Class #1 has still not sent that date in. #2 5:35 am 5:51 pm #8 7:40 am 17:36 pm Mrs. Berger's Class K12ROBZJ@vaxd.hofstra.edu Joan Berger Internet Educational Consultant East Hills School Roslyn, New York 11577 Last week the students in Mrs. Biewald's class were worried that our friends at Mystery School #3 had too much sunlight to sleep. From the looks of today's sunrise and sunset data, their problems may finally be over. If you're worried that you'll NEVER figure out where these Mystery Classes are located, here's a suggestion: Graph the RATE photoperiod changes at each location and compare it against the rate of change at the only known location--your own. Here's how: 1) Divide your class into 12 groups. 2) Have each group chose one of the 11 Mystery Classes and have one group chose your own class. 3) Your goal is to make a graph that will show the number of minutes lost or gained at each location each week. Hold a classroom discussion and decide the scale that would work for your graph. 4) Each week as yourself these questions: At which sites is the photoperiod increasing? Decreasing? What does this tell me about each location? At which locations is photoperod changing the fastest? Where is it changing the least? What does the RATE of change tell me about the location of each class? Remember, on the first day of spring we'll begin to send some clues! WRITE ABOUT IT! Have you noticed that the days are getting longer where you live? Write a poem that captures the feelings that come with this sign of spring. Please include the many changes you observe in nature at this time of year where you live. Send your poem to: jnorth@informns.k12.mn.us On the first day of spring we'll share all the poems we've received with everyone.
