Data and Maps: Wacky Spring Weather Reported

"We decided to let everyone know that we have had WACKY WEATHER! We think our Tulips are confused due to the frequent changes in temperature. It will be freezing for a few days in the 30's and then jump up to the 70's."

Are springtime temperatures ever steady? How do the swings in temperature affect the tulips? We now have 93 gardens emerging out of 428 planted. What percent have emerged? As temperatures rise and fall across the continent what kind of patterns do you see?
This week tulips made an appearance in Washington D.C.. Students reported, "They're reddish-greenish. They're poking up from the ground. They're sort of circly and pointy."

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?

Explore: Robots Monitoring Temperatures IN the Garden 
With their first tulip emerging this week, students in Lebanon, OR are excited to share some of their work monitoring the microclimate in their school garden. Mr. Gullickson’s 6th grade Science classes report:

"Our class continues to monitor, chart, and graph the weekday temperatures in our garden. Awesome job Aide and Jazzy!
"As soon as our weather warms up we hope to have our LEGO robot helping us monitor our garden temps.
"We are also having fun tracking weekly tulip progress for more than 75 other schools located throughout North America."
Find out how this class is using
LEGO NXT robotics system to help monitor in the garden >>


Discover: How Freezing Temperatures Affect Plants

Did you know that most plants are more than 85% water?
What happens to plants when freezing temperatures hit? Makes you wonder, doesn't it!
Why not set up some cool experiments to explore this question?
Here's what you need: water, sugar, and a freezer. You could experiment on real, live plant leaves, too!
