The Truth About Groundhogs
When do groundhogs really come out of hibernation? Ask a local nature
center and send reports from your area to Mrs. Anderson's class in West
St. Paul, Minnesota. Address: 0197gel@informns.k12.mn.us
Mystery Class
A project to let students observe the dramatic changes in day length that
occur around the globe during spring in the northern hemisphere, and to
point out the central role this change plays in all natural systems. Record
the sunrise and sunset times where you live every MONDAY. On Friday
a report will arrive from our 11 Mystery Classes.
Robins
The Winter Robin Round Up survey is underway. If robins are
WINTERING in your area send reports to 7th graders at Valders
School in Wisconsin. Address: ddill@earth.execpc.com
Migrating Robins
As robins FIRST appear where you live this spring, send reports to:
jn_robin@informns.k12.mn.us
The Spring Fever Project
Prepare to test if it's true that robins move northward as the temperatures
average 36 degrees F. Get your thermometers ready!
Leaf-out dates
A Texas teacher just reported that the leaves are beginning to emerge
there! Our leaf-out mailbox opens for reports on Feb. 10th.
Ask the Expert
Deadline for sending questions to leatherback sea turtle biologist Dr. Ed
Standora is Wednesday, February 15th. Send your questions to:
jnorth@informns.k12.mn.us (Note change of address! The opening of several
of our mailboxes at the informns has been delayed. I apologize for the
inconvenience.)
Challenge Questions
There's still time to respond to these questions. Send your response to:
jnorth@informns.k12.mn.us
1) Who is Rachel Carson and what did she notice about robins?
2) Using the population figures Dr. Standora supplied (" There has been a
decrease in the number of nesting females from 115,000 in 1980 to between
20 and 30 thousand in 1992."), in how many years could leatherback turtles
become extinct if they continue to decline at their present rate? (You
might want to plot the figures on a graph to help you figure this out.)
