News: Temperature Swings Warm and Cold

"We had a very warm week in early February. Our tulips have started to emerge due to this warm period. Now it is cold again, we hope it doesn't hurt our tulips. "

Are springtime temperatures ever steady? How do the swings in temperature affect the tulips? As temperatures rise and fall across the continent what kind of patterns do you see?

Do the Math:
We now have 73 gardens emerging out of 463 planted. What percent have emerged?

Discoveries in the School Yard
Hepburn-Lycoming Elementary School, Cogan Station, PA, 02/24/09
"While outside for recess today it was discovered that several of our tulips had emerged. 60+ kindergarten children went crazy!
"They were so excited. We grabbed cameras and took pictures, we wrote to our pen pals at another elementary school, we wrote another page in our class journal, and we wrote a sentence strip and made an illustration for our 'hallway tulip news.' The students were so excited that this was the topic of conversation for the rest of the afternoon."
Explore: Does Spring Journey North?
Mapping the Green Wave of Spring
Journey North uses tulips to indicate spring's arrival throughout the country.

 

But here's a question to ponder: "Does spring truly move northward?"
Map the Data, Map the Wave
Just as the lines on this weather map show places that have the same temperature you can use your own Journey North map to draw the advancement of spring! Will it move northward?

Garden Sleuths: Spring Along the 45 Degree Line
This week we're exploring the question about spring's movement across the continent. Five tulip gardeners have volunteered to help us. Each of their gardens is found along 45 degrees North, from the East coast to the western edge of the continent. Each is almost exactly the same distance from the Equator.

Read descriptions of each of the 5 garden locations. You be the detective and decide if you think they will emerge at the same time, or predict otherwise!
