Dear
Educator,
 The
change in seasons is reflected in increasingly shorter days during the summer
until the hours of daylight and nighttime are equal at the Autumnal Equinox or
the beginning of autumn in late September. At the same time, temperatures are
cooling after peaking in midsummer. One of the best parts of fall is the
beautiful display of leaves on deciduous trees as they change color. This change
occurs because they stop producing chlorophyll, the green pigment that converts
energy from sunlight into oxygen and carbohydrates that enable plant growth, and
other colors normally hidden by the green appear. How are the colors this
fall? Watch the animation above from a WeatherBug camera in Canaan, VT and see
how the colors change from green to yellow, orange and red from August to early
October. Relate these changes to this graph
of temperature and average hours of daylight for the same time period. WeatherBug
Meteorologist Rachel Peterson shows us when and where peak fall color occurs at
different locations across the U.S. in her Real World Instruction Video, Fall
Across the U.S. |
