressure is high, expect a blue sky; wind blows from highs to lows
  • An isobar is a line connecting points of equal atmospheric pressure
  • A barometers is a tool used to measure atmospheric pressure

Remember, our assessment will take place this Thursday (3rd and 4th hour) or Friday (5th, 7th, and 8th hour)
