The Green Wave of Spring
After mapping today's data, how far would you say the wave of spring has advanced? Imagine drawing this wave at different stages over the next months as spring moves across the continent. Such a line is called an "isopleth". ("Isopleth: A line on a map connecting points at which a given variable has a specified, constant value".)
Using this spring's tulip data, draw the wave (an isopleth) at regular time intervals to show spring's advance. The "given variable" could be "tulipsemerged" and your "constant value" could be a certain date. For example, you might choose each Monday's date as the date you'll draw your line. All gardens in which tulips have emerged as of that Monday would be included. You would draw your line by connecting the dots where tulips have emerged. Each week you would draw another line until the wave of spring has advanced across the entire region.
Finally, at the end of the season, you could measure the distances between the waves and determine out how you would complete this sentence:
"Spring advances at the average rate of xx miles per day."
Spring's Journey NORTH?
As you look where tulips have begun to grow, you may be surprised. How would you answer this question?
Tulips, Temperatures, and the Arrival of Spring
As described in the Spring Fever lesson, you can actually measure the
amount of heat it takes for your tulips grow and bloom. This heat is
measured in units called "Growing Degree Days". Now think about this:
Tulips are Tasty!
A word to the wise, from the students at Citrus Elementary in Vero Beach, FL:
