Calculate and Predict

  • Begin by calculating columns 4 and 5 (remember Teale's theory that spring advances 100 feet each day).
  • Next, watch for South Park Elementary in Pueblo to report their tulips emerging and enter the date into columns 6 and 7.
  • Use your calculations from column 5 to enter your predicted dates for the other towns in column 6.
  • Watch the Journey North Web site for the remainder of the schools to report tulips emerging, and record the dates into column 7.
  • After you have completed the table, check to see how accurately spring can be predicted using Teale's theory.
